Fifty-two numbers from your seeds shuffle one full deck, fixed when you bet. You get the first card and the dealer the second; in a war three cards are burned and the next two decide it.
We choose our server seed before you bet and show its fingerprint. This commits us to that seed.
Your seeds shuffle a full deck when you bet. Cards dealt from that order decide your round against the dealer.
Rotate your seed to reveal ours. Use both seeds and the bet number to recheck any past result.
