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 2026 the game for the contest is 0.1. 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 red and blue.

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 11th 2025.

News

Much later than planned, we are proud to introduce 0.1, the CodeCup game for 2026. Zero Point One is a two-player strategy game released in 2012, designed and illustrated by Jim Wickson and published by BoardGameGeek.com. We have essentially adapted the original rules. We believe we have introduced with 0.1 a new challenge for you, allowing you to employ different strategies than in the previous decade of the CodeCup. We hope you will like it!
