How to play Reversi

Rules used here

Standard Reversi · 8 × 8. Bracket opposing discs to flip them. A player with no legal move passes automatically. When neither player can move, the higher disc count wins.

Read a position

A move must enclose at least one opposing disc between the new disc and one you already own. Check every direction because one placement can flip several lines.

A detail to notice

Corners cannot be flipped. A square beside an empty corner can give the opponent access to it, so compare future legal moves rather than choosing only the largest immediate flip.
