I think there are a lot of kids that play this game. Probably more than most people realize.
My friends 4 year old grandson plays with her and absolutely loves it. He badgered her for ages until she could afford to buy A BIG TRUCK to put on the farm. She and I hid our leprechauns for ages after St Patrick's Day for him to find. It didn't take too long before we simply couldn't out smart him anymore
