What Is RTP?
RTP stands for Return to Player.
It is expressed as a percentage and represents the average long term return a game is mathematically designed to give back to players.
Example:
A game with 97 percent RTP is expected to return an average of 97 for every 100 wagered over a very large number of plays.
RTP Is Long Term Only
RTP is calculated over millions of rounds.
This means:
• You can win far more than expected in a short session
• You can lose faster than expected
• RTP describes long term performance, not short term results
RTP Exists Across All Casino Games
Many players think RTP is only for slots, but it applies to almost every casino game type.
Here are examples:
• Blackjack often has the highest RTP when played with optimal strategy
• Roulette has fixed RTP depending on the wheel type
• Crash games display RTP through multiplier probability curves
• Provably fair games publish transparent house edges
• Video poker offers some of the highest RTP values in the industry
• Slots vary widely depending on design and provider
Crypto casinos often show the RTP clearly, especially when the game uses on chain verification or provably fair mechanics.
What Is Variance
Variance describes the risk pattern of a casino game. It shows how often wins occur and how large those wins tend to be.
Variance is also used in non slot games, although players notice it more clearly in slots and crash titles.
Low Variance
• Frequent wins
• Small or moderate payouts
• Smooth gameplay
• Predictable bankroll behavior
• Great for beginners or for clearing bonuses
Typical low variance examples:
Certain blackjack variants, some video poker games, many provably fair titles.
Medium Variance
• Balanced win frequency
• Balanced payout size
• Suitable for most players
• Good for casual sessions
Typical medium variance examples:
Standard roulette play, many popular slots, various crypto crash games.
High Variance
• Rare wins
• Large payout potential
• Sharp swings in bankroll
• Best for players who accept risk and chase larger results
Typical high variance examples:
Certain jackpot slots, high multiplier crash games, specialty titles with extreme risk curves.
How RTP and Variance Work Together
RTP tells you the long term expected return.
Variance tells you how smooth or unstable the journey will be.
Examples:
High RTP and Low Variance
• Consistent returns
• Slow and controlled gameplay
• Ideal for long sessions or wagering requirements
High RTP and High Variance
• Strong long term value
• Huge potential payouts
• Wild short term swings
Low RTP and High Variance
• High risk
• Rare wins
• Only worth playing in specific bonus situations or promotions
Low RTP and Low Variance
• Frequent small payouts
• Limited long term potential
• Not usually optimal for serious players
