How it works

You vs another player. Pick a side. Flip.

  1. 01

    Choose your stake

    Pick an amount of FunBucks and a side: HEADS (GET RICH) or TAILS (GET BROKE).

  2. 02

    Another player joins

    Someone takes the opposite side and matches your stake. No house, just you vs them.

  3. 03

    The coin flips

    The result is locked in by the fairness engine. Winner takes the pot minus the platform fee.

Provably fair

Every flip uses a verifiable fairness system.

Before the flip, BrokeFlips commits to a secret server seed by publishing its hash. After the flip, the seed is revealed. Because the original hash matches, the server cannot secretly change the seed after seeing the result.

Verify a flip yourself →
  1. 1. Commit

    hash = SHA-256(serverSeed)

    published before anyone joins

  2. 2. Contribute

    clientSeed = creatorSeed : opponentSeed

    both players add randomness

  3. 3. Derive

    HMAC-SHA256(serverSeed, clientSeed:nonce:gameId)

    first 4 bytes mod 2 → HEADS / TAILS

  4. 4. Reveal

    serverSeed published

    anyone can recompute the result
