Sign up at Booming Slots, deposit £10 or more, and the casino matches your first deposit by 100% up to £25. You get 50 free spins on Big Bass Bonanza, each worth £0.10. The Booming Slots welcome bonus is open to new accounts making a first deposit.
What the Booming Slots welcome offer gives you
The Booming Slots welcome offer has two parts: a 100% deposit match capped at £25, and 50 free spins on Big Bass Bonanza.
Deposit £10 and Booming Slots adds £10 in bonus funds. Deposit £25 and you receive the full £25. Booming Slots adds no match on deposits above £25, so a £25 deposit unlocks the full value of the Booming Slots casino welcome bonus.
Your 50 free spins carry a £0.10 spin value, so Booming Slots hands you £5 of spins. Winnings from those spins have their own wagering requirement, covered below.

Is there a Booming Slots welcome bonus code?
You do not need a Booming Slots welcome bonus code. The bonus appears in your account when your first deposit of £10 or more clears. If a site offers you a Booming Slots welcome code for a fee, walk away.
Wagering requirements and bet limits
A 10x wagering requirement applies to the bonus. A £25 bonus means £250 in slot bets before you can withdraw anything it produces. Free spin winnings have their own 10x requirement, so £8 won on the spins needs £80 in slot bets.
Slots count toward both requirements. Roulette, blackjack and live casino tables add nothing.
You have 30 days to finish. While you wager, your maximum bet is 10% of your bonus and free spin winnings (minimum £0.10) or £5, whichever is lower. On a £25 bonus, that puts your cap at £2.50 a spin.
You cannot withdraw the bonus money itself. Winnings from bonus play become withdrawable after you clear the requirements.
Paying in from the UK
Open the Booming Slots cashier to see which of Visa and Mastercard debit, PayPal, Pay by Phone and Open Banking transfers it accepts. The UKGC has banned credit cards for gambling since 2020, so a credit card deposit will fail. Read the Booming Slots bonus policy for any payment method that does not qualify for the new customer offer.
Play within your limits
You must be 18 or older to claim the bonus. Check the site footer for the Booming Slots UKGC licence number, and set a deposit limit before you accept the offer. BeGambleAware provides free support, and GamStop lets you block every UK-licensed gambling site at once if you need a break. Bonuses do not change your odds. Spin results are random. T&Cs apply.
