Fairness
A revealed server seed does not just prove the bets you already made were fair — it fixes every bet that seed could ever produce. Build the exact board you play and this walks the seed bet by bet: which nonces your board wins on, how far the next one is, how many there are, and how long the dry runs get.
Add a server seed and client seed above — or hit Try a random seed.

Once a server seed is revealed, every outcome it will ever produce is already fixed. This walks the seed bet by bet and shows exactly which nonces your board would have won on — the next one, how many there are, and how long the dry spells run.
Nothing is uploaded. The scan runs in your browser, on your machine, split across your CPU cores.
Enter a nonce to see the exact board that bet produced — or tap one of the winning nonces above.
YEET generates each bet with HMAC-SHA256(serverSeed, clientSeed:nonce:round), then reads the digest four bytes at a time into floats between 0 and 1. Those floats become your dice roll, your multiplier, your board.
Because the nonce is just a counter, the whole future of a seed is computable the moment the seed is revealed — which is exactly what the commitment is meant to guarantee.
Dice, Limbo and Coin Flip use the conversion YEET publishes, so those are exact.
Keno and Mines are rebuilt. YEET publishes the random stream but not the shuffle that turns it into a board, so this uses the standard Fisher-Yates construction. The odds are exact either way — any uniform shuffle gives identical probabilities — but the specific board shown for a specific nonce depends on that shuffle being right. Replay a bet you actually placed to confirm it before trusting a board.
The scan runs on your own machine, split across your CPU cores. Your seeds are never sent anywhere, never logged and never stored — a fairness tool you have to trust someone's backend for is not much of a fairness tool.
Only paste a server seed that has already been rotated and revealed. A live seed is supposed to stay secret until you rotate it.
Finding a big win sitting on a nonce you already passed does not mean you missed anything, and rotating a seed cannot move you closer to one. Every bet is drawn independently, so a seed is not a map with treasure buried at fixed spots — it only looks that way in hindsight, once the seed is revealed and the outcomes stop being random to you.
What seed rotation genuinely does is protect you. The operator picks the server seed knowing your current client seed, so changing your client seed after they commit is what stops a seed from being chosen against you. That is worth doing. Chasing a nonce is not.
