More than a simple ball, Thumball™: Category Mania stimulates the skill of efficient word recall, while expanding vocabularies and increasing shortterm memory function.

Printed on each panel of a Thumball™ is a word, graphic, photo or logo relating to a specific subject. Toss it in your hands and read what is written on the panel beneath your thumb. Answer for yourself or ask another player the question. For example, if your thumb lands on "Insects," you could answer with "Beetles."

Educational and entertaining, these soccer-style balls are soft, safe and easy to toss and catch.

Measures 4" in diameter.
