UNO Reflex is the latest UNO branded game from Mattel, designed by the Catapult Concepts design team.

It’s not really UNO; it’s It’s UNO plus a speed game. The electronic doodad may display a color and you have to be the first to play it. When you play a wild, the doodad picks a random color. (Update: I just read the rules.)

When the doodad breaks, you can still play UNO with the cards.
