Matched bonuses for slots
10Bet's 100% bonus must be wagered on slots, and Casumo's 50% bonus counts slots at full weight – both suit slots players who want bonus cash rather than spins.

Anyone who plays slots most of the time.
How we check every offer
Michael checks each offer against the casino's own published terms before it appears on this page, and rechecks offers regularly. We show the significant terms – qualifying deposit or stake, spin value, wagering, expiry and any maximum win – next to every claim button, and we only list casinos licensed by the UK Gambling Commission. If an offer changes, we update the page and the "last checked" date.
Bonuses and responsible play
A bonus should add to your entertainment, never pressure you to gamble more. Decide your budget first and only then choose an offer that fits it. Set a deposit limit when you register, take breaks, and never deposit more to finish wagering or chase losses. If gambling stops being fun, our responsible gambling page lists free, confidential support.
Spin value matters
Free spins are almost always 10p each, so the number of spins is what drives value. A matched bonus gives flexibility over stake size – but remember the bonus max bet.
