Reversi

About Reversi

Reversi is a two-player abstract strategy board game played on an 8x8 grid. This browser build brings the classic game to any device: place colored discs on the board to outflank and flip your opponent's pieces, aiming to control the majority of the board by the final move. Play typically pits you against a computer opponent, though many browser versions of this game also support a local two-player mode. A match starts with four discs already placed in the center of the board, and each turn must legally capture at least one opposing disc or be skipped. Because it runs directly in the browser, no download, installation, or account is required — just open the page and start playing on desktop or mobile.

How to play Reversi

1. The game is played on an 8x8 board, which begins with two discs of each color already placed in the center in a diagonal pattern.
2. Players alternate turns, each placing one disc of their own color on an empty square.
3. A move is legal only if it 'outflanks' one or more of the opponent's discs — meaning it traps an unbroken straight line of the opponent's discs between the newly placed disc and another disc of your own color, horizontally, vertically, or diagonally.
4. Every opposing disc caught in that outflanked line is flipped to your color.
5. If a player has no legal move available on their turn, that turn is skipped and play passes back to the opponent.
6. The game ends when neither player has a legal move remaining (usually because the board is full); whoever holds the most discs of their color wins.

Controls

• Desktop: Click an empty square with your mouse to place a disc there. Squares that are not legal moves simply won't respond to a click — only outflanking moves are accepted.
• Mobile / tablet: Tap an empty square on the touchscreen to place a disc. The board is sized to fit the screen, so no dragging, pinching, or multi-touch gestures are needed.

Reversi tips & strategy

• Prioritize corners — a disc placed on a corner can never be flipped, giving you a permanent, stable anchor on the board.
• Avoid playing the squares directly adjacent to an empty corner (often called X-squares and C-squares) early in the game, since doing so often hands your opponent that corner.
• Don't chase the highest disc count early on — holding fewer discs in the opening and midgame can be an advantage, since it limits your opponent's options and keeps your discs safer from capture.
• Focus on mobility: try to maximize the number of legal moves available to you while minimizing the legal moves available to your opponent.
• Secure corners before pushing hard for edges — edge discs next to an open corner can still be vulnerable to capture.
• In the endgame, count remaining moves carefully; forcing your opponent into a position where they must hand you a corner (a parity advantage) is often decisive.
