The Rules of Baker's Dozen

You have 13 piles of 4 cards each, in which Kings are, if necessary, moved to 
the last position. The goal is to put all cards on the foundation, in order 
Ace to King.  You are allowed to move all cards from the top of the piles 
(and from the top of the foundations) onto a pile where the last card is one 
more than the moved one, or onto the foundations (so a 5 of hearts could go 
under any six, or above the 4 of hearts in the foundation). Holes cannot be 
filled (this is why Kings are put on bottom of the piles, as they can be 
moved only onto the foundations). I like it, because it's rather quick, has a 
decent probability of success, and it's not automatic.

Baker's Dozen may be customized by changing the number of slots (in the range 
2..13). With fewer slots, the cards of lower rank are already moved to the 
stack, which makes the game easier.
