Grosvenor Casinos
Grosvenor pairs a £40 bonus with 100 Big Bass Splash spins after a £20 deposit. The cash bonus needs £600 of eligible turnover, and both rewards have separate winnings caps, so they should be valued separately.

How the selected offer works
A £20 first deposit after selecting the offer in the cashier produces £40 bonus credit and 100 ten-pence spins on Big Bass Splash. The two rewards are governed by separate conditions.
The condition that changes the value
The cash bonus requires ten times the £20 deposit plus £40 bonus, or £600 in eligible stakes, within 30 days. Only up to £200 can convert to cash. Winnings from the spins are bonus funds requiring ten-times wagering within seven days and capped at £100 conversion.
Deposits and withdrawals
Visa and Mastercard debit, PayPal, Apple Pay and Instant Bank Transfer support deposits and withdrawals. Paysafecard is deposit-only, and a first deposit through PayPal or Paysafecard will not unlock this welcome package.
What you can play
Grosvenor has slots, live casino, tables and poker. Bonus contribution differs across game groups; the listed selected slots are the main route to full contribution.
