Provably fair

Every result in Tigrabit Originals comes from our server seed, your client seed and a bet number (nonce). You can check every bet yourself, and nobody, not even us, can change a result after you bet.

1We lock our seedBefore you bet, we hash our server seed and show you the hash.
2You add your seedYour client seed goes into every result. Change it any time.
3Each bet gets a numberThe nonce goes up by 1 with every bet you place.
4The result is calculatedHMAC-SHA256 mixes the seeds and the nonce into the result.
5You check itRotate your seeds to see our real seed, then verify any bet.

The math is standard HMAC-SHA256, the same as Stake's. Run these lines in Node.js to check any result without our site.

const { createHmac } = require("crypto");const b = createHmac("sha256", serverSeed)  .update(`${clientSeed}:${nonce}:0`)  .digest();const float = b[0] / 256 + b[1] / 256 ** 2  + b[2] / 256 ** 3 + b[3] / 256 ** 4;// dice: Math.floor(float * 10001) / 100

How it works

Questions

Does provably fair change my odds?
No. It proves that nobody changed the result after you bet. The house edge of each game is on its page.
Why must I rotate my seeds to verify a bet?
Your active server seed stays secret, because with it you could work out your next results. When you rotate, we show the old server seed, and you can check every bet you made with it.
Can I verify a Fun play bet?
Yes. Fun play has its own seed pair. Rotate it in the fairness settings of a game in Fun play, then paste the revealed seed in Verify a bet.
Which games are provably fair?
Every Tigrabit Original: Dice, Limbo, Mines, Plinko, Keno, Flip, Dragon Tower, Blackjack, Baccarat, Hi-Lo, Scratch, Roulette and Wheel. Slots and live casino games come from their providers.
