One of my better games: Odd

I invented this a few years ago, on a lark, without playtesting or more than a few seconds consideration. But it turned out to be one of the best ones I’ve designed, out of hundreds. I wish all games were this easy. Bonus points for being the simplest of all my games.

Odd is a game for two players, played with black and white stones on this initially-empty board:

Definition: A Group is a set of connected, like-colored stones on the board, containing at least 5 stones


  1. Players take turns. On your turn you must place either one black stone or one white stone onto any empty space.
  2. The game ends when the board is full. Player 1 wins if there is an odd number of groups on the board (counting both black and white groups); Player 2 wins otherwise. Example:


In the picture above, there are 3 groups (one white and two black), and because there’s an odd number, player 1 wins.

Note: The game can be played on larger boards and in that case you should change the minimum number of stones in a group. A good rule of thumb is that the minimum group size should equal the number of cells on one side of the Hex board.

  1. Never mind my last. I noticed that your broken link referenced BGG, and found the page (and links) there. I look forward to trying it tonight!
