The goal of the game is to get rid of your cards before the other player(s).
Three cards are dealt face down to each player. Players are not allowed to look at these cards. Then six cards are dealt to each player. Players look at these cards in their hand then select three cards from their hand and place them face up on the three face down cards in front of them. Typically, better cards are placed face up.
The remaining cards are placed face down to form the draw pile. The top card of the draw pile is turned over to form the discard pile.
The first player plays a card that is equal to or of higher value than the previous card by placing that card on top of the discard pile. You can play multiple cards in your turn, as long as they're all equal to or higher and of the same rank.
Once you have finished your turn, draw cards from the Draw pile to maintain three cards in your hand at all times.
Play continues around the table until the draw pile is depleted.
Keep playing until there are no cards left in your hand. If you can't play on your turn, you still have to pick up the discard pile and put it in your hand.
When it's your turn and you don't have a hand, pick up the face up cards in front of you, and add them to your hand.
When it's your turn and you've played all your face-up cards, pick a card that's face-down on the table. Don't look at it to choose. Simply flip it over. If it plays on the current card by being equal or higher, you can play it. If not, you must pick up the discard pile. If you pick up the discard pile, you must play those before continuing to play your face-down cards.
