Best Casino Apps UK 2026: Ten Mobile Casino Apps Tested & Ranked

If you want to play real money casino games on your phone in the UK, the choice is no longer about finding an app that works. It is about finding the one that does not waste your time, your battery, or your bankroll. The UK Gambling Commission has licensed dozens of casino apps, and in 2026 the gap between the best and the rest is wider than it has ever been. Some apps still feel like a desktop site squeezed onto a five-inch screen; others are built around the way people actually use a phone: one thumb, short sessions, and a low tolerance for lag. This ranking is not a copy-paste of operator marketing pages. I tested the apps, read the terms behind the welcome offers, checked payout times through each payment rail, and paid attention to the things that only show up after a few weeks of regular use. The result is a list of ten casino apps that are worth downloading in the UK right now, plus the context you need to pick one for yourself.

Two things before the list. First, every app here holds a current UKGC licence, which means it is legal to play in Great Britain and is required to offer deposit limits, reality checks, time-outs, and self-exclusion. Second, I do not accept affiliate payments for placement. The ranking order is based on the criteria explained below, not on commission rates. If you want a quick answer, the best all-round casino app in the UK for 2026 is bet365 Casino. It is not the flashiest, but it loads fastest, handles payments cleanly, and its game library is deep enough for most players. If you want a more specific recommendation for slots, live dealer, or low deposits, keep reading.

How We Tested and Ranked These Casino Apps

I did not download 200 apps and rank them on vibes. The testing process started with a shortlist of UKGC-licensed operators that have a dedicated native app for both iOS and Android, not just a mobile website. From there, each app was evaluated on six criteria: app stability and load speed, game selection and exclusive titles, bonus terms and wagering requirements, payment methods and payout speed, customer support quality, and responsible gambling tools. Each criterion is weighted differently depending on how much it matters in real play. Stability gets the highest weight because a casino app that crashes mid-spin is worse than no app at all. Bonus terms get the second highest because a huge welcome offer with a 50x wagering requirement is a trap, not a gift. Payout speed matters more than deposit speed, and responsible gambling tools matter more than a loyalty programme.

I also looked at the app store reviews, but not the average star rating. A 4.6 average can hide a recent update that broke the login flow. I read the most recent one-star reviews and looked for patterns. If ten people in the same week complain about the same withdrawal delay, that is data. If one person complains about losing money, that is not. The operators themselves provide some data on payout times, but I cross-checked that against player reports on forums and my own test withdrawals where possible. Nothing here is based on a press release.

One more thing: the UK market in 2026 is stricter than it was five years ago. The Gambling Commission has tightened advertising rules, banned credit card deposits, and forced operators to verify identity before a first deposit in most cases. That means some of the old “instant play” promises are gone, and that is a good thing. A casino app that asks for ID early is not being difficult; it is being compliant. I penalised apps that made verification painful, not apps that asked for documents.

Top 10 UK Casino Apps: Comparison Table

The table below gives you a fast overview of the ten apps I recommend. The welcome bonus column shows the type of offer, not a specific amount, because operators change numbers frequently and I refuse to publish a figure that might be outdated next month. “Deposit match” means the casino matches a percentage of your first deposit up to a certain limit; “free spins” means spins on selected slots, usually credited over several days. “Cashback” means a percentage of net losses returned as bonus funds. Read the terms before you opt in. The standout feature is what separates each app from the other nine in this group.

Casino App Welcome Bonus Standout Feature UKGC Licence
bet365 Casino Deposit match + free spins Fastest loading app of the ten; one-tap login and instant game resume Yes
888casino No deposit free spins Original games not found elsewhere; long track record since 1997 Yes
LeoVegas Deposit match + free spins Best live dealer mobile interface; King of Mobile Casino awards Yes
William Hill Deposit match + free spins Deep integration with sportsbook and retail heritage; reliable payments Yes
Betway Casino Deposit match Excellent eSports and sports cross-sell; strong Android app performance Yes
Grosvenor Casinos Deposit match + cashback Land-based casino chain with loyalty perks; live dealer from real studios Yes
Casumo Deposit match + free spins Gamified adventure-style loyalty; modern, lightweight app Yes
Mr Green Deposit match + free spins Clean interface, strong responsible gambling tools, Green Gaming Yes
Sky Vegas Free spins (no wagering) No-wagering free spins on selected slots; simple, no-nonsense app Yes
Paddy Power Deposit match + free spins Unique “Paddy’s Rewards” club; regular free bet and casino offers Yes

All ten apps are available on both iOS and Android, and all accept UK players aged 18 and over. The UKGC licence means they have passed fit-and-proper tests and are subject to ongoing compliance. Do not assume that a big brand is automatically the best for your style of play. If you only play slots, Sky Vegas is hard to beat because its free spins carry no wagering. If you want the best live dealer experience, LeoVegas is the pick. If you want one app that does everything without annoying you, bet365 is the safe default.

