A cashback bonus is a type of online casino bonus that rewards players with a percentage of their total losses incurred. Players who opt to take a cashback bonus will receive a certain percentage of their net losses back as bonus money. For instance, if the cashback bonus offers a 20% return, a player who lost ā¬200 (accumulated from multiple game rounds) will receive ā¬40 back in bonus money. When using this bonus, it is important for players to read the terms and conditions carefully to understand the exact conditions of the promotion as many online casinos have different standards and requirements.
