You see your card before choosing a stake from 1 point up to your balance. The computer’s card stays hidden until you reveal it. Higher rank wins; equal ranks use clubs > spades > hearts > diamonds.
Choose a preset, use the slider or enter your stake. Reveal the card, then deal the next round.
Win: add the stake. Lose: subtract the stake. Start with 100 points; finish after your chosen rounds or at zero points. Each of the 52 cards is dealt at most once.
Tab selects controls; Enter or Space activates them. Stakes and all game actions support keyboard, touch and mouse.
Active time starts with your first reveal and pauses in menus, demos and the background. Timer display is off by default. Your round resumes on this device.
For entertainment only. No real-money stakes, purchases or prizes. Points cannot be paid out, traded or exchanged.
