Progredi GAME
Movement can be performed in four directions, straight ahead one or two spaces and diagonally left or right. Once a piece moves, there's no turning back!
The capturing is similar to Othello. If, after moving, a stone 'sandwiches' enemy stones - in the horizontal and vertical directions - between itself and another friendly stone, those stones are removed.
Full instructions are included in the application.
(The graphics resemble the game Go, but this is not the same game)
