Plinko RTP Audit
A locked result.
An unchecked game.
The hash locks a result. It does not audit the implementation, the odds, the paytable or the house edge.

“We already have provably fair.”
A result can verify perfectly. The game can still be wrong.
A locked result.
One team.
Both sides of the check.
Your team built the game and its verifier. Both can agree—even when the game differs from the rules you advertise.
Verified bets.
Unverified game maths.
A player can check a bet. That does not test the paytable, the edge or how the game behaves across millions of rounds.
Independent proof.
For the whole game.
We rebuild the game from its published rules. Thousands of real bets. Hundreds of millions of rounds. Public evidence.
Players verify against the audited code—so changed games and paytables get caught.
PUBLIC INVESTIGATIONS
The gap isn’t theoretical.
These public investigations show why a fairness claim needs independent, reproducible evidence.

THE VIP QUESTION
If a VIP loses $500k tomorrow and publicly claims your games were manipulated, what do you point to?

HOW CERTIFICATION WORKS
From your games to public proof.
Typically 4–8 weeks
All in-house provably fair games
Scope & independent rebuild
We agree the scope, then rebuild each game from its published rules, independently of your code.
Test the live games
Thousands of real bets must match our rebuild. Simulations and integrity tests check the return, edge cases and timing.
Findings, fixes & certification
You see findings first. Outcome issues must be fixed and re-verified. Findings and resolutions remain on the public record.
ONGOING ASSURANCE
Independent proof.
Ongoing accountability.
Independent checks continue after launch. Every check is public. A failed check suspends or revokes certification.
Ongoing checks. One public record.
Full annual audit
Fresh bets. Every game rebuilt.
Every quarter
Unannounced bets, anonymous accounts
When players verify
Bet links checked against audited code
Full annual audit
Each year, we repeat the complete audit: fresh real-money bets captured through anonymous accounts, a full independent rebuild of every game in scope, and renewed checks of outcomes, payouts, RTP and game integrity. New evidence, findings and results are published in your audit record.
Every quarter
We return as a player, capture fresh real-money bets and re-run them against the audited game code. Results are added to the public record. The review month is published; the exact date and accounts are not announced.
When players verify
Players use a bet link or ID in the verifier. We fetch the bet details, recompute the result against the audited code and add the check to your certificate history. The casino can’t choose which bets get checked or when. A genuine mismatch opens a dispute.
