Clock is a solitary game, requiring just one player and a standard deck of fifty-two cards. The objective of Clock is to get all of your cards in their appropriate time slot before capturing all four kings. Shuffle and deal out thirteen stacks of four cards. Starting with the top of your playing field, put one card face down at the twelve o'clock position. Follow that by placing one card face down at the one o'clock position and so on, until you reach the eleven o'clock position. Place a thirteenth card in the center of the circle to form the “hand” of the clock. Repeat this three more times until the deck is entirely used.

Turn up the top card in the clock hand. Move this card to its corresponding time slot (one through ten are, respectively, one through ten o'clock, jacks are eleven o'clock, queens are twelve o'clock, and kings form the clock hand). Place the card face up at the bottom of the pile of its time slot, and take the top card from the same time slot. For instance, you would place a four face up on the bottom of the four o'clock time slot, take the top card from the four o'clock time slot, and move that to its time slot. Move this card to its corresponding time slot and continue play. If a king is turned over, this goes at the bottom of the clock hand, and the top card of the clock hand is played. The game ends when all of the kings are face up and there are no more cards to be taken from the clock hand or when all of the clock times are face up. If the kings are turned up first, you lose. If the clock is turned up first, you win!
