So, which online slots have the highest RTP rates, and which online casinos host these slots? BetMGM, Caesars Palace, DraftKings, Golden Nugget, and Borgata all have slots with RTP in the 97% to 99% range, which is as good as it gets.

Casino games are for entertainment, and their payouts are random, so there's no specific time of the day or week where you'll experience more wins.
