What Is RTP in Online Casinos and How Does It Work?

Max RTP Graph: Understanding Return Percentages in 2025
RTP, or Return to Player, is a casino metric that reflects the percentage of bets a slot machine returns to players over the long term. For example, a slot with an RTP of 97% theoretically returns $97 out of every $100 bet over millions of spins. A high RTP (96% and above) increases your chances of winning, making the game more profitable. Compare this: the Mega Joker slot with an RTP of 99% returns more than one with an 85%. In this article, we’ll explore how RTP works and give you tips on choosing the best slots and casinos. Read our guides below for more details!

How RTP works in slots

Which slots have a high RTP for successful play?

RTP (Return to Player) is a percentage return calculated based on millions of spins. It’s not a guarantee of winning in a single session, but a statistical indicator for long-term play. For example, providers like Play’n GO can offer slots with varying RTPs—from 84% to 96%, depending on the casino’s settings. Licensed platforms typically choose a high RTP to ensure fairness. Volatility is an important factor. Slots with a high RTP and low volatility, such as NetEnt’s Starburst , offer frequent, small payouts. Games with high volatility offer fewer, but larger, payouts. Knowing this will help you choose the slots that best suit your preferences.

How to choose games and casinos with high RTP

To increase your chances of winning, look for slots with an RTP of 96% or higher, such as Blood Suckers (98%) or Ugga Bugga (99.07%). Check the RTP in demo mode or on the provider’s official websites, as some casinos may use lower settings.  For example, Red Tiger slots sometimes have an effective RTP of around 75% due to large jackpots. For high stakes, there’s no point in playing Red Tiger slots.
Don’t chase slots with the highest RTP. If a slot is outdated or of low quality, you shouldn’t expect big wins. Gambler.casino experts constantly select high-quality slots with high RTPs from top providers.
We recommend playing at licensed casinos where RTP is transparent and not understated. Want to know which platforms offer the best rates? Check out our casino ratings and slot and provider guides.
