Top 10 slots with the highest RTP of all time

Online slots come in many colours and flavours. Most have a specific theme, some have great soundtracks, and hey, they offer great wins too. In fact, most players will only care about the statistics of a game and won’t be bothered with other features, which brings us to today’s guide on the highest percentage payout slot machines.

There are several factors to consider when you’re looking for high potential slot games, but one of the most important things to take into consideration is the Return To Player (RTP): the payout percentage. Luckily, it doesn’t require any special skills to understand what this stands for, so after introducing you to the concept of RTP we will directly get to the point and give you the 10 slots with the highest RTP of all time. Let’s go. 

Return to Player (RTP) explained

The Return to Player is also referred to as the payout percentage or the RTP to keep things simple. The RTP is the average payout of an online casino game over a large number of spins expressed in a percentage. The basic idea of this concept is very easy: the higher this percentage, the more you should win over a longer period of time. 

RTP vs. House Edge

For example, a game with an RTP of 96% returns 0,96 cents for each $1 bet or $960 for each $1000 wagered on that particular title. The important thing to point out here is that this is only an average percentage and differences can occur in the short term, which is actually what makes online betting so much fun. A closely related definition is that of the house edge. The RTP is actually the opposite of the house edge, e.g. the profit that the (online) casino takes. If you know the game’s RTP, you can easily calculate the house edge and vice versa. In the same example of 96% RTP, the house edge is 4%. With every $1 bet, 4 cents is earned by the house, the casino. This advantage will make sense to most people as it’s the casino offering the game and making sure everyone feels welcome. Ideally, you would need to stick to games with a high RTP and a low house edge.

Above average RTP slots

Although there are many different slots available for Canadian users and there are different RTP’s, most slot games work with percentages between 96% and 97%. Every now and then we come across titles that have either higher or lower Return to Player’s and while a difference of a few percentage points doesn’t seem like a big deal, it does actually affect net revenues once you play more often. This is exactly why we’ve listed games with exceptionally high RTP’s to give you nothing but the best RTP options on the market.
