Players take turns placing their colored disks on the board, aiming to trap and flip their opponent's pieces. Every time you bracket one or more of your rival's disks in a straight line (horizontally, vertically, or diagonally), those disks flip to your color. The game continues until the board is full or no player can move.
Success in Reversi relies on predicting your opponent's moves and controlling key positions, like corners and edges. Advanced players balance aggression with defense, carefully timing their flips to maximize final score. Each round is a fresh puzzle, rewarding adaptation and foresight.
This version of Reversi lets you select from several AI difficulty levels, from beginner to expert. Whether you're learning the basics or testing advanced strategies, you can challenge yourself and improve over time. The computer adapts its play style to provide a suitable challenge for everyone.

The goal in Reversi is to have more disks of your color on the board than your opponent by the end of the game. Use your mouse to select a square and place your disk. You can only place a disk if it will flip at least one of the opponent's disks by bracketing them in a straight line. Take turns with the AI, making moves that capture the most territory or control key board positions. When neither player can move, the game ends, and the player with the most disks wins. Corners and edges are valuable positions, so try to plan several moves ahead and anticipate your opponent's strategy.
Control corners - Securing the corners makes your disks harder to flip. Plan ahead - Think several moves forward to avoid giving away strong positions. Limit opponent's options - Try to force the other player into making weak moves. Edge play - Edges are safer than the center, so prioritize them when possible. Balance offense and defense - Aggressive flipping can backfire if not timed well. Watch for forced moves - Avoid situations where you have no choice but to make a bad move.
