Probability Breakdown
You set a target number (1–99). A random float is generated and scaled to 0–99.99. If the roll beats your target (over/under depending on mode), you win. The multiplier is 0.97 / (win_probability / 100). At 50% win chance: multiplier = 0.97/0.50 = 1.94x. At 1% win chance: multiplier = 97x.
House Edge Explained
Dice has a 3.0% house edge (97.0% RTP). The multiplier formula directly encodes this: multiplier = 0.97 / win_probability. At any win chance setting, your expected value per roll is exactly 97% of your bet. The house edge is constant regardless of your chosen probability.
What Does This Mean for You?
With an RTP of 97.0%, for every 100 coins you wager on Dice, you can expect to get back approximately 97.0 coins over thousands of rounds. The remaining 3.0% goes to the house.
This is a long-run average. In any single session, your results will vary wildly — that's the variance (volatility: Low). Short sessions can see 50%+ swings in either direction. The RTP only converges over thousands of rounds.
