Reversi is a board game that sits between checkers and chess in terms of complexity. It’s played on an 8 by 8 board with discs that are black on one side and white on the other. Moves are made into any unoccupied square, but each move must capture at least one of the opponent’s pieces.
When a disc is placed, any continuous run of your opponent’s pieces between that disc and another of your discs will be captured. Captures can be made horizontally, vertically, or diagonally. Captured pieces flip over, changing from your opponent’s colour to your colour. The winner is the player with the most pieces at the end of the game.
This version of Reversi is rendered in full 3D, and allows you to play against either the computer or a friend. Features include:
Five difficulty levels for the computer opponent, from novice to expert.
Unlimited undo of your moves.
Highlighting of legal moves.
Highlighting of the last piece placed.
Automatic saving of the current game when you quit.
