People love online slots and think it’s all about the lights, sounds, and potential winnings. But there’s fascinating math, and more importantly, there’s a fascinating math term called RTP.
RTP stands for Return to Player. This number helps players determine what percentage of a given slot will pay out over a long period of time. The higher the percentage, the better the jackpot odds will be over a long period. Most slots will pay out on average of about 95%. However, players can find slots that pay out over 97%. These slots offer a more enjoyable gaming experience. Let’s take a look at the highest RTP online slots.
Top High RTP Online Slots
Here are some of the most respected high RTP slots.
Mega Joker (NetEnt) – 99% RTP
If you like things simple, Mega Joker is a good option. Designed by NetEnt, this classic fruit machine is simple, but it has a lot of potential. The old-school design is a nostalgic reminder of land-based casinos, filled with cherries, lemons, bells, and jokers spinning on the classic reels.
The Supermeter mode makes it even more exciting, as you can take larger risks for larger rewards. Add a progressive jackpot, and Mega Joker becomes an exciting combination of simplicity and strategy. This game is meant for players who prefer rapid play and like to see the cash potential.
Ugga Bugga (Playtech) – 99.07% RTP
Ugga Bugga by Playtech turns a slot machine on its head. Instead of the traditional spinning reels, it has a strange configuration that feels like a mash-up of a slot machine and a strategy game. Every spin is accompanied by opportunities to win, as players can “hold” certain symbols and respin the rest.
The control players have during the game, combined with the ability to customize their strategy, creates very addictive gameplay. Ugga Bugga is tribal themed, which is very primitive and pseudo-African. Ugga Bugga has a very tribal rhythm to it, and a 99.07% RTP is very impressive, and it is one of the best Ugga Bugga RTPs for players looking for remarkable RTP.
