Know what you are playing
ProvablyHero is an independent project that helps you understand casino game probabilities, model possible sessions and replay supported provably fair results. Start with a game, choose an action and inspect the numbers before risking money.
- Calculate: inspect slot probabilities, captured payout tables, theoretical return and expected loss.
- Simulate: explore possible fixed-stake sessions using a seeded statistical model. Simulation results are estimates, not predictions.
- Verify: replay a disclosed bet with its server seed, client seed and nonce. Each adapter identifies its supported algorithm and evidence status.
Current coverage
The working game tools currently cover Plinko. Supported operator tables and verifiers are listed on Tools and Verify. Other games marked Coming soon are not working tools yet. The navigation groups tools, comparisons and guides by game so coverage can expand without changing how you find them.
Who maintains the project
ProvablyHero is maintained by an independent site owner. Articles with a byline link to their author profile and publications. We do not claim a professional accreditation, casino audit or certification. Judge each calculation by its inputs, sources and reproducible method.
What a result does and does not prove
A matched replay checks a particular result-generation algorithm within the scope described by the verifier. It does not establish that a casino is safe, licensed for your country, solvent or willing to pay withdrawals. A mathematically reproducible game can still have a house edge. Tools do not predict unrevealed outcomes or guarantee profits.
How the site is funded
Some operator links are affiliate links. We may earn a commission when you register or otherwise qualify under an affiliate agreement. Commissions do not change the formulas, captured tables or evidence labels. We do not publish an overall casino safety ranking. Read the affiliate disclosure.
Open calculation engine
The calculation engine is public under the MIT license. Its repository includes supported adapters, tests and evidence notes. Operator tables are maintained as versioned project data; a table capture is not a guarantee that an operator still uses that table. Read the methodology for the current scope.
