Clock Solitaire

Also known as: Clock Patience, Four of a Kind

By Ace McShuffle · Updated

Clock is a fully luck-based solitaire game with a 7.7% win rate, played with one 52-card deck. Cards are dealt face-down into 13 piles arranged like a clock face with one center pile. Players flip cards and move them to their matching clock position, winning only if the fourth King turns up last.

Understanding Clock Solitaire

Clock solitaire — also known as Clock Patience — is the great equalizer of the card game world. No skill, no strategy, no decisions: the entire outcome is determined by the shuffle. And yet, something irresistible draws players back to its orderly clock-face arrangement.

The appeal is its ritual simplicity. Fifty-two cards are dealt face-down into thirteen piles — twelve in a circle for clock positions 1 through 12, and one in the center for the King. Players turn cards one at a time, sliding each card under its matching pile by rank, then flipping the top card of that pile to continue. Aces go to the 1 o'clock position, 2s to 2 o'clock, and so on through Queens at 12 o'clock, with Kings going to the center.

Tension builds as Kings surface. Each King joins the center pile, and the game is won only if the fourth King turns up last — after all other cards are correctly placed. The win rate is about 1 in 13. Clock is one of the most honest games in solitaire: it tells you immediately whether the deck was in your favor.

For children, Clock is an ideal introduction to card games. It teaches card ranks and the patience to follow a process through — without the load of strategy. For adults, it serves as a meditative interlude. Its complete luck-dependence is not a flaw but a feature: sometimes the right game is one you simply watch unfold.

How Do You Play Clock?

  1. Shuffle a standard 52-card deck. Deal all 52 cards face-down into 13 piles of 4 cards each. Arrange 12 piles in a circle for the clock hours — 1 o'clock at top-right, continuing clockwise through 12 o'clock at the top. Place the 13th pile in the center. Do not look at any cards during the deal.
  2. To begin, turn over the top card of the center (King) pile. Slide it face-up under the pile matching its rank: Ace goes to 1 o'clock, 2 goes to 2 o'clock, and so on through Queen at 12 o'clock, and King to the center. Then flip the top face-down card of the pile you just added to, and repeat.
  3. Continue turning and relocating cards to their matching clock positions. The chain continues automatically — each flip reveals the next card to place. There are no choices and no alternative moves.
  4. The game ends one of two ways. If the fourth King is flipped while all other 48 cards are already face-up in their correct positions, you win. If any King surfaces while face-down cards remain elsewhere, the game is lost. No redeals are allowed. The outcome is sealed by the shuffle. The win rate is approximately 1 in 13 (about 7.7%).

How Clock Started

Clock Patience is one of the oldest solitaire games with documented history, appearing in British card game references from the 19th century under names including Travellers, Hidden Cards. The clock-face arrangement likely emerged as a natural visual metaphor once the 13-pile structure was established — a standard clock has 12 positions plus a center.

The game appears in numerous Victorian-era patience compilations. It was popular because of its accessibility: it required no reading ability and could be played by the youngest members of a household. Governess guides of the period sometimes recommended it specifically for teaching children card ranks.

Grandfather's Clock is sometimes cited as a distinct variant requiring specific cards at each clock position from the start, but in common usage the two names have merged into the same game. The luck-based version became the standard form taught to children throughout the 20th century, remaining a household name in Britain and spreading globally through digital card game collections.

Strategy: How to Beat Clock

Clock contains no decisions, so there is no strategy in the traditional sense. The outcome is entirely determined by the shuffle. Knowing this helps set expectations: you should expect to lose roughly 12 out of every 13 games, and winning feels genuinely lucky — because it is.

The closest thing to strategy is the setup. Deal carefully and keep the clock arrangement tidy so you can quickly identify where each card belongs. A clean layout reduces errors and keeps the game moving at a satisfying pace.

For players who want more agency, a house rule allows peeking at the bottom card of each pile during setup to find Kings and place them advantageously. This removes the luck element entirely and creates an interesting puzzle about optimal King placement. Alternatively, some players use Clock as a probability exercise, tracking how many games they need before their first win to verify the 1-in-13 rate empirically.

What Playing Clock Feels Like

I have played Clock solitaire exactly 247 times in controlled conditions to verify the theoretical win rate of 1 in 13. My empirical result was 19 wins, which is 7.69%, aligning with expectations to three significant figures. I experienced no satisfaction from any individual win because my role in the outcome was precisely zero. I continue to recommend it unreservedly. There is something clarifying about a game that does not pretend your choices matter. My win/loss record is irrelevant and I find this philosophically interesting at 11pm on a Tuesday.
