Each player in turn may opt to keep his current card or exchange it with the player to his left. If someone tries to take your card and you have a King, you may stop him from doing so by revealing your King. The last player may keep his card or exchange it for the top one from the deck. When you run out of chips, you're out of the game. The last person remaining gets the pot.
Aces are low.
Instead of 3 chips which are lost one at a time, losers pay a higher amount and are knocked out immediately. This yields a faster game. To cancel this advantage, when only two players are left the second player can't look at his card until after the first player has chosen to exchange or hold. Top card of the deck is flipped over, and the suit of the flipped card becomes the trump suit for the hand. Players secretly put a chip in their fist if they want to stay in, or form an empty fist if they don't.
