FAQ
What is Reversi?

Reversi (also sold as Othello) is a strategy board game where two players place discs on a grid, flipping opponent discs that are sandwiched between their pieces.

What is the best Reversi strategy?

Corners are the most valuable positions — once taken, they cannot be flipped. Avoid placing pieces adjacent to empty corners (X-squares). Prioritize mobility over disc count in the mid-game.

How is Reversi different from Othello?

Othello starts with 4 pieces in the center in a fixed position. Reversi is the original game with slightly different starting rules. Most modern versions follow Othello rules.

About this test

Play Reversi (Othello) against the AI. Outflank your opponent to flip their pieces and control the board.

How It Works

Place your disc to sandwich opponent discs between your pieces. Sandwiched discs flip to your color. The player with the most discs when the board is full wins.

Key Strategy

Corner control is paramount in Reversi. Corners cannot be flipped and provide stable anchors for controlling edges. The mid-game is about maintaining mobility rather than maximizing disc count.

Tips

  • Capture corners whenever possible
  • Avoid X-squares (diagonally adjacent to corners)
  • Maximize your mobility — having more moves is usually better than having more discs
