How do you know the deck isn't stacked? Jackson.io uses Provably Fair algorithms.

​The Seed: A combination of a Server Seed and a Client Seed (yours!) creates a unique hash.

​The Reveal: After a hand, you can verify the SHA-256 hash to ensure the shuffle was truly random.

​Transparency: In Cardz, the deck is transparently shuffled before the first card even hits the digital felt.
