Operator T&Cs snapshot

Captured by our editors at time of listing. Operators can change terms without notice — always verify on the live operator page before claiming.

Available to new customers only, aged 18+, located in Great Britain. You must opt in to the offer during or immediately after registration. Make a minimum first deposit of £30 via debit card or instant bank transfer only (credit cards, Apple Pay, PayPal, Paysafecard, Skrill and Neteller do not qualify). Stake a minimum of £30 on casino slots to trigger the reward. 300 Free Spins, each worth £0.10, will be credited to your account on Big Bass Splash by 5 pm the following day. Free spins expire within 48 hours of being credited. The qualifying £30 stake must be placed on casino slots only — staking on Live Casino, Table Games, Sportsbook or Racing is prohibited and will result in the cancellation of any associated winnings, exclusion from future promotions, or account closure. Winnings from Free Spins are credited to a Bonus Balance and are not withdrawable as cash. All free-spin winnings are subject to 10x wagering before becoming withdrawable. Wagering contributions: slots 100%, table games 10%. During wagering, bets must not exceed 30% of the initial bonus amount per game round, and slot stakes must not exceed £15 per spin while using bonus funds. The promotion must be opted into within 7 days of registration; the full offer (including staking requirement) expires 30 days after opt-in. Free-spin winnings must be wagered within 30 days of the spins being credited; unused bonus funds and associated winnings are forfeited after this period. One bonus per customer, IP address, device, family, household address, phone number, payment card or e-payment account. Unibet's Standard Terms and Conditions also apply. 18+ | GambleAware.org.

Bonus terms — fairness check

Fair terms

No high-risk clauses flagged in the terms we hold — standard, player-friendly wording.

Auto-flagged from the operator's own bonus terms (quoted verbatim) — not legal advice. No flag means our checks found none in the terms we hold, not that the terms are perfect. Always read the full T&Cs.
