2015 May 5k (Spring Semester)

A tiny code game/app competition!

Changes from past competitions: Different prize payouts, and players can now work in teams of two.

Welcome to the KTBYTE 5k Contest for U.S. Middle + High School Students! This regularly occuring contest aims to support pre-college computer science education. Furthermore, this competition aims to promote creativity and design.

5k competitions use Processing.js and Processing Java. Your application must work in both, and the application must max 5kb of code. Click on the pictures above to see past entrants.


Due to popular demand, we are splitting the prize pool among more contestants. This will reduce the first and second prizes substantially, but it will give many more people a chance to win.

Judges will consider four measures when ranking projects:

  1. The popularity of the submission according to votes (voting will begin after the submission deadline)
  2. The technical complexity of the submission
  3. The subjective appeal of the submission (including performance in the browser / other devices)
  4. The uniqueness of the submission
