Plinko
Drop a ball through a triangular field of pegs. Each bucket at the bottom pays its own multiplier - the higher the risk tier, the wider the spread between center and edges.
Play PlinkoAbout
Plinko is a path-randomized payout game. You pick row count (8-16) and risk (low / medium / high), then drop a ball; it bounces left or right at each peg until it lands in one of N+1 buckets, each carrying its own pre-published multiplier.
How a round plays
- Pick row count between 8 and 16 and a risk tier.
- Place your bet; the bucket multipliers are published before the drop.
- The ball bounces L or R at each peg, derived deterministically from the seed pair plus the round nonce.
- It lands in one bucket; the multiplier on that bucket determines the payout.
Provably fair
- The L/R bounce sequence is read from HMAC-SHA256(server_seed, client_seed || nonce) - fixed before the ball drops.
- Server seed is committed before the round, revealed after you rotate.
- After rotation, the verifier reproduces the exact bounce path from your seed pair + nonce.
Every round is verifiable from a server seed (revealed after rotation), your client seed, and a per-round nonce. See how it works for the full construction.
