A very simple solitaire game for one player, which is played with a Double-Six domino set (28 Dominos).
Play:
The dominoes are shuffled, facedown, and then 7 stacks-of-three facedown tiles are set in a row. Then each of the remaining 7 tiles are placed face-up on each one of the 7 stacks-of-three.
The player now removes any pair of top face-up tiles that total 12, and turns the two tiles below them face-up. Play continues until no more pairs can be removed, with the object of the game being to remove all the dominoes from the layout.
Once the bottom tile of one of the 7 stacks is removed, it is left empty and a player may not fill it with another domino from the rest of the layout.
Variations:
A larger domino set can support a greater number of players or extend gameplay.
With Double-Nines (55 Dominos) 11 stacks-of-5 Dominos, pairs should total 18;
With a Double-Twelve set (91 Dominos) 13 stacks-of-7 Dominos, pairs should total 24;
With a Double-Fifteen set (136 Dominos) 17 stacks-of-8 Dominos, pairs should total 30;
With a Double-Eighteen set
(190 Dominos) 19 stacks-of-10 Dominos, pairs should total 36.
When played as a
solitaire game, the player counts how many turns he takes to remove all the
tiles from the layout, and it is this total which becomes his score and the
player simply aims for their lowest personal best.
