Clock Solitaire is a solitaire card game where cards are placed in a clock-like layout. The aim is to uncover all cards before four kings. If four kings are uncovered before all other cards, then the game is lost.
The game starts by dealing 4 cards each to 12 clock positions face-down. Remaining 4 cards are placed face-down at the center of the clock and top card of center pile is turned face-up. This card can then be moved to bottom of the pile at its respective clock position and top card of that pile is turned face-up which can again be played in similar fashion. The game continues in this fashion revealing top card and then moving that card to its clock position.