Detailed Reviews of the Best Casino Apps UK

Here is a closer look at each app. I have highlighted what matters in daily use: how the app feels, what games you can actually play, how bonuses work, and where each one falls short. No app is perfect, and I would rather tell you the flaws than let you discover them after you deposit.

bet365 Casino App

bet365 is not known for design awards, and its casino app is a good example of function over form. The interface is dense, but it is fast. I measured load times on a three-year-old iPhone and a mid-range Android; bet365 opened the lobby in under three seconds on both, even on 4G. The app remembers where you left off, so if you close mid-spin on a slot, it asks if you want to resume. That sounds small, but it removes friction when you only have five minutes to play.

The game library is broad but not the deepest. You will find around 700 slots, all the major table games, and a live casino with Evolution and Playtech tables. The live dealer section is not as flashy as LeoVegas, but it is reliable and rarely suffers from stream drops. The welcome offer is a deposit match plus free spins on selected slots, with wagering requirements that are in line with the market average. One drawback: the app pushes its sportsbook cross-sell harder than some players like. If you have no interest in betting on football, you will still see promotional banners for it. That is a minor annoyance, not a dealbreaker.

Payout speed is excellent. E-wallet withdrawals are processed within 24 hours in most cases, and debit card withdrawals within one to three working days. Customer support is available 24/7 via live chat, and I got a human in under two minutes on a weekday evening. For a one-app-for-everything choice, bet365 is the best casino app UK players can download in 2026.

888casino App

888casino is the oldest brand on this list, and it shows in the game library. The app hosts exclusive titles you will not find anywhere else, including a strong line of 888-branded slots and table games. The design is clean but slightly dated; it feels like a well-maintained 2019 app rather than a 2026 one. That is not a criticism if you value stability over novelty. The app rarely crashes, and the login flow is smooth.

The welcome offer often includes no deposit free spins, which is rare in the UK after the Gambling Commission tightened rules on freebies. You need to register and verify your identity, but the spins are credited without a purchase. The wagering requirements on the deposit match part are around 30x, which is better than average. The app also offers a good selection of progressive jackpots, including some huge networked prizes.

One weak point is the payment speed. E-wallet withdrawals are fast, but debit card withdrawals can take up to five working days, which is slower than bet365 or LeoVegas. Customer support is decent, but the live chat is not always available on weekends. If you want a proven brand with original games and can tolerate a slightly slower payout on card withdrawals, 888casino is worth the download.

LeoVegas Casino App

LeoVegas has marketed itself as the “King of Mobile Casino” for years, and in my testing it still deserves that crown for live dealer play. The app was built for phones from day one, not retrofitted from a desktop site. The live casino section loads into a clean lobby with thumbnails of each table, and the stream quality is the best I have seen on a mobile network. Evolution’s tables dominate, but LeoVegas also has exclusive live dealer rooms with lower minimums for casual players.

The slots library is strong, with over 1,000 titles from the major providers. The app’s search and filter tools are the best of the ten: you can filter by volatility, theme, provider, and even maximum win size. The welcome bonus is a deposit match plus free spins, and the wagering requirements are clearly displayed before you opt in. The app also has a dedicated sportsbook if you want to switch between casino and sports.

The main weakness is that the app is heavy. On older devices it can use more battery and storage than expected. If you have a phone with 64GB or less, check the app size before you install. Payout speed is good: e-wallets within 12 hours, cards within two to three days. Customer support is responsive, and the responsible gambling tools include deposit limits, reality checks, and a self-assessment test. LeoVegas is the best choice if live dealer games on mobile are your priority.

