Knights
No. of Players
One
Equipment
Knights is played on a 5x5 square grid. A corner of a larger square grid (chessboard) can be used. The board may or may not be checkered, it is irrelevant to the play. Twelve each of black and white counters, here called knights as they have the move of the knight in Orthochess, are required for play.
History
This game is mentioned in Pentagames (p. 79)
Objective
The objective is for the black knights to exchange places with the white knights in the fewest number of moves.
Play
Knights move as they do in Orthochess: Specifically, they may move two cells in any orthogonal line, and then one cell at a right angle to the first half of the move; or one move to any orthogonally adjacent cell, and then two at a right angle to the first half of the move. Knights may jump over other counters of either color during their move, but must always end at a vacant cell.
Strategy
Pentagames (1) mentions that, with practice you should be able to complete the game within fifty moves but it is almost impossible to do it in less than forty-five.
