About this Game
Play Othello online free — no download, no signup needed. Reversi (Othello) is the classic disc-flipping strategy game on an 8×8 board. One move can swing the entire game — that's why they say 'a minute to learn, a lifetime to master.'
Stone Online lets you take on real opponents around the world in real time. Master corner control and edge tactics against players who fight back. Completely free, instant play in your browser.
The modern version was trademarked in 1971 by Japan's Goro Hasegawa, named after Shakespeare's play. Tens of millions play worldwide, with the World Othello Federation hosting international championships.
How to Play
Start with two black and two white discs placed diagonally in the center. Black goes first. Place a disc to sandwich opponent discs horizontally, vertically, or diagonally — they all flip to your color.
Every move must flip at least one disc. No valid move? Pass. The game ends when the board is full or neither player can move. Most discs wins. The key strategy: grab corners — they can't be flipped back. Play a real opponent and you'll see why!
