Art Casino 15% Cashback Deposit Bonus

Art Casino runs a 15% Sunday Cashback offer for existing players. It covers losses on the day, worked out as total bet minus total win.

The qualifying window runs every Sunday from 00:01 GMT + 1 until 23:59 GMT + 1. Cashback lands automatically on Monday when you first log in. There's no code to enter and no claim step.

The offer stays open until 2026-10-26. It suits regular players who already have an account and want part of their Sunday losses returned. The maths is simple: total bet minus total win; that's the figure the 15% applies to.
