About Reversi (Othello)

Reversi, also known as Othello, is a strategic board game played on an 8×8 grid. Place discs to flip your opponent's pieces — any opponent discs sandwiched between your new disc and an existing one flip to your color. The player with the most discs at the end wins.

How to Play

  • Click a valid cell to place your disc
  • All opponent discs between your new disc and another of your discs flip to your color
  • You must make a move that captures at least one opponent disc
  • The player with the most discs when the board is full wins

Tips for High Scores

  • Corners are the most valuable positions — they cannot be flipped
  • Avoid placing near corners early — it gives your opponent access to corners
  • Focus on stability, not just quantity of discs

FAQ

What happens if I have no valid moves?
Your turn is skipped and the opponent plays again until you have a valid move.
What is the maximum number of discs?
There are 64 cells total, so the maximum for one player is 64 minus any remaining opponent discs.
