What is RTP in Slots, and Why Does it Matter?
RTP refers to the Return to Player percentage. It’s the opposite of the house edge, showing how much players can expect to profit from bets over time. A high RTP offers greater odds to players, while a lower RTP means the casino has the higher advantage.
Let’s say the slot comes with 96% RTP. Theoretically, for every $100 staked on the slot, the players can receive $96 in wins. Keep in mind that this percentage is not linked to individual gameplay.
A common misconception is that if you play a slot 100 times, you’ll win 96% of the time. Instead, this simply means that there’s a better chance of winning as often as 96% of the time based on millions or billions of spins. Winning is entirely up to luck and RNG (random number generator), which ensures that the outcomes are random and fair.
Volatility vs. RTP
One thing that often tends to confuse players, especially those new to High RTP slots, is how the volatility and the RTP differ, as well as the role they play.
The volatility is an indication of how often winnings can appear and the size of those winnings. You get low, medium, and high volatility slots.
- Low Volatility: If it’s a low volatility slot, it provides more frequent payouts but of smaller size.
- Medium Volatility: These provide a mix of big and small payouts. The Best RTP slots with medium volatility are known for their balanced payouts.
- High Volatility: These slots don’t pay too frequently but award sizeable payouts that are often worth the wait.
The return to player percentage indicates how much the slot pays out over time and points you toward the slots with the best odds.
How is RTP Calculated?
RTP represents the percentage of wagered funds that the game is expected to return to its players over its lifespan. RTP is calculated using a mathematical model that defines all the possible outcomes. This includes the different symbol combinations that can appear on the reels and the frequency at which they appear.
For instance, here you can see the possible payouts that can take place when symbols land on the reels of Jack Hammer 2.
The game RTP is determined based on these combinations after all possible game outcomes have been determined. Simulations and historical data are used to see how the game performs over a large number of spins, and the calculations also consider all bonus features.
Let’s not forget the role of slot volatility, which indicates how the return is spread out throughout the game. With the timeframe taken into consideration, these calculations cover the game in its entirety rather than gameplay by a single individual.
Features of the Best RTP Slots
High RTP slots are anything but boring. You’ll notice that most of these titles have a selection of bonus features that can boost not only the enjoyment of your gameplay but also your win potential.
