What stands out: roulette
Roulette is one of Gamdom’s in-house Originals. This review covers what the site publishes about it: the provably fair method and the operator behind it.
Read the maths in our guide to CS2 roulette house edge.
Fairness
For each game Gamdom generated a chain of 10 million SHA-256 hashes, starting from a secret and feeding each output back into SHA-256. The game server plays the chain in reverse. The final hash of the roulette chain is published on the fairness page, which fixes the chain in advance.
To verify, hash a round’s published hash and check that it equals the previous round’s hash. The fairness page links sample code for roulette and the other Originals. As elsewhere, this proves the sequence was fixed before play; it does not change the payout table.
Follow the provably fair verification steps to check a result yourself. Provably fair proves the draw, not the payout.
Payments
The help centre lists eleven cryptocurrencies, bank deposits through payment providers and Gamdom gift cards from $5 to $250. It notes that crypto deposits can move the balance with market prices, that some deposits carry extra fees and that available methods depend on the country of residence.

Pros and cons
Pros
- The final hash of the roulette chain is published, with sample code to verify each game.
- The footer states operator, registration number and licence number in full.
- Crypto, bank and gift-card deposits are documented in a help centre.
Cons
- The licence comes from the island authority of Anjouan, an offshore regime.

- Fairness is a hash chain checked backwards through published hashes, which takes more tooling to follow than a daily-seed method.