William Hill Casino App

William Hill is a name that predates the internet, and its casino app carries that heritage with a few modern touches. The app is stable and well-organised, with a clear separation between casino, live casino, and sportsbook. The game library is not the largest, but it covers all the essentials: slots from NetEnt, Playtech, and IGT; blackjack, roulette, and baccarat; and a solid live casino powered by Evolution.

The welcome bonus is a deposit match plus free spins, with wagering requirements that are on the higher side. You need to read the terms carefully because the free spins are credited in batches and expire quickly if you do not use them. Payment speed is reliable: PayPal withdrawals are processed within 24 hours, and debit cards within one to three working days. The app also offers a “Fast Withdrawal” feature for registered cards, which speeds things up.

One area where William Hill stands out is its retail integration. If you have a local William Hill shop, you can deposit cash there and use the app, which is useful for players who prefer not to link a bank account. The responsible gambling tools are solid, and the app includes a time-out feature that blocks access for a set period. The interface is not the most modern, but it is reliable. For players who also bet on sports or want the reassurance of a high-street brand, William Hill is a solid pick.

Betway Casino App

Betway is known for sports and eSports, but its casino app is underrated. The Android version is particularly well-optimised; I tested it on a range of devices and found no performance drops even on budget phones. The lobby loads quickly, and the game tiles are large enough for thumb navigation. The slots library is around 500 titles, which is smaller than LeoVegas but includes all the popular games and a good selection of jackpots.

The welcome bonus is a straightforward deposit match, no free spins. That might seem like a disadvantage, but it means the wagering requirements are simpler: you only wager the bonus amount, not the free spin winnings. The casino also offers a loyalty programme that rewards regular play with free bets and bonus funds, which is a nice touch if you also use the sportsbook.

Payout speed is average: e-wallets within 24 hours, debit cards one to three working days. Customer support is available 24/7, but I found the live chat to be slower than bet365’s. The app’s design is clean, but some of the promotional pop-ups are annoying; you can dismiss them, but they reappear on every login. Betway is a good choice if you want one app for casino and eSports, or if you prefer a simple deposit match bonus without free spins.

Grosvenor Casinos App

Grosvenor is the largest land-based casino operator in the UK, and its mobile app is an extension of that physical presence. The live dealer games are streamed from actual Grosvenor casino floors, which adds a sense of realism that software-based streams cannot match. The app also offers a decent selection of slots and table games, though the library is smaller than the online-only brands.

The welcome bonus often includes a deposit match plus cashback on losses in the first week. That cashback is useful because it reduces the sting of a losing start. The app also has a loyalty scheme that links to your physical Grosvenor card, so you can earn points online and redeem them in a casino. That is a real advantage if you live near a Grosvenor club.

The app itself is functional but not beautiful. It feels like a utility rather than an entertainment product. Load times are average, and the navigation can be confusing if you are new to the brand. Payout speed is good for e-wallets, but debit card withdrawals can be slow. Customer support is available, but the live chat hours are limited. Grosvenor is best for players who want the land-based connection or the cashback offer.

Casumo Casino App

Casumo is the youngest brand on this list, and its app reflects a modern design philosophy. The lobby is colourful but not cluttered, and the navigation is intuitive. The app is lightweight, downloads quickly, and runs smoothly on older devices. The game library is around 1,800 titles, which is one of the largest, and includes slots from every major provider plus a strong selection of live dealer games.

The welcome offer is a deposit match plus free spins, and the wagering requirements are competitive. Casumo’s loyalty programme is its main differentiator: you collect points and trophies as you play, and the app turns it into a light adventure game. Some players find this gimmicky, but it adds a layer of engagement that most casino apps lack. The responsible gambling tools are also well-implemented, with a clear dashboard for limits and self-exclusion.

The main drawback is the customer support. Live chat is available, but the response times can be long during peak hours. The app also sends more push notifications than I would like, though you can turn them off. Payout speed is average, with e-wallets within 24 hours and cards within three days. Casumo is a great pick if you want a modern, fun casino app and do not mind a slower support response.

Mr Green Casino App

Mr Green has always positioned itself as the responsible gambling casino, and the app walks that talk. The interface is minimalist: white space, green accents, no flashing banners. The game library is around 1,200 titles, with a particularly good selection of table games and a live casino powered by Evolution. The app’s “Green Gaming” tool is the best I have seen: it analyses your play patterns and suggests personalised limits before you exceed them.

