Reversi Solver
Set up any Reversi position on the board below and the engine will rank every legal move, highlight the strongest one, and show you the alternatives. Use it to check your ideas, study openings, or find the best move in a real game.
Tap a highlighted square to play that move — the engine re-analyzes the new position automatically.
How the Reversi solver works
The solver runs the same minimax search with alpha-beta pruning that powers the Expert computer opponent. For the side to move, it tries every legal move, looks several moves ahead, and scores the resulting positions using corners, stability, mobility and disc count.
Reversi rewards deferred advantage, so the best move is rarely the one that flips the most discs. Treat the recommendation as a strong study guide rather than a proof of perfect play, and compare it with your own reading of the position.
