Better moves

Strategy

Reversi rewards timing. The strongest early moves often flip fewer discs, preserve options, and make it difficult for your opponent to reach stable squares.

Practical Strategy

Own cornersCorner discs cannot be flipped, so they often anchor safe edges and late-game control.
Keep mobilityA player with more legal moves can choose better timing and force awkward replies.
Limit frontier discsDiscs beside empty squares are easier to attack. Too many frontier discs can feed your opponent.

Opening Plan

Do not chase the largest flip on the first few turns. Early disc count can be misleading because those discs may become easy targets. Try to play moves that keep the center compact and avoid handing over corner access.

  • Avoid squares diagonally adjacent to an empty corner unless the tactic is clearly safe.
  • Prefer moves that reduce your opponent's legal replies.
  • Study the score after each move, but avoid choosing moves only because they flip the most discs immediately.

Middle Game

The middle game is about controlling access. You want your opponent to run out of comfortable moves while you keep several playable options.

Good moveTakes a corner, protects an edge, or leaves the opponent with fewer legal replies.
Risky movePlays next to an empty corner or flips a large block that becomes exposed.
Strong replyForces the opponent to play into a bad square or give you a stable edge.

Edges and Corners

Edges become powerful after they are anchored by a corner. Before a corner is taken, edge moves can be unstable because they may give the opponent a way to claim that corner later.

Endgame Counting

Late in the game, disc count finally matters. Look for move order that controls the last empty regions and forces your opponent to pass. In tight endings, one forced pass can swing several discs.

Beginner Checklist

  • Before every move, ask whether it gives away a corner.
  • Count legal replies, not just discs flipped.
  • Try to keep your discs away from too many empty neighboring squares.
  • When the board is nearly full, switch from mobility to exact disc counting.
