But we want to make things even more fun for you, and to do that, we like to run casino promotions. If it’s a bonus percentage of 200% up to £300, then a deposit of £50 can potentially get you a bonus of £100. This is a number (usually in the range of 50% – 200%) that refers to how much of your deposit you can match as a bonus.

Generally speaking online slots will contribute the most (often 100%), whilst table games contribute less (10–20%) For example, someone may believe they can withdraw bonus funds immediately, only to discover wagering still needs to be completed. Non-sticky bonuses can be separated from your deposit and are used after you’ve used your deposited funds. Most offers will come with wagering requirements that you’ll need to meet first.

This is why checking contribution rates is essential before choosing which games to play. A £10 bet only reduces the player’s wagering by £1. Let’s say a player has £1,000 left to wager and they play slots with 100% contribution To keep bonuses fair and sustainable, casinos weight contributions differently. Different casino games have different house edges and volatility levels.
