Prism Casino offers a 480% deposit bonus when you use the code FRIGHTNIGHT at the cashier. The match scales with the deposit: $30 gets 280%, $60 gets 380%; $90 gets the full 480%.
The minimum deposit is $30. The bonus can be redeemed 4 times. It applies to keno and slots.
No wagering requirements apply, and there's no maximum cashout limit. The bonus amount itself isn't cashable.
The offer is open to all players and runs until 2026-10-31. It suits players who deposit at least $30 and want extra playing funds on keno or slots without a playthrough condition.
