Fair Play
Last updated November 2, 2026
You should be able to check that every result is honest. Vex0ra is provably fair.
How it works
- Before you bet, we show you the hash of a secret server seed. We can't change the seed afterwards without the hash changing.
- You can set your own client seed. Each bet's outcome is calculated from the server seed, your client seed and a bet counter (nonce) using HMAC-SHA256.
- When you rotate your seed we reveal the old server seed. Open Provably fair in the app to verify any past bet with the built-in verifier, or with your own code.
Return to player and house edge
Each casino game has a fixed theoretical return to player (RTP), set per game rather than the same for every game, and the house keeps the difference over a long time. For example, several of our originals are set to 99% and others, such as Money Plane, to 96%; the figure for a game is published in the app. Short-term results vary a lot and past results don't predict future ones.
Sportsbook
The Sportsbook is a simulation. Fixtures, scores and results are generated by our software and do not come from real matches. Prices include a built-in margin, so the odds are lower than the true chance of an outcome, and the margin can differ between single bets and combinations. Cash-out offers are set by us and can change or be withdrawn at any moment. The provably fair verifier covers casino rounds and does not apply to simulated Sportsbook results.
Vault Arena
Vault Arena games are played for fun and nothing is staked. Where a game involves chance, such as dealing cards, it is handled by the server. Some opponents are computer-controlled bots, which you can choose to play against.
Demo Slots
Demo Slots are third-party games run by freedemo.games and the studios that made them. Their results and RTP are determined by them, not by us, and are not covered by our provably fair system. They use their own demo credits, which do not touch your Play Money balance, stats or leaderboards.
No real-money prizes
All winnings are in Play Money, which has no cash value. See the Terms.
Cheating
We monitor for bots, multi-accounting, collusion and exploits, and may remove Play Money or ban accounts involved. Report concerns via support.
Vex0ra is a virtual play-money entertainment game for 19+. Play Money has no cash value and cannot be redeemed.
