I used that blockly maze to teach kids at my son's primary school some programming. It starts out simple, and then you progress through loops, conditions, and eventually they have to implement a real wall-following algorithm.
I had 3 students at a time so I could help them a lot, which some kids definitely needed. But some didn't, and came up with some really interesting algorithms.
