Activity Directions


100 Level - No experience necessary

Karel starts at 1st street and 1st avenue. Your job is to build a tower (a stack of 3 tennis balls) on all of the odd avenues in the world. i.e. 1st, 3rd, 5th, 7th, etc.

This must work on any sized world, so there could only be 1 avenue or there could be 100 avenues, and it should still build a tower on every odd avenue.
