How to Play Reversi
Reversi — played under the same rules as Othello — takes only a few minutes to learn. You and your opponent take turns placing discs and flipping each other's pieces; whoever owns the most discs at the end wins. Here is everything you need to start playing.
Reversi is played on an 8×8 board. Start with four discs in the central four squares, placed diagonally so each colour sits on one diagonal: white on D4 and E5, black on E4 and D5.
Black always makes the first move. After that, players alternate turns, placing one disc of their own colour on each turn.
You may place a disc on an empty square only if it outflanks at least one of your opponent's discs — trapping a straight line of their discs (horizontal, vertical or diagonal) between the disc you just placed and another of your own discs.
Every opponent disc caught between your new disc and an existing disc of yours flips to your colour. A single move can flip discs in several directions at once.
Pass when you cannot move
If you have no legal move, you must pass and your opponent plays again. You never pass by choice — only when no move is available. When neither player can move, the game ends.
The game ends when the board is full or no one can move. Count the discs: the player with more discs of their colour wins. An equal count is a draw.
Example: Black's opening move flips a white disc
