A 400% first deposit bonus multiplies your initial deposit by five — deposit £100 and play with £500. This is one of the highest match percentages available in the UK casino market and provides exceptional value for players making their first deposit.
How 400% First Deposit Bonuses Work
The casino matches your first deposit at four times the amount. A £50 deposit earns £200 in bonus funds, totalling £250. Maximum bonus amounts typically cap at £200 to £500.
Wagering requirements are typically 50x to 80x, the highest in the market. A £200 bonus at 65x requires £13,000 in total wagers. Game contributions are usually weighted, with slots counting 100% and table games 10-20%.

400% Bonus FAQ
Is a 400% bonus too good to be true?
Not necessarily, but the very high wagering requirements (50x-80x) make it difficult to convert to withdrawable cash. Always read the full terms.
Which UK casinos offer 400% bonuses?
These are rare and typically found at newer or smaller casinos. Always verify the operator holds a valid UKGC licence.
