First you start with Angry Birds, and when you get to level 13 or 14 it changes to Plants v Zombies. Then when you complete it you go to level two. Each level has 20 rounds of Blockly puzzles.
Tip: Sometimes I got frustrated because it was my first time because I said turn right, but it turned left. I didn't understand that my right was different from the Angry Bird's right. But what I did was get my stuffed animal and my mommy asked, which one is my right eye, then she asked which one is my animal's right eye, so then I could see it had to turn left (which was my right).
To brush my teeth, I made my mommy talk to me in code so I got there. It's really true! It was fun!
