Players take alternating turns placing a disc on the board. A legal move must enclose one or more opposing discs between the newly placed disc and another disc of the player's color in a horizontal, vertical, or diagonal line; enclosed discs change color.

The game normally continues until neither player can make a legal move or the board is full. The player with more discs at the end wins. Exact menus, difficulty levels, save features, and multiplayer options depend on the unidentified DOS version.

Control of corners is generally valuable because discs placed there cannot be flipped. Avoid giving an opponent an easy corner entry, and consider moves that limit the number of legal replies.

The most discs during the middle of the game do not necessarily indicate a winning position. Evaluate mobility, stable edge positions, and the likely consequences of each move; version-specific advice cannot be confirmed without identifying the release.
