1. What Is RTP?

Return to Player, or RTP in gambling, is a theoretical percentage showing how much a game returns to players over time. Calculated across millions of spins, it guides expectations, although individual sessions may vary.

2. How Is RTP Calculated?

If you’ve ever questioned, “How does RTP work in gambling, and how is it calculated?” the UKGC offers a comprehensive guide on How to Calculate Return to Player. The basic formula involves dividing total winnings by total bets.

3. Theoretical RTP vs. Actual RTP

So, there’s theoretical RTP, meaning the average payout calculated from millions of spins. Then there’s your actual RTP in a single session, which can be wildly different due to luck and game variance, which we’ve explained later.

4. What’s a Good RTP Percentage?

The notion of a “good” RTP percentage varies depending on the game, but here’s a general guide: aim for higher RTPs when possible. For instance, steer clear of slots with an RTP of 85%, as that’s quite low.

Casino Game Optimal RTP Range
Slots 92% – 98%
Progressive Jackpot (PJP) Slots 85% – 94%
Blackjack 98% – 99.5%
European Roulette 97.3% (fixed due to its single-zero wheel)
American Roulette 94.7% (fixed due to an additional 00 pocket)
French Roulette 97.30% (Inside bets) – 98.65% (Even money bets)
Baccarat 85% (Tie bets) – 98.94% (Banker bets)
Craps 90% (other bets) – 98.64% (Pass/Come bets)
Video Poker 95% – 99%

5. Bonus Rounds Come with a Different RTP

Did you know that bonus rounds in many casino games have their own RTP? That’s right, the return to player percentage can change during these special features, so manage your expectations accordingly.

6. Progressive Jackpots: Why the RTP Is Lower

Ever wonder why progressive jackpot slots have lower RTP? That’s primarily because a portion of each bet contributes to the growing progressive jackpot, leaving less money available for regular payouts.

Slot Game Total RTP Base Game RTP Progressive Jackpot Contribution
Mega Moolah 96.67% 88.12% 8.80%
Mega Fortune 96.60% 89.21% 7.39%
Fishin’ Frenzy Jackpot 95.64% 93.32% 2.32%
Hall of Gods 95.30% 89.40% 5.90%
Divine Fortune 96.59% 92.52% 4.07%

7. RTP vs. House Edge

RTP represents the percentage of wagers returned to players, while the house edge is the casino’s profit margin. Together, they add up to 100%, balancing player returns and casino earnings.

8. Does High RTP Guarantee Wins?

Not so fast! A high RTP indicates a greater return to players over many plays. It doesn’t guarantee individual wins – short-term results are still subject to chance.

9. The RTP of a Game Is Static

RTP is set in stone as it’s calculated and tested before launch. Yet, your session’s RTP can vary due to luck and game variance. While the official RTP remains constant, your individual session results will fluctuate.

10. Should RTP Affect Your Strategy?

Higher RTP games can offer better long-term prospects. At the same time, short-term results are influenced by variance, making it essential to balance RTP considerations with an understanding of game dynamics.

Our Expert’s Advice

“While strategies can’t boost odds in games of chance, choosing online slots can be wiser due to higher RTPs, often ranging from 95% to 98%, compared to 85% to 90% in land-based slots.”

11. How Variance Impacts RTP

Variance affects the frequency and size of wins. Even with a high RTP, high-variance games can be unpredictable, with fewer but larger wins. Low-variance games offer smaller, more frequent wins. Choose games that match your risk tolerance.
