How the House Edge Works
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 This Means in Practice
If you wager 10,000 coins on Dice over a session, the math says you'll get back approximately 9,700 coins and lose about 300 coins. But this is a long-run average.
In reality, short sessions are dominated by variance. You might win big in 20 rounds or go on a losing streak. The house edge only converges over thousands of rounds — that's the law of large numbers at work.
The key insight: the house edge is not your enemy per round. It's the cost of entertainment over time. Playing with awareness of the math lets you budget accordingly.

Why Transparency Matters
Most online casinos don't publish their exact house edge formulas. At Rookie, the math is public. Every outcome is provably fair — generated from HMAC-SHA256 cryptography that you can verify independently. The house edge is encoded in the payout formulas, which are open for inspection.
This means you can calculate expected value for any bet, verify any past result, and trust that the stated RTP is accurate. No hidden variables, no server-side manipulation.
