Bought for my little 4-year-son already accustomed to a Sterio. The game instructions are very clear and immediately understood by the child; Only complaint informative details given at each stage including a 4 year old child does not see the interest and make him lose patience. It would be interesting at first to be able to zap and then reintroduce them later. May be more suited to a curious child, 6 or 7 years.
