The so-called Max Bet Rule applies in most online casinos during an active bonus phase. Here, a Maximum bet (= Max Bet) is prescribed, which may be used with the credited bonus credit per game round at the most. Often, a Max Bet Rule in the amount of five euros per spin applies.
If players disregard the Max Bet Rule and wager a higher amount, the Online Casino will cancel the resulting wins and refuse a payout. In addition, in this case, the credited bonus amount will also be canceled again, since the valid bonus conditions were violated. Partly, the online casinos warn the players with a corresponding message about the Max Bet Rule. However, players should not necessarily rely on this. Normally, users can find relevant details about the Max Bet Rule either in the Bonus terms and conditions or in the General Terms and Conditions (GTC) of the respective online casino.
The online casinos often work with such a Max Bet Rule to protect themselves against unexpectedly high wins of the players. If, for example, a bonus user wagers ten or twenty euros in bonus credit in a game round and wins, then high winnings payouts would be the result - an expensive undertaking for the casino. Those who do not wish to adhere to a Max Bet Rule must generally refrain from claiming a Casino bonus.
