About Crypto Coin Flip
AlgoRoll Coin Flip is a provably fair 50/50 crypto game with a 2x payout on every win. Play PvP against other players or instantly against the house in Bot Mode. Both players' wagers are secured, and the outcome is determined by a provably fair HMAC-SHA256 commit-reveal scheme, making manipulation impossible.
Provably Fair Verification
Each coin flip result is generated using HMAC-SHA256 with a server seed committed to the Algorand blockchain before play. The server seed is revealed on-chain after the flip, so any participant can independently verify the result. In PvP mode, wagers are locked before the flip, ensuring neither player nor the platform can influence the outcome.
