Three Musketeers is an abstract strategy board game by Haar Hoolim. It was published in Sid Sackson's A Gamut of Games. The game is notable in that, like the traditional Fox and geese, it uses the principal of unequal forces; the two players neither use the same types of pieces nor the same rules, and their victory conditions are different.


Rules
Three Musketeers is played on a five-by-five square board with an initial setup as follows; number signs represent the Three Musketeers and zeroes represent the Enemy:

0000#
00000
00#00
00000
#0000
The players take turns moving one piece; the Three Musketeers player starts. The rules are as follows:

The Three Musketeers player can move a Musketeer to any orthogonally (non-diagonal) adjacent space occupied by an Enemy; the Enemy piece is removed from the game. 
The Enemy can move one Enemy piece to any orthogonally adjacent empty space. 
The Enemy wins if it can force the Three Musketeers to be all on the same row or column.

The Musketeers win if on their turn they cannot move due to there being no Enemy pieces adjacent to any Musketeer and they are not all on the same row or column. As long as one Musketeer can move, the game is not won.
