4-Player Othello

Go for 1st place or just avoid last — your strategy is your own. Unexpected comebacks await in the final turns — the winner isn’t decided until the very end. ■ Rules ① The basic rules are just like traditional Othello: players take turns placing stones and flip the opponent’s stones when sandwiching them. ② When the board is full, rankings from 1st to 4th are determined by who has the most stones. ③ If you can't make a valid move, you can place a stone on any empty space adjacent to an opponent’s piece. ■ Online Play ・Battle real-time with players around the world! ・Share a room code to easily play with friends. ・If fewer than four players join, CPU players will automatically fill in. Fully free to play — no hidden fees!
