About Orrery Studio
We build casino games end to end: the math, the physics, the client and the server.
Flip Flap answers one question: can a casino game look like real pinball and still have math a regulator can read line by line? Every ball path is simulated before release, every payout is in the book, and the game client only draws what the book says.
We write down every decision with the numbers behind it and the options we rejected. That habit shapes the games: no autoplay until we can confirm it properly, no “jackpot” wording where it does not apply, no art we did not make.
What you can verify today
- Flip Flap math report, plus the 46-row Engine checklist with the evidence for each row.Math
- Review event ids for every outcome class, replayable in the real client.Replays
- Fairness endpoints of the game server: public, no key needed.Docs
- Not yet: a lab certificate for the direct-integration server, and a supplier licence. They will be listed here when they exist.
