LEGO GROUP Introduces LEGO® Hidden Side™, Combining Building with Augmented Reality to Create a New Way to Play
Company pioneers experience where kids play with one hand in two worlds
NEW YORK (February 14, 2019) – The LEGO Group today unveiled LEGO® Hidden Side™, an augmented reality-enhanced LEGO play theme where kids must turn a haunted world back to normal, one ghost at a time. It is the only play experience available today that fully and seamlessly integrates augmented reality (AR) with physical construction to reveal a hidden world of interactive play. Developed for children 7 years and up, LEGO Hidden Side is showcased to buyers, media and influencers for the first time at American International Toy Fair Booth in Booth 1335 of Hall 3B at the Jacob K. Javits Convention Center, February 16 -19.
LEGO Hidden Side includes a series of eight “haunted” building sets full of awesome functionality and secret surprises that, on their own, provide the build and roleplay fun of any LEGO play theme. Activating the bespoke AR app developed together with the theme brings the models to life, revealing a hidden world of interactive mysteries and challenges to solve. When combined, the two worlds make each other even more compelling and fun.
“Our years of experience pioneering the convergence of technology and physical play have taught us that kids expect exciting play experiences that move seamlessly between physical and digital worlds – something we call fluid play,” said Tom Donaldson, senior vice president, Creative Play Lab at the LEGO Group. “At our core we focus on tactile building, but AR presents opportunities to enhance physical LEGO play with new action and mastery elements. We’re breaking the mold of gaming-first AR play experiences to create a new type of play where the physical world actually influences the AR layer, instead of the other way around.”
Core LEGO Building Experience
LEGO Hidden Side building sets deliver everything kids love and expect from a LEGO building experience – the challenge of the build, a detailed model with functionality, and minifigure characters set in a story-driven universe. Each model can be built as it appears by day – a school house, bus, or graveyard, for example – and has transforming functionality to become the haunted version of itself
Truly Augmented Play
The app lets kids assume a first-person perspective and play together with the two characters – Jack and Parker – as they explore their hometown of Newbury, using their mobile phones to see and solve paranormal mysteries beneath the surface of their environment. Game play prompts kids to hold their phone up to the physical LEGO models and interact with various elements, or “points of possession,” which release virtual ghosts that kids must then capture in the AR game to stop the haunting. Numerous scenarios create dynamic gameplay that requires kids to keep one hand in each world to progress the play.
Donaldson added, “As we have designed LEGO Hidden Side, physical manipulation of the LEGO models alters the AR experience, and the AR experience prompts new things to discover in the physical models, creating a deeply engaging reciprocal play experience in two worlds that has never been seen before.” The app also consists of a digital game that kids can play independent of the building set.
After launch, the app experience will continue to expand with the addition of new ghosts, new game challenges, and randomization of gameplay so the experience is different every time kids play. Donaldson noted, “We’re leveraging some of the best elements of mobile games to keep the experience fresh, encouraging kids to return to their LEGO sets time and again to see what is different. With the thoughtful integration of LEGO building and AR technology, we can deliver a truly innovative play experience that taps into the ever changing landscape of fluid play, where children constantly find new moments and forms of play.”
LEGO Hidden Side will be available globally in late summer 2019. Physical sets will range in price from 19.99 to 199.99 The LEGO Hidden Side app will be a free download from the App Store and Google Play.

![Introducing LEGO® Ideas Grand Piano (21323)
FEEL THE RHYTHM WITH THE SPECTACULAR FAN-DESIGNED LEGO® IDEAS GRAND PIANO SET
Imagined by an avid LEGO builder, the LEGO Group’s brand-new LEGO® Ideas Grand Piano is a show-stopping set for adult music lovers and builders - available from 1st August from LEGO.com and LEGO Stores.
[23rd July 2020] A dazzling idea from a keen LEGO builder and music enthusiast, has now been brought to life after receiving overwhelming demand from the public - as the LEGO Group launches the brand-new LEGO® Ideas Grand Piano™ set. The latest product is part of the LEGO Ideas collection, which conceptualises and produces the creative wonders imagined and voted for by LEGO fans themselves.
Designed with the intricate elements of a real grand piano, this brand-new set is a fully immersive build. With a clever motor and working keys, when the set is combined with the LEGO Powered Up app, fans can become musical maestros one brick and one note at a time - making it The LEGO Group’s first-ever piano set with the ability to play music.
Talented builders can try their hand at creating their own masterpiece on the LEGO® Ideas Grand Piano™ using the LEGO Powered Up app, which allows them full control of the musical notes and piano keys. Alternatively, those looking to sit back and relax can choose to select ‘auto-play’ and enjoy the dulcet tones of one of the ten pre-set songs available.
The brand-new set is a masterpiece of craft and innovation, featuring all the makings of real-life grand piano to give an authentic musical experience in LEGO brick-form. These authentic features include a removable 25-key keyboard, a top lid that can be propped up, an authentic hammer action and a moving damper and pedal, which help to make the LEGO® Ideas Grand Piano™ as beautiful as it is functional.
Once built, the 3,662-piece LEGO® Ideas Grand Piano™ is made to take centre stage as a spectacular display model for any room, measuring over 8.5” (22.5cm) high, 12” (30.5cm) wide and 13.5” (35.5cm) deep when closed.
The new grand piano set is part of the LEGO Ideas collection, which offers fans the opportunity to submit their own brick creations with the chance to have their concept brought to life with the help of LEGO master designers and a share of the profits. Other recent LEGO Ideas sets inspired by LEGO fans, include the LEGO Ideas Pirated of Barracuda Bay and the LEGO Ideas Friends Central Perk.
Imagined by music teacher and LEGO aficionado Donny Chen, this set was designed as a way for him to combine his passion for music with his passion for building. To add to the excitement and personal feel of the build, the LEGO® Ideas Grand Piano™ even features a music sheet composed by Donny himself.
Speaking about the process, Donny Chen said: “When I’m not building with LEGO bricks, I’m teaching, tuning or writing music on my piano. So, when I first discovered LEGO Ideas, I knew I wanted to build something that not only combined my two passions, but also looked visually stunning. It’s truly an honour to see my idea brought to life by the talented people at the LEGO Group and I hope it brings joy to all the other music fans who voted for the idea on the LEGO Ideas platform.”
Federico Begher, VP of Global Marketing at The LEGO Group added: “We get so many amazing concepts submitted through our LEGO Ideas platform, but when we saw Donny’s piano design it really stood out as something extraordinary, with great potential to become a truly unique LEGO set.
The accompanying images and video submitted by Donny really sparked some ideas within the team. We believed that including power functions as part of the model to enable the set to play real music in real life would elevate the design even further. We simply could not pass on the opportunity to create the ultimate LEGO Ideas Grand Piano model for music and LEGO fans alike!”
The new LEGO® Ideas Grand Piano™ set is the latest example of how the LEGO Group aims to inspire builders of all ages to build, rebuild and get excited by the process of creation.
