Three Musketeers was first published in Sid Sackson´s A Gamut of Games. Three Musketeers is played on a 5 x 5 square grid board. The bottom left corner, the center and the top right corner are starting spaces for the three musketeers. All other spaces are initially occupied by "enemies." Musketeers can only move to adjacent spaces with an enemy piece, which is captured by this move. Enemies can only move to empty adjacent spaces. Enemies win if all three musketeers are ever on the same line or column. Musketeers win as soon as they run out of legal moves. Musketeers will start the game. According to Wikipedia the game was strongly solved in 2009 by Johannes Laire. The enemies (that could be called Cardinal Richelieu's men) can always force a own win. References are missing but due to the restricted amount of available moves for the Musketeers and the strict, clear, and simple rule set proof is possible with acceptable effort with same result.
