Casino bonuses are the most discussed topic on this forum for good reason — they are also the most misunderstood. The headline figure a casino advertises (£200 welcome bonus, 200 free spins) tells you almost nothing about the actual value you will receive. What matters is the wagering requirement, the game contribution percentages, the maximum win cap, and the time limit.
Here is the honest maths. A £100 bonus with 30x wagering requires you to bet £3,000 before you can withdraw. Using a 4% average house edge on slots (96% RTP), your expected loss across that £3,000 of wagering is £120. So the expected value of the bonus is negative before you have even started. The bonus is still worth claiming if you enjoy playing and understand you are paying for entertainment, but you should not expect to profit from it as a rule.
Since January 2026, UKGC rules cap wagering at 10x maximum. A £100 bonus with 10x wagering requires £1,000 of bets, with expected loss of £40 at 4% house edge. That makes the bonus worth approximately £60 in expected entertainment value — a genuine improvement over the old 30x to 50x era. No wagering casinos like PlayOJO and All British Casino eliminate this calculation entirely, though their bonus amounts tend to be smaller.
Free spins bonuses have an additional trap: the maximum win cap. Most casinos cap free spin winnings at £2 to £5 per spin regardless of what you actually land. Check this figure before claiming.
