How to play
The goal
Reversi (Othello) is a two-player game on an 8×8 board played with double-sided discs. The aim is to finish with more discs of your colour than your opponent.
How to play
On your turn you place one disc so that it flanks — traps in a straight line — one or more of the opponent's discs between your new disc and another of your colour. Every trapped disc flips to your colour. You may only move where at least one disc flips; if you can't, your turn is skipped.
Winning the game
Play continues until neither player can move, usually when the board is full. Whoever has more discs wins. Corners are powerful because they can never be flipped — controlling them is the key to strong play.
