About

Reversi is a two-player strategy game invented in the 1880s. Players take turns placing discs on an 8x8 grid, capturing straight lines of enemy discs by flanking them at both ends. If a player has no legal move the turn passes. When the board fills up or nobody can move, the colour with more discs wins.

Tips

  • Corners can never be flipped, so take them and avoid the squares right beside an empty corner.
  • Having more legal moves than your opponent is worth more than having more discs early on.
  • Build stable edges anchored on a corner; they become a safe base for the endgame.
