Obby Maker: Build a Fair Obby

Grades 4-8 · 45 minutes · Computer science, Game design

Students play a three-stage obby and work out the rule behind every jump: 4 blocks across or 2 up, never 5. They build a stage of their own, and the app tells them in a sentence whether it can be finished. At the end, classmates trade seats and play each other's stages.
