CodeCup 2019 - An online programming competition

Welcome to CodeCup!

We offer you a challenging programming contest. Anybody can participate; there are no age restrictions or other special requirements. The CodeCup never charges entry fees.

In 2019 the game for the contest is Flippo. We have placed a description of the rules online. You can always watch a sample game being played.


After you login in to the CodeCup system you can submit your program. You can find the submission section under "My submissions". Your submission will be tested automatically against our sample players to ensure that it follows the rules. After passing this check your program is ready to compete! Note that your program must be capable of playing both as white and black.

We will hold test competitions every three weeks starting at the end of September. In these competitions you will see how your program performs against other players. You can follow the complete games and use this information to improve your strategy.

The official Flippo competition has been played on January 19th 2019. You can go directly to the final ranking of the programs.

The CodeCup contest 2019 was won by Tomek Czajka. He has won the CodeCup now for the fifth time, earlier in 2006, 2008, 2009 and in 2012. The organizers congratulate Tomek with this victory. Tomek made clear with the last version of his program that his player had very special qualities. You can read more about this in the discussion in the forum. He won with this player several games with the ultimate score of 60-0. Two of these matches ended in a completely black board in favor of Tomek. We hope you liked this years contest. We have the CodeCup game 2020 ready and we hope to publish the game much earlier then August 2019.
