Use one pack of cards.
Shuffle and deal out all of the cards facing down to create thirteen stacks with four cards each. Twelve of the stacks should be in the same position as the numbers on a clock and the thirteenth stack should be in the middle.
Turn over the top card in the middle stack.
To complete all the numbers around the clock face before exposing the last king.
Faced up cards are moved to the stack with a clock number corresponding to the card value. Kings are moved to the central stack.
When a card is moved to a stack, it is placed at the bottom of it and the top card in that stack is turned over.
Once a stack consists of four faced up cards corresponding to the clock face, it is no longer in play.
When the last King has been exposed, the game has finished.
Consider getting rid of particular card suits early.
