I posted on here a long time ago a little blurb about this game. However, I think it needs some overdue credit for saving several therapy sessions in a pinch. I love its sheer simplicity. Namits are all key chain categorization games made with super durable cards. They are perfect for traveling between schools and take up very little space.
I only own this one version of the series, which I picked up two years ago at Goodwill. I had no idea what it was, but I can now say that it was worth every penny of the .99 cent price tag. It's one of my most used therapy items for 2-5th grade.
