Matched deposit bonus

How a matched deposit bonus works

The casino looks at your qualifying deposit, multiplies it by the match percentage and credits that much as bonus funds, stopping at a stated cap. Your deposit stays as cash; the matched part sits alongside it as restricted money until the wagering requirement is met.

Three numbers define every offer: the percentage, the cap and the minimum deposit. Then come the conditions that shape how you can use it: the wagering multiple, the time limit, the max bet rule, any game weighting and sometimes a win cap on bonus winnings.

Matched deposit table: what each deposit gets you

The two partner offers below show how percentage and cap interact. The cap is reached at £25 for a 100% match up to £25, and at £200 for a 50% match up to £100.

10bet’s minimum deposit for the bonus is set in its terms; check the cashier before paying in. 10bet requires the wagering on slots within 3 days and caps bonus winnings at £1,000. Casumo requires opt-in, wagering within 7 days and a £5 maximum bet while the bonus is active, with game, play and payment restrictions. Both are for new customers aged 18+.

What a matched deposit is really worth

Bonus funds are not cash, because clearing them costs the house edge on every pound wagered. A quick estimate: bonus − (bonus × multiple × house edge). On a slot at 96% RTP, the edge is 4%.

• £25 bonus at 10x: £250 of wagering × 4% = £10 expected cost, leaving about £15.
• £100 bonus at 10x: £1,000 × 4% = £40 expected cost, leaving about £60.
• £10 bonus at 10x: £100 × 4% = £4, leaving about £6.

So at the 10x cap, a matched bonus keeps roughly 60% of its face value on average when played on a 96% slot. Individual results swing widely either side, and a high-volatility slot can wipe the balance before wagering is done. Losses on your deposit stay likely over time whatever the bonus does.

Choosing how much to deposit for a match

The tempting move is to deposit whatever reaches the cap. A better order is to decide your budget first, then see what match it earns.

1. Set the amount you would deposit if there were no bonus at all.
2. Check the minimum deposit and whether your payment method qualifies.
3. Work out the bonus that amount earns and the wagering it brings.
4. Divide the wagering by your usual stake to get the spins needed, then compare with the time limit.
5. Opt in, deposit and confirm the bonus balance appears before you play.

100%, 50% and other match percentages

A 100% match doubles a deposit up to the cap, so it gives the most bonus per pound at small amounts. A 50% match needs twice the deposit for the same bonus but often comes with a higher cap. Larger multiples such as 200% or 300% exist in some markets, usually with lower caps or tighter terms. Read our pages on the 100% slots bonus and the 50% slots bonus for how the two common versions compare.

Terms that travel with a matched deposit

Matched bonuses are often discussed with sticky bonus structures, bonus expiry windows and the opt-in step. If you prefer offers without wagering, compare with no wagering free spins.
