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.
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 scheduled for January 19th 2018.

Due to the scheduling of the final of the first round of the Netherlands National Olympiad in Informatics we have moved the CodeCup final 2018 to Friday 19 January 2018, 12:00 GMT. We have also scheduled the remaining test competitions. There will be no more changes in the number of Swiss rounds and in the number of players that will be selected in the final round.
Today, 27 July, we have published the new CodeCup game 2018 . It is called Blackhole. The rules and the game are kept easy. Nevertheless we think we have an intriguing game for you. Because of this the Dutch students of the Dutch Olympiad in Informatics (NIO) can also participate in this contest instead of the website nio3.codecup.nl. We hope you like the new game. At the moment there are not yet Caia tarballs for Windows due to technical problems. We are working on a solution. We are sorry for this. The submissions section in open.
