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 2025 the game for the contest is Box. We have placed a description of the rules online. You can always watch a sample game being played.

Competition

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 player 1 and player 2.

We will hold test competitions every three weeks starting in 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 next test competition has been scheduled for October 26th 2024.

The CodeCup Team enables you to test your program at home. Our testing software is free and enables you to organize competitions at home without involvement of other people. The software to play at home is called Caia. It works in the same way as our contest software. By hosting your own local competition you can test and improve your program in a fast and easy way.

News

Since a few days we published the new CodeCup game Box. We hope you like it. The final will be held in January 2025, so you will have enough time to program a player for it. The website is now fully operational. This morning a new version of Caia was uploaded because the visualization was missing in the first version. The Dutch high school students have to wait another week for the game Squares that we publish on nio.codecup.nl.
