New GB customers only. 18+. Opt-in required. Deposit and stake a minimum of £30 on casino slots using a debit card or instant bank transfer (other payment methods do not qualify) to receive 300 free spins (each worth £0.10) on Big Bass Splash. The offer must be opted into and the qualifying deposit and stake completed within 7 days of registration. Free spins are credited to your Bonus Balance and expire within 48 hours of being issued; unused free spins are forfeited. Free spins cannot be withdrawn as cash. Winnings from free spins are subject to a 10× wagering requirement, which must be completed within 30 days of the free spins being credited; failure to complete wagering within this period will result in the forfeiture of any remaining bonus funds and associated winnings. The bonus may only be used and wagered on casino slots; using it on the sportsbook, racing, or any other product is prohibited and will result in the cancellation of any winnings derived from bonus funds, exclusion from future promotions, or account closure.

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
Some concerns2 clauses worth reading carefully before you claim, including discretionary wording that can affect payouts.
- serious"Irregular play" clause
“Unibet reserves the right to withhold, restrict, or cancel this promotion and reclaim any bonus funds or winnings in cases of bonus abuse.”
Vague "irregular / low-risk play" wording lets the operator void winnings at its discretion — one of the most player-unfriendly bonus terms.
- moderateMax-bet rule while wagering
“Game contribution rates and maximum stake limits apply during wagering.”
Bet above the per-spin cap while wagering and the bonus + any winnings can be removed — easy to trip by accident.
