The series of small joys at each step solved reminded me very much of Johnson's "Everything Bad is Good for You". The way video games can reward our brains in small bursts is almost unparalleled. To me this is what a learning game should be like. I try to avoid the term educational as it invokes unpleasant memories of unimaginative drill games. Well it is a learning game...
It teaches to think creatively, look closely, experiment and persist. These are skills that transfer well to any open ended problem that artists and scientists attend to. My play with my boys added another dimension, namely learning to work as a team: we take turns, practice patience, share victories and most importantly never play without the others.
We have since moved to new puzzle games not all of them as visually pleasing but the effects are still the same. They now insist on daily common gameplay and I happily concur. We are creating habits of mind and family bonding. I can only wish that we will find ways to combine this superb game play with content that reaches educational standards.
