Anki Overdrive

What was the No. 1-selling toy on Amazon this holiday season? The Elsa doll. And if you know how popular Frozen is, that makes the sales of the No. 2 toy, Anki Drive, even more impressive.

The AI-powered racing game with Hot Wheels-style robot cars you control with your smartphone is a smash, and now it’s getting an upgrade. Due this September for $150, Anki Overdrive will feature a modular track system that gives users the ability to snap pieces together quickly with magnetic connectors and design the racetracks of their dreams. And maybe the coolest feature will be the 180-degree track piece (sold separately) that, when an Anki car reaches the end of it, automatically sends the car spinning into an about-face, before it motors back to the direction it was coming from.
