One-Deck game type. 1 deck. 1 redeal.
Move all cards to the tableau.
The tableau is dealt in a circle of twelve piles, similar to the twelve numbers on a clock, with a thirteenth pile placed in the middle. Each pile represents cards of the number in that position on a clock, with Jacks in the 11 o'clock pile and queens in the 12 o'clock pile. Kings go in the middle.
Deal cards from the stock one at a time. Cards can be moved from the waste pile to the appropriate tableau pile as mentioned above. Tableau piles must be built up by alternate colors, and all of the tableau piles must be built up using the same sequence of suits. One redeal is allowed. The game is won if all cards are moved to the tableau.
German Clock is more commonly known as The Clock. It is not to be confused with another game by that same name.
