A card is dealt face up. Guess whether the next card will be higher or lower, aces high. A right guess multiplies your winnings and the new card becomes the one to beat; a wrong guess, or a tie, ends the round and the bet is lost. Cash out whenever you like to take your bet times the multiplier.

Don't like the card? Skip it: the deck beside it deals the next card in its place, free and as often as you like, before your first call or between calls. A skip doesn't change your multiplier; the new card's own chances set what the next call pays.

Higher sits above the card and Lower below it: tap one, or that half of the card. Each shows its chance and what it would pay: the rarer the call, the more it pays. A call that can't win, like higher than an ace, is switched off. Every cash-out point returns the same 97% on average, whichever calls you make.

Every card is drawn from your own provably fair seed pair as the round needs it, and never changes afterwards. After the round, or with New seeds, check the cards on the Provably fair page. A round left open is cashed out after ten minutes (the likelier call is made for you if you hadn't made one).
