Every deal, provably fair.
A card-dealing API built to gaming-lab standards. Your game gets a certified-grade shuffle, and every player can check their hand wasn't touched.

How it works
Commit
We shuffle from a secret seed and publish its SHA-256 fingerprint before a single card is dealt.
Deal
Your game calls the API to deal to each seat. The order is fixed by the seed and can't change mid-hand.
Reveal
After the hand we publish the seed. Anyone can replay the shuffle and see it matches the fingerprint.
Built for

Licensed operators
Designed to GLI-19 so your lab review starts from a documented, tested engine.
