Mindflex Duel is the greatest party game ever!

If your kid wants a Mindflex or that Jedi Mind training thing, the one where you strap on headgear then "pilot" your ball through a maze? Skip it, pay a little more and get the MindFlex Duel instead. You can still play solo, BUT you can also play head-to-head, almost literally, as you essentially play tug-of-war with your concentration. The only issue is that people won't believe it works. But it does, and it is a lot of fun.
