About this activity
Create a small program by joining colourful action blocks. Make Momo move, turn, jump, speak or play a note. Add waits and repeat blocks to explore how a sequence and a loop work.
How to play
Tap a block to add it or drag it into your program. Edit its values, reorder blocks with the arrows and press Run. Use Add inside to put actions in a repeat block. Load an example to try one of three challenges.
A little tip
Start with a few actions, then add a loop. Your program stays on the page while you play; reloading starts a fresh playground. The blocks animate this scene and do not execute server commands.
