CodeCup 2018 - 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 2018 the game for the contest is Blackhole. 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 red and blue.

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 Blackhole competition has been played on January 19th 2018.You can go directly to the final ranking of the programs.

On Friday 19 January the final competition of the CodeCup 2018 was held. The winner of 2013 and 2016, Abdessamad Elkasimi, has won the CodeCup for the third time. Congratulations to Abdessamad. This year we had a record number of 109 participants. This number includes 41 participants from the NIO (Dutch Olympiad in Informatics) consisting of 40 Dutch students and 1 teacher. Reijer van Harten won the Windesheim Digitalis price. In December we have worked on the new game for 2019. We think we have a nice game for you. Again, next year we will have the CodeCup and NIO contestants mixed. We will perform some maintenance on the CodeCup system and hope to go live shortly after.
