Clock Patience, also called Clock Solitaire, is a luck-based patience or solitaire card game with the cards laid out to represent the face of a clock. It is also known under alternative names such as Dial, Travelers, Hidden Cards, and Four of a Kind.
Clock Patience is a purely mechanical process with no room for skill, and the chances of winning are exactly 1 in 13.
One deck of cards (minus jokers) is used. The deck is shuffled and twelve piles of four cards each are laid out, face down, in a circle. The remaining four cards are placed, also face down, in a pile in the center of the circle.
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 çard of the pile of that hour is turned over. If a King is revealed, under the middle, which is the opposite of the pile for .
Play continues in this fashion and the game is won if all the cards (including four Kings) are revealed; turning up the fourth king means you will have completed the clock and won the game. The game is lost if the fourth King is turned up while any cards remain face down.
A variation of Clock Patience commonly called Watch is played like Clock Patience, but players can continue the play when the fourth king appears, by replacing it with a still face-down card. The game ends when that fourth king reappears.
The Clock (sometimes also called "German Clock") is a stock and waste type of solitaire originally called "Die Uhr", and described in a German solitaire book by Rudolf Heinrich from 1976. This gives rules for very different game-play that depends on skill not to miss cards that can be played to the foundations.