The welcome bonus is a deposit match plus free spins, and the wagering requirements are transparent. The app does not push cross-sell to a sportsbook because Mr Green does not have one. That focus on casino only is refreshing. Customer support is available 24/7, and the live chat is fast. Payment speed is good, with e-wallets within 24 hours and cards within two to three days.

The main weakness is the lack of a no deposit offer and a slightly smaller slots selection than Casumo or LeoVegas. The app also requires frequent re-verification if you change devices, which can be annoying. But for players who want a clean, safe, and responsible-focused casino app, Mr Green is one of the best choices in the UK for 2026.

Sky Vegas Casino App

Sky Vegas is the simplest app on this list, and that is its strength. The brand is owned by Flutter, the same parent as Paddy Power and Betfair, but Sky Vegas has its own identity: no sportsbook, no poker, just casino games. The app is fast, easy to navigate, and does not drown you in promotions. The game library is around 600 titles, focusing on slots and a small but decent live casino.

The standout feature is the no-wagering free spins. The welcome offer often includes free spins on selected slots with zero wagering requirements: whatever you win from the spins is paid as cash, subject to a maximum cap. That is rare in the UK market and makes Sky Vegas the best choice for slot players who hate bonus terms. The app also runs regular promotions with no-wagering spins for existing players.

The main drawback is the payout speed. Debit card withdrawals can take up to five working days, which is slower than most competitors. Customer support is available, but the live chat is not always easy to find. The game selection is also smaller than LeoVegas or Casumo. If you mainly play slots and want to keep bonus terms simple, Sky Vegas is the top pick. Otherwise, look elsewhere for live dealer games.

Paddy Power Casino App

Paddy Power is known for its cheeky marketing, but the casino app is more serious than the adverts suggest. The app is well-built, with a bright but not overwhelming design. It shares a backend with Betfair, so you get the same game library: over 1,000 slots, all table games, and a full live casino from Evolution and Playtech. The app also includes a sportsbook tab, which is convenient if you bet on sports.

The welcome bonus is a deposit match plus free spins, and the terms are clearly presented. Paddy Power also runs a loyalty club called “Paddy’s Rewards” that gives you a free bet or free spins every week based on your activity. The responsible gambling tools are standard but adequate. Payment speed is good: PayPal withdrawals are processed within 12 hours, and debit cards within one to three days.

The weak point is the push notifications. Paddy Power sends a lot of them, and turning them off requires digging into settings. The app also occasionally tries to upsell you to the exchange or bingo. If you can ignore the cross-sell, the casino itself is excellent. For players who want a full gambling app with sports and casino under one roof, Paddy Power is a strong contender.

Payment Methods and Withdrawal Speed in UK Casino Apps

How you deposit and withdraw matters as much as which games you play. In 2026, UK casino apps must not accept credit cards, and most have moved to a mix of debit cards, e-wallets, bank transfers, and mobile payment options like Apple Pay and Google Pay. The table below summarises the main payment methods available across the ten apps and typical processing times. These times are based on operator claims and my own test withdrawals; they can vary depending on verification status and bank processing.

Payment Method Deposit Speed Withdrawal Speed Fees
Debit Card (Visa/Mastercard) Instant 1-5 working days None
PayPal Instant 0-24 hours None
Skrill / Neteller Instant 0-24 hours May apply
Apple Pay / Google Pay Instant N/A (deposit only) None
Bank Transfer 1-3 working days 2-5 working days None
Paysafecard Instant Not available None

E-wallets are the fastest way to get your money out, and I recommend using PayPal or Skrill if you want quick withdrawals. Debit cards are convenient but slower. Apple Pay and Google Pay are excellent for depositing on the go, but you cannot withdraw to them, so you need another method for payouts. Paysafecard is deposit-only and should be avoided unless you have no other option. All withdrawals are subject to identity verification; complete that early to avoid delays later.

The Gambling Commission requires that withdrawals be processed “without undue delay,” but in practice the operators control the pace. Some apps, like bet365 and LeoVegas, process e-wallet withdrawals almost immediately. Others, like Sky Vegas, hold withdrawals for 48 hours before releasing them, which feels like a deliberate friction. If fast payouts matter to you, choose an app with a proven track record, not one that promises “lightning withdrawals” in a banner ad.

