The Internet Problem Solving Contest is an online programming competition for teams of up to three people. Each year, hundreds of teams gather to solve challenging problems and test their skills against some of the best programmers in the world.
The problems range from easy to very hard, so everyone is welcome to compete. We also have separate ranklists for individuals and secondary school students. You can use any programming language, or even solve problems by hand. Most of the problems are algorithmic in nature, but IPSC is particularly known for its unusual and fun problems. Here are some of our favorites:
If that sounds interesting, you should compete in the next IPSC! Until then, you can also try solving the above problems in the Training Area. Or browse through our Archive and see if anything else catches your eye.
Congratulations to the winners, and thanks to everyone who participated! We hope you had fun, and we're looking forward to seeing you again next year.

We still don't have enough postcards from all over the world. Therefore the annual special task remains: You are encouraged to send us a nice postcard. If the postcard arrives before IPSC 2015 begins, your team will be awarded -60 penalty minutes. (Don't forget to write the name of your team on the back of the postcard.)
