2. DESCRIPTION: China, one of the world's oldest civilizations, consists of states and cultures dating back more than six millennia. This is an abstract strategy board game, originally played with black and white stones on a go board in China. It is well known now in many Asian countries, such as Japan, Korea and Vietnam. There are several variants and people calls them differently. The World Championship of Renju has occurred every two years since 1989. The game is built up here by using Java and Artificial Intelligence.

3. INSTRUCTIONS: Two players, A and B, may put pieces one at a time on any spot (19X19 intersections) of board. Once placed, pieces are not moved or removed from the board. The winner is the first player to get an unbroken row of five pieces horizontally or vertically or diagonally. The player is allowed to block or interrupt opponents line in the middle and at the end of line. Now you can play as player A and go first against a built-in player B in computer. When Game is over, you may restart it by clicking the Restart button in bottom left. -Wei Liu
