In Clock Patience game cards are laid out to represent the face of a clock.
Twelve piles of four cards each are laid out, face down, forming a circle.
The remaining four cards are placed, face down, in a pile in the centre of the circle.
The twelve positions around the circle represent the 12 hour clock and the pile in the middle represent the hands.
Play starts by turning 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.
The game is won when all cards are revealed. The game is lost if all four Kings are revealed and face-down cards are still present.
