Baker's Dozen Solitaire is a single deck solitaire card game. The 52 cards are dealt into 13 piles of 4 cards. The bottom card on each of these piles is dealt face down. Before play starts, all Kings that are dealt face up are moved to the bottom of each pile. The top card in each pile may be moved to build down the piles regardless of suit, or build up the foundations by suit from Ace to King. When all the cards in a pile have been removed, that pile can no longer be used. The player wins by moving all the cards to the foundatinos.