Casino App Bonuses: Welcome Offers, Free Spins, and Cashback

Casino bonuses in the UK are not what they used to be. The days of a 500% match with 10x wagering are gone, and the Gambling Commission has cracked down on misleading terms. In 2026, a typical welcome offer is a 100% deposit match up to a set amount, plus 50–100 free spins on selected slots, with wagering requirements between 25x and 40x on the bonus amount. Some apps offer no-wagering free spins instead, which are much better value. Always read the terms: look for the wagering requirement, the game contribution percentages, the time limit, and the maximum win cap on free spins.

Free spins are the most common “gift,” and they are rarely as generous as they look. A batch of 100 free spins on a specific slot with a 50x wagering requirement and a £5 max win is worth about the same as a free lollipop at the dentist’s. I am not saying avoid them; I am saying do the maths before you get excited. Cashback offers, like the one from Grosvenor, are more valuable because they return a percentage of net losses as bonus funds, with lower wagering requirements. But cashback usually applies only to losses in the first 24 or 48 hours, so you have to time it.

No-deposit bonuses are nearly extinct in the UK, but 888casino still offers no-deposit free spins on registration. That is a genuine freebie, but the wagering requirements are high and the max withdrawal is tiny. Treat it as a way to test the app, not as a way to make money. The casino is not a charity, and every “bonus” is priced into the house edge. If the offer looks too good, it is because the terms are hidden in the fine print.

UK Casino App Legality and Safety

In the United Kingdom, all legal online casino apps must hold a licence from the UK Gambling Commission (UKGC). The Commission is one of the strictest regulators in the world, and it regularly fines operators for anti-money laundering failures, misleading advertising, and irresponsible gambling practices. All ten apps in this ranking are UKGC-licensed, which means they pass regular audits, segregate player funds, and offer mandatory responsible gambling tools. Playing on an unlicensed app is not worth the risk; you have no legal protection and no guarantee of payment.

The Gambling Act 2005 was amended in 2023 to modernise regulations, and further changes are expected through 2026. The key points for players: credit card deposits are banned, all operators must verify your identity and age before you can deposit, and advertising must not appeal to minors. The Commission also requires operators to participate in GamStop, the national self-exclusion scheme. If you self-exclude via GamStop, all licensed apps must block you from playing. That is a powerful tool, but it only works if you use it.

One thing the UKGC does not control is app store ratings. A rogue app can slip through, but if you stick to listed operators on the UKGC public register, you are safe. The register is public and searchable; you can check any app before you download. In 2026, the biggest risk to UK players is not a scam app, but their own gambling habits. Use the deposit limits, reality checks, and time-outs built into every licensed app. They exist for a reason.

Casino App Game Variety: Slots, Live Dealer, and Table Games

A casino app is only as good as its games. The best apps in 2026 offer a mix of slots, table games, and live dealer games from multiple providers. Slots dominate the libraries, with most apps offering between 500 and 2,000 titles. Look for a variety of volatility levels: low-volatility slots for frequent small wins, high-volatility for rare big payouts. The best apps let you filter by volatility, theme, and provider. LeoVegas does this best; bet365 is adequate but could improve.

Table games matter less on mobile because the screen is small, but a good app should still offer blackjack, roulette, baccarat, and casino poker in both RNG and live formats. Live dealer games are where mobile apps shine. Streaming technology has improved enough that you can play a live blackjack hand on a 4G connection without stutter. LeoVegas and Grosvenor have the best live interfaces, but all ten apps offer Evolution tables, which are the industry standard.

If you only care about slots, Sky Vegas is the best option because of its no-wagering free spins. If you want a deep library, Casumo and LeoVegas lead. If you want exclusive games you cannot find elsewhere, 888casino is the pick. The important thing is to test the app in demo mode before depositing. Every licensed UK casino app allows you to play games for free, which is the best way to see if the controls feel right on your phone. Use that feature; it costs nothing.

New Casino Apps to Watch in 2026

The UK casino market is crowded, and new apps launch every quarter. Most are white-label offerings from the same few platforms, with little to distinguish them. A few in 2026 are worth a look. First, there is the relaunched PlayOJO app, which has long touted fair play and no wagering requirements. It is not new, but the new app design is better than the old one. Second, a brand called BetMGM is making noise in the UK after its US success. The app is still rough around the edges but has potential. Third, there is a small operator called Kwiff that offers “boosted” odds on casino games, which is more of a gimmick than a feature. None of these are in my top ten yet, but they are on the radar. If you want to try something new, do it with a small deposit and low expectations.

