To increase the chances of winning, check for betting sites with higher RTP or Return to Player percentage. A higher RTP means higher chances of winning. For casino slots, for instance, Mega Joker and Jackpot 6000 both by NetEnt, claim to have a 99% and 98.8% RTP, respectively, thereby increasing the odds of making money from casinos. Aside from RTP, check also the house edge if the odds are favorable to the house or the players.
