What do participants of the congress when they are not programming on their computers? They program robots with cards in the context of a board game (Roboralley), encode words (Decrypto), delve into a dungeon for 5 minutes (5-Minute-Dungeon), or play CPU Quartet. For those who enjoy a challenge, there's also the option to try their hand at punch cards (Turing-Machine). We play games with young people, all of whom have a high nerd factor. The target audience is children and teenagers, starting from the age of eight. The recommended age varies depending on the specific game.
