We first saw Anki Overdrive, the company's follow-up to the hugely successful robot toy racing game Anki Drive, we were already amazed at just how much more advanced it was in comparison to its predecessor.

A modern day take on Scalextric, you control a car that is free to race around a vinyl race track. The difference to the traditional toy from Hornby, however, is that the cars have a life of their own. They can not only control themselves, but also fight back with virtual weapons. Overdrive is like a real-world Mario Kart, if you will.

The trouble with the original Anki, however, was that unless you had a massive lounge to roll out the huge track you were pretty much scuppered. Anki Overdrive rectifies this issue with modular track pieces - where, instead of a giant mat to lay out, different pieces clip together magnetically to create any shape of track you like.

We can safely say that Overdrive is a huge leap forward for the Californian start-up. It is almost a complete overhaul of the original Anki Drive in every way, and all of the additions will appeal to kids and more mature gamers alike. But has Anki fixed all the problems of the first game's outing in Anki Overdrive?

You get two cars in the box (Ground Shock and Skull) allowing you to play against a friend. Assuming you've both got a smartphone or tablet (you'll need one per car/player - with up to four on the track at any one time), otherwise you can play against an artificial intelligence (AI) computer opponent instead. The cars are capable of learning the track once you're set up and ready to go.

Anki Overdrive is not just a physical game though; it blurs the boundaries between real-world and virtual by smartphone or tablet integration. Download the iPhone, iPad, or Android app, connect the cars via Bluetooth, and then you can not only start racing, but start shooting virtual weapons that affect the physical cars' response on the track.

Anki Overdrive is all about track pieces that snap together with magnets. The starter kit comes with eight pieces - four straight and four curved sections; plus a couple of plastic supports so you can create a bridge - and that's enough to let you create eight different track designs to race around.

The track pieces are malleable and adaptable - we included everyday objects to help give us height in sections, such as kids building blocks, some Lego, a couple of school books, even a Welly boot.

There are limitless track layouts you can create if you buy add-ons to the starter set. There's a range of different options like more straights, more curves, a jump, a cross-over, and a dead end - with prices ranging from £10 to £30. The jump is definitely worth the extra cash.

The small Anki cars are lightweight, come with a camera hidden beneath to be able to read the track and therefore know exactly where they are. They can get confused at times, though, and will spin off the track much to everyone's frustration.

The lightweight design means they can whizz around the track with some speed, even flying off the jump section with some height. The cars aren't anywhere near as fast as Scalextric, though, but still fast enough that you can come off the track if you don't drive carefully.

In addition to Ground Shock and Skull there are various additional cars to buy, but they do cost £50 a piece. Big Bang is a beefy growler of a vehicle and the chunkiest of the bunch, while Guardian is a police car which gives us all kinds of ideas of how extra game modes could be added at a future date - pursuit anybody?

Each car has its own unique weapon type that can even be changed by earning new items and add-ons during play. Our favourite is a shock blast that creates a dangerous sphere around the car using it, so even if you are above or below the vehicle (like under a bridge) it will still damage your opponent's car, and the speed boost feature that's great for long straights. Different tracks therefore suit different cars and their different skills.

Each car lasts around 20 minutes of racing before needing to recharge, but that only takes another 5-10 minutes to charge again.

There are a number of different game modes for Anki Overdrive, bridging the divide between traditional console gaming and slot car racing. As you would expect there is the standard first over the finish line racing, but where it gets interesting is the other game modes Anki offers.

Super long tracks are great for Battle mode, which is the tried and tested mode for the game. Your car has to shoot opponents as much as possible, with the
