Rules

Two players called Dark (black) and Light (white). Each player puts one piece per turn on the board. The piece must be put on a space so that it sandwiches one or more of the opponent's lines (diagonal or vertical).

The sandwiched disks are flipped to the color of the current player.

If a player can not play, he must pass his turn (a "pass" symbol is displayed).

"Pass" symbol

The game is over when both players can not play. The player with the most pieces wins.

Why this name: Annexation?

It is generally admitted that "Othello" is a trademarked brand used to market this game and that "Reversi" is the game name to be used freely, and it is indeed named "Reversi" in many implementations around the Web. However, Ravensburger came to us, claiming the ownership of the "Reversi" brand and forbade us to name our implementation that way.

We decided to switch to the original name back in the late 19th century: Annexation.
