Reversi Puzzles
Reversi is a classic two-player game. Black moves first; White responds.
When you place a disc, it captures every opponent's disc that ends up sandwiched between your new disc and another of your own (in any row, column or diagonal). Captured discs flip to your colour.
Every move must capture at least one opponent disc. If you have no legal move, you pass automatically. If neither side can move, the game ends.
The player with more discs at the end wins. Equal counts means a draw.
Levels: 6×6 (faster, ideal for learning) · 8×8 (classic Othello).
The black disc closes the top row against another black disc and, at the same time, closes a column against the black disc below: all four sandwiched white discs flip.
In each puzzle, the player to move can win. Find out how: the computer will defend as well as it can.
