How Crypto Dice Works
Dice is the simplest provably fair crypto casino game. A random number between 0.00 and 100.00 is generated, and you bet whether the result will be over or under your chosen target. The payout multiplier is calculated automatically based on your win probability.
The Math Behind Dice
Stake.com uses a straightforward formula with a 1% house edge:
Multiplier = 0.99 / Win Chance
Example: Roll Over 50.00
Win Chance = 50.00% (50/100)
Multiplier = 0.99 / 0.50 = 1.98x
Example: Roll Over 90.00
Win Chance = 10.00% (10/100)
Multiplier = 0.99 / 0.10 = 9.90x
Example: Roll Under 10.00
Win Chance = 10.00% (10/100)
Multiplier = 0.99 / 0.10 = 9.90x
Provably Fair Verification
Each dice roll is generated using HMAC_SHA256 with a server seed, client seed, and nonce. The 32-byte hash output is converted to a float between 0 and 1, then mapped to the 0.00–100.00 roll range using: floor(float × 10001) / 100. This produces a uniform distribution with exactly 10,001 possible outcomes.
Key Dice Strategies
Low Risk (70-80% Win Chance)
Set target to ~25 (Roll Over) for ~75% win chance at ~1.32x multiplier. Small, consistent wins but still loses 1% over time.
Medium Risk (45-55% Win Chance)
Roll Over 50 gives 50% win chance at 1.98x. Most balanced risk/reward ratio.
High Risk (5-15% Win Chance)
Roll Over 90 gives 10% win chance at 9.9x. High volatility — big wins are rare but significant. Bankroll management is critical.
Dice vs Crash
Both games have a 1% house edge, but Dice offers more control. You choose your exact win probability and multiplier, while in Crash you only set your cashout target. Dice is ideal for systematic strategies like Martingale because you can precisely calibrate your win chance for each bet.
