The cashback rate depends on how much a player has bet on slot games during the week. Only the player’s own money that was lost from their real balance is counted when calculating the cashback.
From Copper to Diamond levels, cashback is calculated only from the total amount of losing bets. But once you reach VIP status, it’s calculated from all bets you make, and the exact cashback rate depends on the game type.
If there’s any suspicion of rule violations or creating fake accounts or gaming groups, the company has the right to cancel any bonuses and winnings on those accounts and to close the accounts entirely.
