Legal in Virginia There are thousands of online slots available at US online casinos. Some of these online casino slot games are better than others. It all comes down to return-to-player (RTP). High RTP slots pay out more often than other types of slot machine. In this article, BonusFinder US lists the top 10 high RTP slot game options at US online casinos.
The highest RTP slots have more than 98% return to player
Online casino slot machines are numbered in the thousands. Therefore, finding the real money slots games that pay the best is crucial, especially if you are trying to play through your bonus money. This means that you need to look for best RTP slots. They are slot machines that give you the best chance to win in the long run.
RTP stands for return to player and is the single most important metric when playing online slots. It marks the average return to player in the long run, which means that high RTP slots are more profitable for casino players (and less profitable for the online casino sites because of the lower house edge) They are also exceptionally important when trying to get rid of the wagering requirements for your casino bonuses.
Note that the RTP percentage of an online slot game is a long-time average. With a 98% RTP slot, you would win on average $98 for every $100 you wager. The average is calculated with thousands of spins, so in real life, you could lose 20 spins in a row, and lose $100 and not win cash prizes. This is called volatility or variance.
Volatility or variance indicates how often and how big an online slot is going to pay out. High volatility slots pay out rarely, but big, and low volatility slots give out small wins relatively often. Most high RTP slots are also high variance slots, because the high RTP is due to massive wins from bonuses or jackpots. Because progressive jackpots can’t be calculated accurately, they are usually excluded from best RTP slots lists.

However, with such high payout percentages, we assume that some of them will be excluded from welcome bonus offers.
Ugga Bugga is the highest payout online slot machine in the world. This PlayTech slot game has 99.07% RTP, meaning that the online casino sites house edge is less than 1%. No other slot machines have RTP of more than 99%. Even online slots with 98% RTP are rare. With the max bet, you can win up to $50,000, which is 1,000x the $50 max bet.
The NetEnt classic has a 99% RTP meaning that the house edge is only 1%. This rivals most table games and video poker game options. Because the game has high volatility, it’s not guaranteed to always pay out, but when it does, the max win in Mega Joker is 2,000x your stake with the Supermeter bonus game. However, don’t think you can play Mega Joker with your welcome bonus money. No online casino in their right mind would feature this Mega Joker slot game for bonuses, especially because the game features a progressive jackpot on top of the high RTP!
Book of 99 is another 99% RTP slot game. It’s one of the three second highest payout online slot machines in the world. With a 1% house edge, the Book of 99 is never featured in welcome bonus lists, and the 5,000x max win makes it a really risky game for casinos. This Relax Gaming hit is one we don’t think might be available in the US for quite a while.
Ooh Aah Dracula is the third slot with 99% RTP. Theoretically, this Barcrest product could be available in the US, but no online casinos have added it to their catalog yet. The 99% RTP rivals most casino games, which makes Ooh Aah Dracula an exciting prospect when it enters the US market.
