Best online casinos in the UK

Check local rules first

Rules on online gambling differ by country and can change. Before you sign up anywhere, including at the casinos on this page, check what applies where you live.

Names you will recognise

The UK has some of the most familiar gambling brands in the world, and most players already have an account with at least one of them. That is useful context, because the right "alternative" depends on what you use your current site for.

Notice the pattern: four of those seven started life as bookmakers. For a lot of UK players the casino is something you wander into after placing a bet on Saturday's football. That shapes our ranking below. If that is you, a casino with a sportsbook on the same account matters more than an extra percentage point on a slot bonus.

Offers at all of these brands change often, so check their current welcome offer on their own sites rather than relying on anything you remember from an advert.

Our picks for UK players

1. YourWin24, YOUR250. The obvious first pick for a UK audience: casino and sportsbook under one login, and a 250% first deposit bonus. If you bet on football and spin a few slots at half-time, this is the one. Read the YourWin24 review or see it against bet365, Paddy Power and William Hill.
2. CasinoWinner, WIN300. The biggest percentage match in the group at 300%. Best for slot players who want the most bonus balance from a modest first deposit, and who are happy to read the wagering terms properly. See CasinoWinner vs 888casino.
3. ZeSlots, ZESLOTS250. If Sky Vegas is your usual haunt, ZeSlots is the closest in spirit: slots first, everything else second, and a 250% match. The ZeSlots vs Sky Vegas page goes into detail.
4. CasinoPurple, PURPLE100. A straightforward 100% match, a tidy lobby and live dealer tables. A good fit if you find bigger matches more trouble than they are worth.
5. LuckySlotPlay, LUCK5. €5 free, no deposit needed. The low-commitment way to try a new casino before deciding anything.
6. Cas2Bet, CAS100. A plain 100% match on a no-nonsense site; compare it with Betway in Cas2Bet vs Betway.

Football, and why it changes the ranking

British players bet on football more than anything else, and the weekend rhythm of Premier League fixtures drives a lot of casino play too. A separate sports account and casino account means two balances, two sets of limits and two apps. With YourWin24 it is one wallet, and the welcome bonus code YOUR250 goes in when you make your first deposit. Our sports betting guide explains in-play betting and how to keep your stakes under control.

If you do not bet on sport at all, ignore this section. CasinoWinner or ZeSlots will give you more for a slots-only session.

What to check before you deposit

• The app. All six have an iPhone and Android app that you install directly from the casino website, without going through a store. It takes under a minute; the casino apps guide walks you through it.
• The cashier. Check the cashier for the deposit and withdrawal methods shown in your country before you sign up, not after.
• Verification. Expect to confirm your identity before your first withdrawal. Have it done early so a win is not held up.
• The bonus terms. Every match bonus carries a wagering requirement. Our wagering requirements guide shows how to work out what you actually need to play through.

Comparing offers like for like

Adverts make every welcome offer sound enormous, and comparing them honestly takes a minute of arithmetic. Here is how we would do it with the six casinos above:

1. Decide your first deposit before you look at any offer. The right bonus for a £20 player is not the same as for a £200 player.
2. Work out the bonus. With a 100% match (CasinoPurple PURPLE100, Cas2Bet CAS100) your deposit is doubled. With 250% (ZeSlots ZESLOTS250, YourWin24 YOUR250) you get two and a half times your deposit as bonus. With 300% (CasinoWinner WIN300) you get three times.
3. Check the wagering. Read the multiple in the bonus terms and multiply. That is the amount you need to stake before bonus money becomes withdrawable.
4. Be honest about your habits. If you play twice a month, a smaller bonus you can actually clear beats a big one that expires.
5. Consider starting free. LuckySlotPlay's LUCK5 gives €5 free with no deposit, which is a decent way to try a casino before any of the above matters.

The same logic applies when you compare against the big names in the table at the top. Check their current offer on their own site, run the same five steps, and the answer usually becomes obvious.

Slots after the match

Many UK players finish a football afternoon with a few spins. If that is your routine, a few habits keep it fun: set the slot budget separately from your betting budget, avoid buying bonus features when you are chasing a result, and stop when the session budget is gone, win or lose. Our online slots guide explains volatility and features in plain English, and you can try games for free at Free Casino Lobby first.

Safer play in the UK

Set a deposit limit on day one, before you have a reason to change it. Take breaks, and never chase a losing run.
