Duel a playerOpen a duel on your side and your stake waits in the lobby. Whoever takes it puts up the same amount; one flip decides it and the winner takes the pot, less 4%. Cancel any time before it's taken.
Or flip the houseNo one around? Flip against the house: call it right and you get 1.92x your bet, straight away. Both ways return 96%.
Provably fairThe flip comes from the joining player's committed seed (yours, against the house). Check any past flip in Settings › Game History.