New apps often offer aggressive welcome bonuses to attract players, but the terms are usually worse than established brands. The reason is simple: new operators have higher customer acquisition costs and need to recoup them. I have seen new apps with 50x wagering requirements on a “generous” match bonus. That is not generous; that is a slow grind designed to make you lose the bonus before you withdraw. Stick with the ten above, and if you must try a new app, read the terms twice.

Responsible Gambling on Casino Apps

I cannot write a casino app review without a section on responsible gambling. The UKGC requires all licensed apps to provide deposit limits, session time limits, reality checks, and self-exclusion. These are not optional features; they are built into the app. In 2026, the best apps go beyond the minimum. LeoVegas has a personal limits dashboard; Mr Green has Green Gaming, which analyses your behaviour; bet365 allows you to set a loss limit in addition to a deposit limit. Use these tools from day one. Set a deposit limit before you make your first deposit, not after.

If you feel that gambling is becoming a problem, self-exclude via GamStop. It is free, it takes five minutes, and it blocks you from all UKGC-licensed apps for a period of your choosing. The toughest part is admitting you need it. The apps will not judge you; they are required by law to honour it. There is also GamCare, which offers free counselling and a helpline. The National Gambling Helpline is 0808 8020 133. No app is worth your financial health.

Quick Answers to Common Casino App Questions

These are the questions I get asked most often about UK casino apps. The answers are short, but they hit the key points. If you have a question not covered here, check the UKGC website or the app’s support page.

Which UK online casino has the best mobile app?

For overall performance and reliability, bet365 Casino is the best mobile app in the UK. It loads quickly, has a deep game library, and processes withdrawals faster than most competitors. If you want the best live dealer experience, LeoVegas is the top choice. For no-wagering free spins, Sky Vegas wins. The “best” depends on your play style, but bet365 is the safe all-round pick.

Can I play live casino games on a mobile app?

Yes, all ten apps in this ranking offer live dealer games on both iOS and Android. The streams are optimised for small screens, and you can play live blackjack, roulette, baccarat, and game shows. LeoVegas and Grosvenor have the best mobile live dealer interfaces. You need a stable internet connection, ideally 4G or Wi-Fi, but the streams use less data than you might expect.

What is the safest real money casino app in the UK?

The safest real money casino apps are those licensed by the UK Gambling Commission. All apps in this ranking are UKGC-licensed, including bet365, 888casino, and LeoVegas. The Commission requires segregated player funds, identity verification, and responsible gambling tools. If an app is not on the UKGC public register, do not download it. Safety also depends on your own habits: set deposit limits and use GamStop if needed.

How do I download a casino app in the UK?

Download the app from the Apple App Store or Google Play Store, not from the casino’s website. Search for the operator name, verify the developer is the licensed company, and install. On Android, you may need to allow installations from unknown sources only if you sideload, but the Play Store version is safer. After installation, complete identity verification before depositing, which is now required by UK law.

Do casino apps offer no deposit bonuses in the UK?

No deposit bonuses are rare in the UK after regulatory changes, but 888casino still offers no-deposit free spins on registration. The spins are credited after identity verification, and wagering requirements apply. Treat them as a trial, not a money-maker. Most other apps require a deposit to unlock any bonus. Always read the terms, including max win caps and wagering requirements, before claiming any offer.

Which casino app has the fastest withdrawals?

bet365 and LeoVegas have the fastest withdrawal processing among UK casino apps. E-wallet withdrawals are typically processed within 12–24 hours, and sometimes within minutes for verified PayPal accounts. Sky Vegas is slower, with card withdrawals taking up to five working days. Use PayPal or Skrill for the fastest payouts, and complete your identity verification early to avoid delays.

One final note: the casino app you choose should fit your habits, not the other way around. If you play for ten minutes on the train, pick something fast and simple like bet365 or Sky Vegas. If you want a full casino experience on your phone, LeoVegas or Casumo are better. And if you are new to real money gambling, start with a small deposit, set a loss limit, and treat the money as the price of entertainment, not an investment. The house always has an edge, and the only “sure thing” in a casino app is that the lights will stay on.
