Batwheels - 1x12 + 1x16 + 1x20 + 1x24 pezzi

The 12-piece puzzle was just right for my 3-year-old to start, and the pieces are thick enough they don't bend easily. Seeing her work up to the 24-piece one over a few days was really satisfying.

My nephew loves that each image is different and the piece counts go up gradually; he started with the 12-piece and is already proud to try the 24. The cardboard pieces are thick enough for little hands and click together satisfyingly.

My 4-year-old has been obsessed with these since they arrived, and I love that the 12-piece puzzle is easy enough for him to start solo before we tackle the 24-piece one together. The images are bright and the cardboard pieces are sturdy, so they've survived being bent and thrown around a few times
