Casino bonuses by game: why the game decides the value

Casino bonuses by game is the part of the site that answers a simple question: can I use this bonus on the game I actually want to play, and is it worth it there? The answer changes from game to game. A bonus that works well on slots can be almost useless on blackjack, because the terms may exclude table games, count them at a fraction of their stake towards wagering, or not allow them at all while bonus funds are active.

Three things decide how a bonus behaves on a game. First, whether the game is eligible at all; free spins are always tied to named slots. Second, how much each bet counts towards any wagering, known as the contribution percentage. Third, the game's house edge, because the cost of clearing wagering is roughly the wagering total × the house edge. A £25 bonus at 10x needs £250 of bets; on a slot with a 4% house edge that costs about £10 on average.

None of this makes a game easier to win. Bonuses never change a game's odds, and every game keeps its house edge whatever balance you play with. The cards below lead to a page for each game type, from slots and Megaways to roulette, live casino and bingo.

How casino bonuses by game compare

Contribution rates are set by each casino's terms, so the middle column describes what bonus terms commonly say rather than a fixed rule. Always check the promotion page for the exact list.

Among our partners, 10bet's welcome bonus must be wagered on slots, Casumo's terms say game restrictions apply, and the three spins offers run on slots only. For the reasoning behind exclusions, read why some games are excluded from bonuses.

Bonuses by game

What 10p free spins are worth on popular slots

Because most UK bonuses end up on slots, the slot itself shapes what a spins offer is worth. The table uses published RTP, volatility and maximum win figures. Average return is spins × stake × RTP, a long-run figure; 100 spins is a short sample, and high-volatility games in particular can return nothing or far more.

Casinos can run different RTP versions of the same game, so check the help screen before you play; UK rules require the RTP or likelihood of winning to be available before play under the Commission's game information standard, RTS 3 (opens in a new tab). PlayOJO's 80 spins at 10p are on Big Bass Bonanza (18+, first deposit £10+, no wagering, terms apply); Coral and Ladbrokes list their own selected games on the promotion page.

UK rules on games that changed how bonuses work

Several game rules sit underneath every bonus term. The slot stake limits apply per game cycle and are explained in the Commission's online slots stake limit guidance (opens in a new tab). A bonus max-bet rule, such as Casumo's £5, can be lower than the legal limit but never higher.

• 31 October 2021: slot design rules banned autoplay, turbo and slam-stop, set a 2.5-second minimum spin and stopped losses being celebrated as wins; see slot game design rules.
• 17 January 2025: those rules extended to other online casino games, with a 5-second minimum per game cycle.
• 9 April 2025: £5 maximum stake per spin on online slots for players aged 25 and over.
• 21 May 2025: £2 maximum for players aged 18 to 24; read online slot stake limits.
• 19 January 2026: one incentive can no longer cover more than one product, such as casino and bingo together, as the Commission set out when it announced the promotion changes (opens in a new tab).

Feature buys aren't offered on slots at UK-licensed casinos, which is how games are supplied to Great Britain, so bonus funds can't be used to buy a bonus round.

The design rules sit in the Commission's RTS 14 standard on responsible product design (opens in a new tab), and they have a practical effect on bonus play. With a 2.5-second minimum and no autoplay, 100 free spins take at least four minutes and each one has to be started by hand. Bonus rounds that need no extra stake, such as a free spins feature triggered inside the slot, are exempt from the speed requirement.

How to use the game bonus pages

1. Open the card for the game you plan to play, not the one with the biggest offer.
2. Check whether the game is eligible and what share of each bet counts towards wagering.
3. Work out the wagering cost using that game's house edge, or use the wagering calculator.
4. Read game weighting explained if the terms give different rates for different games.
5. If your game is excluded, consider playing without a bonus rather than switching to a game you don't enjoy.

For table games there is a dedicated walk-through, how bonuses work on table games, and for live dealers the live casino wagering guide explains why most welcome offers leave them out.

Choosing a bonus for the games you play

If you play mainly slots, almost any offer will work, and the choice comes down to free spins against a deposit match. No-wagering spins from Coral (100 spins at 10p after a £10 slots bet), Ladbrokes (up to 500 spins at 10p over ten days after £10 of slots play) and PlayOJO suit low-stakes players; payment exclusions and expiry apply, 18+. If you prefer table games or live dealers, it is often better to skip the bonus, because exclusions and reduced contribution can make the wagering impossible to finish within the deadline.

Whichever game you choose, set a budget before you start and use the deposit limit the casino offers when you sign up. The slots vs table games comparison puts the two side by side, and our casino bonus reviews list each partner's eligible games.

Jackpot and Megaways slots need a second look. Some casinos exclude progressive jackpot games from bonus play, and a deposit match may cap what bonus winnings can be withdrawn; 10bet's cap is £1,000. On high-volatility games, most of a slot's return comes from rare large wins, so a small bonus balance often runs out before one arrives. That is normal variance, not a sign that anything is wrong, and it is a good reason to keep stakes small and stick to your budget.
