Which Slot Has The Highest RTP?

Some have higher 3D graphics, progressive jackpots, more bonuses, while others have a higher Return-to-Player (RTP). In this piece, we will focus on online slots with the highest RTP.

RTP just like progressive jackpots is one of the main features online casino enthusiasts look out for in a slot machine before they play with real money. This is to ensure that casino gamers can enjoy higher returns from their investment in the slot machine.

Although many online slot games in the market are developed to have high RTPs, some have amazing RTPs that beat the industry standard.

This certainly needs little explanation since a large percentage of online casino gamers are attracted by the prospect of increased profitability.

If you are looking forward to playing high RTP slots, then you are enjoined to continue reading as we will touch on some of the favourite slot machines with the highest RTPs in the casino industry.

How RTP is Calculated

RTP is the abbreviation for Return-to-Player, and it theoretically means the amount of money you can win on a wager when you play an online slot game over a period of time. For example, if a slot machine has an RTP of 95% it means that in theory, you will get back 95% of the bet you wager on the slot after playing several rounds.

On average, online slot machines usually have between 94- 96% RTPs. In view of this, any slot machine with an RTP lower than the average 94% is considered a low RTP slot. Typically, high RTP slots have between 97%-98% while very few slot machines have tantalizing RTPs of 99%.

Because we care about your gaming experience, we have taken the trouble of searching for the online slots with the highest RTPs and listed them below for your online casino gaming pleasure.
