Igloo puzzle

The original model was designed with my kids in mind, but they found it challenging to assemble because each piece must be carefully placed before the next one can be added. To make it more accessible to them, I paired up pieces from the second and third layers, which has made it much easier for them to complete. For older children, however, the original design remains a great challenge that will put their problem-solving skills to the test.
