Three cards each are dealt to ten tableau piles. One card each is dealt to three center piles. The rest are in a deck.
Select two cards that are equal to 17. Jacks, queens and kings are worth 11, 12 and 13. So jack+6 is a valid pair. These pairs will be discarded.
In addition to pairs that equal 17, you can also choose Ace+2+3. Do this by choosing two of the cards. If the third is available, it will automatically be added to the set and all three will be discarded.
When you empty one of the three center piles, it will immediately be filled with a new card from the deck until there are no more cards left in the deck.
The goal is to remove all of the cards.
By default, you cannot see the two cards under the top card of each tableau pile. But a rule preference allows you to see those cards, making the game easier to win.
