We tend to hate it when toymakers add apps and other teched-out elements to old-school products. Often, the tech elements feel extraneous. Not so with this Hot Wheels set. A standard side-by-side racetrack with a nice loop-de-loop, the Hot Wheels Augumoto uses augmented reality to up the ante of a regular race. Players control the two rechargeable cars with their phones via Bluetooth, firing missiles and laying down tar slicks to slow their opponents. Augmoto marries the best of Mario Kart with real-world fun in a way that works shockingly well.
