Welcome Deposit Match
The standard 100% first-deposit bonus, decoded
A deposit-match welcome adds bonus credit equal to a percentage of your first deposit, up to a cap. A 100% match up to £200 means deposit £100 and play with £200; deposit £200 and play with £400; deposit £500 and you still only play with £400.
The real value is not the cap - it is the ratio of bonus to wagering. A £200 match with 10x wagering requires £2,000 of total stakes to clear, returning roughly £80 of expected value at a 96% RTP slot. The same £200 match at 60x wagering requires £12,000 of stakes and is structurally unbeatable for most players.
From January 2026 the UKGC capped UK casino wagering at 10x, which radically improved the value of welcome matches in Britain. US offers vary by state but most regulated jurisdictions stay in the 1x–25x band on the bonus portion.
Always check the maximum stake while a bonus is active (often £5 or $5 per spin), the contribution rate by game type (slots 100%, blackjack often 10% or 0%) and the expiry window (typically 7 to 30 days).

Frequently asked
Should I always deposit the maximum?
Only if you would have deposited that amount anyway. Bonus money is locked behind wagering, so don't deposit beyond your normal bankroll just to maximise a match.
