What provably fair means.

Use the record for the right mode

For real-money games, open Fairness from the table inside the game to review your seed controls, then use your saved real-money results and the verifier attached to the applicable record. The practice verifier on this website checks practice records only.

Sand Arena has practice and real-money casino records. They use their applicable versioned algorithms and recorded inputs; a result from one mode must not be checked as if it came from the other. Real-money records also bind the draw to their recorded account and game profile. The verifier needs the full record, not only a winning number.

Revealing a server seed starts a fresh hidden seed for future rounds. Finish active Blackjack, Gem Mines and Higher / Lower sessions before revealing a seed, because early disclosure would expose information about unfinished play.

Glider Crash uses a shared commitment

Players share a flight, so Crash uses a chain of seeds committed before that chain’s rounds. A finished flight reveals the seed needed to check the chain link and reproduce its crash point. Use the Crash verification controls for these results, not the personal-seed checker.

This verifies consistency with the published chain. It does not prove how the chain was selected before publication. The current chain has no player seed or external public-randomness input.

What verification does not prove

• It does not make a game profitable or promise a win. The rules, house edge, whole-chip rounding and return caps still apply.
• A matching random result alone does not audit the entire balance ledger, all payout calculations or withdrawal delivery.
• It does not prove that a service never cancelled a round or that every part of its operation is independently certified.
• Player duels are combat between players and are outside these casino random-result checks.
