The Clock is a very easy game of solitaire played with 52 cards. You have 13 foundations to drop cards.

Each foundation has a specific card value (the clock value).

You build 4 layers of cards on each foundation that must alternate in color (you can either start with black or red).

Draw card by card from the stock by touching the red back of the card. If the card fits on any of the 13 foundations drag it to the correct place.

Foundations are built by alternating color and layer wise by suit. This means that you can choose your starting suit, but the second card on the foundation must be the opposite color.

Layer wise by suit means that you must have the same suit on each layer of the foundations.

So on all foundations you must have - for example - Spades, Diamonds, Clubs, Hearts in the same order, though you can choose the order during the first moves of the game.

The game allows you to recycle the waste stack exactly two times.
