Reversi (also known as Othello) is a pretty simple game. It consists of a 8x8 square board, and pieces with one black and one white side. Each player has a color, and the aim of the game is to get more of your pieces on the board than the opponent's pieces.
Gameplay
At the start of the game there are four pieces on the board, two white and two black. You must try to capture opponent pieces and flip them over so they turn into your color. You do this by making a horizontal, vertical or diagonal line of pieces, where your pieces surround the other player's pieces. The surrounded opponent pieces are then captured and will be flipped over to your color, increasing the number of your pieces on the board.
Example: You have the black pieces. There is one black piece on the board, next to it are 4 white pieces in a line. You put a black piece at the end of the line, now you have 4 white pieces between 2 black pieces, so those white pieces turn to black.
Every move you make must capture some opponent pieces. This means that every time it's your turn you must place one of your pieces next to a line of one or more opponent pieces, where there's another one of your pieces at the other end of the line. It sounds complicated, but we show you the available squares for moves with semi-transparent circles, so it's easy to learn the game once you start playing.
If there is no available move on the board that captures pieces then you must say Pass and your opponent gets to play again. If both players say pass in a row then there are no more moves on the board and the game ends. Usually it ends when the board is completely full though.
