I bought this for my youngest nephew. He does get awfully anxious at times, I knew from past experience he reacted positively to puzzles and whenever he would struggle with a situation, we would always sit down and I would 'struggle' to see where the next piece went. It calmed the atmosphere and we would then make progress.
Fast forward a few years on and he still struggles with change. So I spotted this and knew that it would be great. We've made all the different designs and he's made his own too. The funniest part is getting it back in the board.
