Contestants last year



Thinking out of the box

The goal of this challenge is to introduce the youth to interesting problems that can’t be solved by math or computer science concepts mechanically taught at schools.

Contestants need to utilise their very own creative approach and should be passionate about these unconventional kind of problems. Last year, one successful solver picked at random received a packet of full of new Hack Kosice swag. This year, you can get a Wild card for HK23! Do you have what it takes?
