We have 8 people in our household, and there is something for everyone! And when one person is done with one puzzle, we pass it to the next person. Catches our kids attententions for hours, sometimes days. Love how they put different levels of difficulty into each box. We are still working on a level 6. It's kinda like the ultimate conquest in this house. Whoever can figure it out, will get endless bragging rights! Thanks guys keep up the awesome boxes!
