looks good but
i agree with another reviewer that had same experience, my 5 year old kept racking up the points, but she wasnt actually doing any subtracting. the game is flawed in that its crutches turn it into just a counting game. i had to handhold daughter to make her actually do the subtraction, but then it wasnt fun anymore doing it that way, she just wanted to get the trophies by counting. maybe your kid is different, give it a try if you think so.
