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.

Offer available to new GB customers aged 18 and over only. Opt in is required. Deposit and stake a minimum of £30 on casino slots via debit card or instant bank transfer only (credit cards, Apple Pay, PayPal, Paysafe Cards, Skrill and Neteller do not qualify). Once the £30 qualifying stake on slots is met, 300 free spins (each valued at £0.10) will be credited to your account for use on Big Bass Splash; spins will be credited by 5 pm the following day. Free spins must be claimed within 7 days of opting in; the promotion expires 30 days after opt-in. Free spins expire within 48 hours of being credited. Free spin winnings are subject to 10× wagering before becoming withdrawable; wagering must be completed within 30 days of the spins being credited. Wagering is valid on slot games only (100% contribution); table games contribute 10%. Maximum stake during wagering is £15 per spin. The qualifying £30 stake may only be placed on casino slots — staking on live casino, table games, sportsbook or racing is prohibited and may result in cancellation of winnings, exclusion from future promotions or account closure. Free spins cannot be withdrawn as cash. Bonus funds are credited to the Bonus Balance and cannot be used on products other than casino slots. This promotion is available once per customer, IP address, device, household and payment method. Full Unibet Standard Terms and Conditions also apply.

Check.casino bonus score

Good welcome bonus. 10× wagering on winnings is the standout. The main catch: £30 to qualify.

  • Wagering: 10× wagering on winnings
  • Value: Up to £20 + 300 spins
  • Validity: 30 days to use it
  • Min deposit: £30 to qualify
  • Max bet: £15 max bet while wagering

A fixed formula on this offer's verified terms — wagering (38%), value (26%), validity, min deposit & max bet — not an opinion. Always confirm the current terms with the operator before claiming.

Bonus terms — fairness check

Mostly fair

Common restrictive clauses apply (max-bet rule while wagering) — standard for the UK market, flagged here for transparency.

  • moderateMax-bet rule while wagering
    “Maximum stake during wagering is £15 per spin.”

    Bet above the per-spin cap while wagering and the bonus + any winnings can be removed — easy to trip by accident.
