A loop inside a loop: the inner loop goes along one side, the outer loop does it again.

Got it? Now solve your puzzle ↓ (a different board — work it out yourself!)

💡 Need a hint?

One side is “repeat 4 [forward]” and a turn right. Now repeat that whole side — a loop inside a loop!

What you learn here

A loop inside a loop is called a nested loop. The inner loop runs completely every time the outer loop goes round.

Chapter 2 — Loops: When the same steps come again and again, put them inside a repeat block — and even a loop inside a loop.
