Clock Patience Solitaire is a solo card game played with a standard 52-card deck. Arrange the cards into 13 piles of four cards each, resembling the numbers on a clock with an extra pile in the center. The goal is to turn all piles into sets of four-of-a-kind before revealing the fourth king. Start by turning the top card of the center pile face up and place it under its corresponding pile number. Continue revealing and placing cards until all piles are complete or the fourth king appears, which ends the game. This game is primarily luck-based, with winning occurring only about 1% of the time.
