Step-by-Step Guide

- 2
Optionally stack multiple flips — predict the outcome of 1–10 consecutive flips.
- 3
Set your bet amount and click Flip.
- 4
The coin flips once (or multiple times for stacked bets).
- 5
If all your predictions are correct, you win bet × multiplier. One wrong call loses the bet.
Provably Fair System
Each flip result is a single bit from HMAC-SHA256(server_seed, client_seed:nonce). Bit = 0 is Heads, bit = 1 is Tails. For stacked flips, consecutive bits from the same hash determine each flip. Verification is trivial — one hash, read the bits.
Visit the Fairness Verification page to verify any past round with your seeds.
