Turn over the top card of the central pile. When a card is revealed, it is placed face up under the pile at the corresponding hour (i.e. Ace = 1 o'clock, 2 = 2 o'clock, etc. The Jack is 11 o'clock and the Queen is 12 o'clock) and the top card of the pile of that hour is turned over. If a King is revealed, it is placed face up under the central pile.
Play continues in this fashion and the game is won if all the cards are revealed. The game is lost if all four Kings are revealed and face-down cards are still present.
