That doesn’t mean that you’re guaranteed to win on a higher RTP game. That’s because land-based casinos have much higher overhead, so they need a bigger profit margin to offset their operating costs. It’s possible to have a game with low volatility and a low RTP. That’s why a game can be both high-RTP and highly volatile; if the wins are big enough, they can offset long losing streaks. This is why RTP is a useful measure for comparing games, but it is not a predictor of what will happen in a single session. Slot RTP is calculated when software providers simulate millions of spins in order to create a useful sample size.
Every slot machine available to play via online casinos in the uk will provide details on slots RTP. Knowing a slot machine’s RTP (Return to Player) can allow you to compare games more easily and make mathematically informed decisions in terms of the slots you choose to play.
