Lego Hidden Side is a range of Lego sets that, as the name suggests, features a hidden element to them. No, it's not a minifig hidden in a cupboard, but virtual ghosts and ghouls that are only revealed when seen through your smartphone.

That's right, Lego has embraced the world of augmented reality and created a number of sets that come to life as long as you've got the right technology.

The accompanying app offers a series of puzzles, the chance to see a virtual world and, when you can take the set with you, the opportunity to carry on playing on the go. There are two game modes including "Play as a Hunter" mode, where the aim is to catch ghosts in competition against other players either online or in the same room, and a "Play as a Ghost" mode (coming 2020) where kids can join two other online ghost players with the aim of haunting LEGO Hidden Side sets and hiding from a player-controlled ghost hunter.

Here we explore Lego's Hidden Side range, what's available, and show the best prices to buy it.

All good ghostbusting stories have to have a lab in which your eminent professor can work from and this is the starting point for the Hidden Side universe. Called J.B's Ghost Lab, it's an entry-level set that features a couple of minifigs, a "de-haunting" chamber and token pizza to munch on why you work out what to do next.

70421 El Fuego's Stunt Truck

Lego El Fuego's Stunt Truck

Amazon

If graveyards and shrimp boat wrecks are too reminiscent of 1980 horror movies on the Maine coast, then you could opt for a more "petrol fuelled" experience with the Stunt Truck. You actually get two vehicles in this set. A three-wheeled motorcycle is the vehicle for a ghost, while the good guys can jump in the souped-up pickup truck complete with working canon.

Newbury Subway

Newbury might be set in the countryside, but that hasn't stopped Lego from creating a city subway station for it, yeah we're not sure behind the logic either. Still this Lego set comes complete with a haunted workman minifig.

Lego 70423 Hidden Side Paranormal Intercept Bus

Our pick of the Hidden Side range is this school bus, which is a pretty solid set for play aside from using the Hidden Side app.

The most iconic Hidden Side set is the battle-ready school bus that features a slide-out ghost hunting lab and a number of minifigs including possessed road workers and their monster toilet. As with the other sets, there is a boss ghost to find and defeat and when you aren't playing with the AR app you'll enjoy driving your minifigs to school, imaginary or not.

70424 Ghost Train Express

Lego Ghost Train Express

Amazon

Hogwarts has a train so why not Newbury High? This American-style express train sees the cab turn from innocent-looking train to a glow in the dark monster train, but it also comes with a portable lab and mini platform waiting room to complete the set. But you will need more Lego train track if you're planning to take a journey anywhere.

Lego Newbury Haunted High School

Amazon

The "hero" set of the Hidden Side range, this haunted high school set features 1,474 pieces, seven minifigs and a miniature "ghost" dog.

Haunted Fairground

Another 2020 set, Haunted Fairground takes the premise that no horror story is truly complete without a clown, and that's exactly what this set delivers. It comes with fairground rides, five minifigs including too scary clowns to play with.

Lighthouse of Darkness

New for 2020 and keeping with the seaside theme; why are so many of the 1980s horror movies set in Maine or on the north east coast of America? The Lighthouse of Darkness is a 540 Lego piece set that features a lighthouse keeper, pier, and a skeleton in the closet. There's a jet-ski included, but you just know that this would and the Wrecked Shrimp Boat set would make a perfect match.
