What is RTP & why do you need to know about it?

RTP, or Return To Player, is the percentage of the money you get back from the money wagered during the game of your choice. It’s crucial when searching for the best RTP slots because they offer higher returns.

We’ve shown you the best RTP slots with the highest RTP percentages, but now you need to dive deeper into understanding them. You can find the RTP of a slot on the slot itself while playing one of the best RTP slots! All you need to do is head over to the information section or the settings (depending on your slot).

There, you’ll find the RTP percentage of the game, along with other important information. You can sometimes also check out the RTP by hovering over the logo of the game when browsing the game library of your online casino in Ontario, particularly when looking for the best RTP slots.

What’s the difference between RTP and Volatility

But wait! Does high volatility mean the same as high RTP?

Nope. Hold your horses. High volatility slots have a lesser chance of providing you with potential combinations when you spin. EVEN IF your slot has a high RTP, your chances of winning can be radically different when playing a high volatility slot. The bottom line is that these types of slots have larger prizes but low chances of winning. 

If you choose a slot with high RTP and low-medium volatility, your chances of winning get upped because more winning combinations can show up on your screen. With the RTP being high, that means you can get more of what you wagered in return.
