A 400% casino bonus is an exceptionally generous offer that multiplies your deposit five times — deposit £100 and play with £500. These premium promotions are rare in the UK market but can appear at select casinos looking to attract new players with maximum value.
How 400% Bonuses Work
The casino matches your deposit at four times the amount. A £50 deposit receives £200 in bonus funds, giving £250 total. Maximum bonus amounts vary but these offers typically cap at £200 to £500 in bonus funds.
Wagering requirements on 400% bonuses are typically very high, ranging from 50x to 80x the bonus amount. A £200 bonus at 60x wagering means £12,000 in total bets required before withdrawal.
Pros
- Five times your deposit value
- Maximum bankroll from minimal deposit

400% Bonus FAQ
Where can I get a 400% casino bonus in the UK?
