What is a casino bonus and how does it work?

For example, a “100% up to £50” offer means if you deposit £50, you get an extra £50 to play with. You’ll then see £30 in bonuses and 30 spins on Fishin’ Frenzy hit your account. This offer is particularly strong in the 2026 market because it perfectly balances a cash match with a high volume of spins. The Free Spins and any winnings from them are subject to a 10x wagering requirement. NetBet is offering new customers 100 Free Spins on Big Bass Splash when they join, opt in through the Quests section and wager £20 or more on any slot game. MrQ currently offers up to 300 free spins with the POTS300 promo code.

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.
