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 2023 the game for the contest is Entropy. 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 chaos and order.
We will hold test competitions every three weeks starting Augustus 20th. 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 Entropy competition has been played on January 21st 2023. You can go directly to the final ranking of the programs.

January 21st saw the final round of this year's CodeCup competition of the game Entropy. This year, again, Tapani Utriainen won the competition with a significant distance to the number 2. We noticed that among our participants we had a top-10 of contributions that competed for the best possible Entropy player ever. We will probably never know how strong Tapani's player is compared to that of, say, 5-time world champion on his first CodeCup win.
