This was a gift for my grand son. He really likes Lego. What I never realized, was although it says 6+, it’s also fun for adults. It’s 100 times better than jigsaw puzzles. Of course, it encourages learning and has huge play value for kids. As a bit of advice , find a spot to lay out all the pieces. Keep the box and instructions or use labeled ziplock bags and they can be used again and again.
