Gomoku

Version: 1.0

Gomoku is an abstract strategy board game and is also called five in a row.

Black plays first, and players alternate in placing a stone of their color on an empty intersection. The winner is the first player to get an unbroken row of five stones horizontally, vertically, or diagonally.

Gomoku has a professional variant named Renju (Japanese/Chinese: 連珠), Renju has much more complicated rules for a more fair play in professional matches.

Black can win the game only by placing five black stones in a row (vertically, horizontally or diagonally).

White can win by either:

• getting five (or more) white stones in a row
• forcing Black to make a forbidden move (see below).

The opening sequence differs from ordinary Gomoku:

1. The first player places 2 black stones and 1 white stone on the board.
2. The second player now chooses whether to play black or white.
3. White then places one more stone on the board.
4. Black places 2 stones on the board.
5. White removes one of the two black stones from the previous move.
6. White places a white stone.

After this sequence is complete, Black and White continue to take turns to place their stones.

There are certain moves that Black is not allowed to make:

• Double three – Black cannot place a stone that builds two separate lines with three black stones in unbroken rows (i.e. rows not blocked by white stones).
• Double four – Black cannot place a stone that builds two separate lines with four black stones in a row.
• Overline – six or more black stones in a row.

Renju will be supported in future version that will be distributed via App Store.
