This is the computer version of the traditional Chinese board game for two players. There is only one type of winning formation and if both players play perfectly the game will be over in three moves.

Investigations

The artificial intelligence behind this computer version does not always play perfectly so you have a very good chance of winning. You can collect a Transum Trophy if you do manage to beat the computer.

In Korea this game is known as Ou-moul-ko-no and in some English speaking countries it is known as Two Stones.

This game has been analyzed by P. Straffin, [Straffin, P. D. Jr. "Position Graphs for Pong Hau K'i and Mu Torere." Math. Mag. 68, 382-386, 1995.] who showed that it is a draw as long as both players can see two moves ahead, i.e. see the results of their move and of what their opponent would do in response.

"Good afternoon! I am a student of Riga Technical University from Latvia. I want to make the same game as you have in C#, but I can't do it, I can ask you to send the code of this game or some materials that can help me in writing the code. Thank you in advance!

[Hi Daniel, I can't help you with C# programming but if you examine the source code of this page you will see the JavaScript code I wrote. Good luck.]"
