We bought this game for our then 4.5 year old son. He had started playing chess beforehand but was not consistently moving the pieces correctly. After purchasing the game he quickly picked up the correct moves. He also became quite obsessed with chess and went on to a summer chess camp at 5, joined the school chess' club in kindergarten and just had his first chess tournament (5y3m).
In addition to this game, we also have the computer games "Dinosaur chess" and "Chess with Maurice Ashley". We liked both of them, too - however I feel it is better to get "No stress chess" first and then the computer games.
