Every published number here is the number the game engine actually uses — not a marketing rounding of it.
All six Overdrive categories have a 4% house edge (96% theoretical return). The 50 sectors are equally likely. Multipliers include the stake; an unmatched category returns zero. Stake limits are 0.01–1,000,000 units and the maximum result is 384×, with exact integer payouts.
Each round publishes its own SHA-256 seed commitment before the bet. HMAC-SHA256 with rejection sampling determines the main wheel and bonus draws. The seed is revealed after all bonus choices are final. Open a recent round on the Overdrive page to check its commitment, choices and payout in the browser verifier. Overdrive runs shared server rounds. Matching bettors vote on each bonus stage; majority wins and committed draws break ties. Bonuses and payouts continue when you disconnect. Reconnecting resumes the shared timeline.
Crash, Double, Upgrader, Plinko and Defuse accept stakes from 0.01 to 1,000,000 units. Payouts round down to 0.001 units. Upgrader, Plinko and Defuse have a maximum payout is 1,000,000,000 units. Rounding, the payout cap and Upgrader's 80% chance ceiling can increase the effective house edge. Upgrader chances round down to 0.01%.

Double commits a private server seed by its SHA-256 hash before accepting bets. The server keeps the seed private until settlement. Verify the revealed seed against that commitment, then recompute the result using the client seed and nonce 0. Legacy rounds may display an EOS key.

Each round reveals a preimage of the previous revealed hash. For a chain's first round, SHA256(revealed hash) must equal its published commitment. Private checkpoints are never published. Bitcoin reference metadata does not determine the chain. The server knows upcoming outcomes; the commitment enables verification after play, not independent external randomness.

Paste a revealed server seed (only available after a round settles or a seed is rotated), the client seed, the nonce, and the modulus (total odds weight for a case; 10000 for the upgrader; 15 for Double) to recompute the exact result yourself.
Paste a revealed round's chain hash and client seed (from the table above) to recompute its exact crash point yourself, at Crash's published 5% house edge.
