Can you discover the winning strategy for each board size?
The aim of this online puzzle is to convert all of the White pieces on the game board to Black pieces.
Clicking on a piece with the mouse will change it from White to Black, and vice-versa. It will also reverse the colors of all horizontally and vertically adjacent pieces.
You can select the size of the board - from 3x3 to 8x8.
The Moves counter will turn red to indicate the minimum number of moves necessary to win, for the selected board size. Beyond the minimum number of moves, the Moves counter will turn gray.
