Domino Pirate Game

"Domino Pirate" is played with a set of dominoes to six. All dominoes are shuffled and placed face down in 7 columns, each column consists of 4 tiles. The last tile in each column is flipped face up. The top tile can be moved from one column to another if either of its two sides matches either of the two sides of the top dominoes in the destination column. Each time a face-up tile is moved from one column to another, the face-down tile just below it (if any) is flipped face-up. An empty column can only be filled with a double. The goal is to move each of the seven doubles to the bottom of each column, and then move 3 more dominoes to the corresponding column's suit of doubles. The game is won when all the chips lie face up in sets of four with one of the seven doubles at the bottom and three more chips of the same suit at the top. The game of domino pirate is over if there are no more moves.
