Casino Deposit Bonuses: How They Work
A deposit bonus rewards you for funding your account — typically by matching a percentage of what you deposit with bonus funds or free spins. Here's how the common types work.
Match bonuses
The most common form is a percentage match. A "100% match up to £50" means the casino adds bonus funds equal to your deposit, up to £50 — deposit £30 and you get £30 in bonus funds. A 50% match would add half your deposit.
The conditions
Deposit bonuses almost always carry wagering requirements, and bonus funds usually can't be withdrawn until those are met. There may also be a maximum bet while a bonus is active and an expiry date.
Bonus funds vs free spins
Some deposit offers give bonus cash, others give free spins, and some both. Which suits you depends on whether you prefer flexibility across games or spins on specific slots — see free spins vs bonus funds. For the conditions, see wagering requirements.
