Play Othello against the computer

You can play Othello, also called Reversi, against the computer on DiceyTable. It is free and runs in your browser. Open Reversi / Othello, pick the Scripted version, add a bot to the empty seat and choose a difficulty.

There are two kinds of opponent. The Othello AI is a neural network trained by playing against itself, and it comes in three levels. The Minimax bot looks ahead through possible moves and has Easy, Normal and Hard. In the Scripted version, the game's script enforces the rules, shows whose turn it is and declares the winner.

The bot runs in the host's browser, which is yours when you play alone. When the game ends, Return to lobby sets up a rematch, and a game against a bot can count toward your ranked Score.
