# Verify a Gamdom bet

9 Gamdom originals can be recomputed here from their fairness details, following Gamdom's own published algorithm. Gamdom publishes no worked examples, so all of them are checked against Gamdom's own verifier code. Everything runs in your browser.

## Seed pair · 6 games, from server seed, client seed and nonce

Seed pair

| Game | Inputs | Vectors | Algorithm source |
| --- | --- | --- | --- |
| [Dice →](https://gambatracker.com/verify/gamdom/dice) | server seed, client seed, nonce + hashed server seed | casino's own code | [codesandbox.io](https://codesandbox.io/p/sandbox/gamdom-dice-hash-checker-forked-4nvt7l) |
| [Limbo →](https://gambatracker.com/verify/gamdom/limbo) | server seed, client seed, nonce + hashed server seed | casino's own code | [codesandbox.io](https://codesandbox.io/embed/tk7zct) |
| [Plinko →](https://gambatracker.com/verify/gamdom/plinko) | server seed, client seed, nonce + hashed server seed, rows, risk | casino's own code | [codesandbox.io](https://codesandbox.io/embed/762pz5) |
| [Mines →](https://gambatracker.com/verify/gamdom/mines) | server seed, client seed, nonce + hashed server seed, mines | casino's own code | [codesandbox.io](https://codesandbox.io/embed/qqp4c8) |
| [Keno →](https://gambatracker.com/verify/gamdom/keno) | server seed, client seed, nonce + hashed server seed | casino's own code | [codesandbox.io](https://codesandbox.io/embed/xv6v5s) |
| [Pocket Dice →](https://gambatracker.com/verify/gamdom/pocket-dice) | server seed, client seed, nonce + hashed server seed, risk rolls to list | casino's own code | [codesandbox.io](https://codesandbox.io/embed/kzgkrs) |

The casino shows you the hash of a secret server seed before you bet; you add your own client seed and a nonce that counts your bets. Once you rotate the pair, the server seed is revealed and every bet on it can be recomputed.

## Hash chain · 3 games, from a round hash from a pre-committed chain

Hash chain

| Game | Inputs | Vectors | Algorithm source |
| --- | --- | --- | --- |
| [Crash →](https://gambatracker.com/verify/gamdom/crash) | game hash + salt, previous rounds to list | casino's own code | [codesandbox.io](https://codesandbox.io/embed/crash-verifier-4nl2fc) |
| [Roulette →](https://gambatracker.com/verify/gamdom/roulette) | game hash + salt, previous rounds to list | casino's own code | [codesandbox.io](https://codesandbox.io/embed/roulette-verifier-h7kk65) |
| [Hilo →](https://gambatracker.com/verify/gamdom/hilo) | game hash + salt, previous rounds to list | casino's own code | [codesandbox.io](https://codesandbox.io/embed/hilo-verifier-p79lsk) |

Every round comes from one long chain of hashes made before launch. The casino publishes the last link in advance; hashing a round backwards reaches it, and a salt chosen after the commitment (a Bitcoin or Ethereum block hash) turns each link into a result.

**A fair result is still a result with a house edge.** Passing a check here proves the casino did not change the outcome after the bet was placed. It does not mean the odds favour the player, and no check improves them. Gambling can be harmful.
