Looking for high-RTP slots? We’ve got them

We love online slots. We really do. However, not all slots are created equal.

Some are more equal than others, so to speak. What are we talking about?

The Return to Player of slots and how, excuse our French, millions of players are getting screwed by online casinos. Why? Because casinos can offer players the same slot at several different RTP (Return To Player) levels.

While one slot can pay back 96% at online casino A, the same slot can pay back only 88% at online casino B.

So, are you playing on the highest possible version right now? Let us guide you toward the highest-payout slots and only the best high-RTP online casinos.

Tips and frequently asked questions

What does Return to Player (RTP) mean, and how is it calculated?

The Return To Player is a percentage that shows how much the slot pays back to the player. The RTP is calculated over billions of spins and is always an average. The RTP also defines the online casinos' long-term win margin on a specific slot. The RTP percentage of each slot can be found in the slots info section or game rules.

What are high RTP slots?

A high RTP slot is a slot that is played at the highest possible Return To Player level. This RTP is sometimes called the default RTP. While some online casinos offer high RTP slots, many of them don't. The trick is to find a casino that does. Hint: we can help you with that.

Why is the RTP of a slot so important?

Game providers like Nolimit City, Play'n GO, Hacksaw Gaming, Relax Gaming, NetEnt, Red Tiger, Pragmatic Play, and many more create slots with various RTP versions due to increased demand from casino sites/operators.
