Our children love pullback toy cars: the ones you pull back and then let go to watch them zoom across the floor. Our cats are… less keen. To say the least.

Far safer from a mog’s point of view is to have the pullback racing done on a smartphone or tablet. That’s what Lego’s latest app provides: Lego Pullback Racers. It’s a free game promoting their range of real Lego Technic pullback toys.

Your children have to win races to unlock new levels, while collecting gears to upgrade their vehicle as they go. There are no in-app purchases in the game, so it’s purely about skill.

Lego Pullback Racers is a free download for iPhone and iPad on Apple’s App Store, and also free for Android on the Google Play store.
