Each game in an online casino has its own “weight” assigned – the percentage it contributes to fulfilling wagering requirements. This assigned percentage differs in each new online casino with no deposit bonus as it depends on the casino’s unique RTP (return-to-player percentage) featured for every casino game. The rule of a thumb is that the higher the RTP is, the lower would be the wagering percentage. This happens because casinos are a business that is designed to generate revenue. And if a game with RTP of 97% like roulette would have the same wagering percentage, then bettors would fulfill the wagering requirements fast while also winning on most of their bets. As a result, the casino would lose majorly. So wagering percentage differs in order to keep the casino winning while also allowing players to have fun and get a small percentage of requirements fulfilled in the meantime.
