From a cognition and growth perspective, I played the game with my son and also my daughter as not only a means to have fun, but also since I figured it would be a good learning tool for them. One aspect of learning in this particular game is the effects of compression. When you compress items together, you need to think about how the physics of compression impacts other objects. In some instances, the compression would bear upon a handful of the pegs and the other pegs were not under any pressure at all. This at first was counter intuitive to my children as they initially assumed that applying pressure would cause all of the pegs to be under pressure.
