Danish toymaker Lego this week unveiled three new electronic additions to its classic building blocks at the Consumer Electronics Show 2026, in Las Vegas, that can see some of its creations come to life with sound and light.

The new add-ons will launch in select markets in March in three new Star Wars sets.

At the heart of the new Smart Play System is a new, two-by-four smart block that can detect motion, position and distance, allowing the models to respond in various ways during play.

To do this, the brick – which can charge wirelessly – contains sensors, accelerometers, light and sound sensors, as well as a miniature speaker driven by an onboard synthesiser.

It also has a tiny silicon chip – measuring smaller than a standard Lego stud.

The smart brick was launched along with the smart tag and smart minifigure, the two other members of the Lego Smart Play System, which features more than 20 patented world-firsts.

Lego’s first minifigure was introduced back in 1978.

Also adapted from existing Lego components – and thus highly familiar to users – the smart minifigure and tile have digital identifiers that offer various sounds or reactions when they detect each other.

British news service BBC notes, for example, that it tested out the system at CES 2026, with a Lego birthday cake recognising when its “candles” were blown out, cueing a cheer and a happy birthday song.

One of the Star Wars sets to launch in March – Luke Skywalker’s Red Five X-Wing building set – will be a 584-piece set that will include an Imperial turret, transporter and command centre, all of which unlock interactive features such as laser-shooting sounds, engine sounds and lights, plus refuelling and repair sounds, through the use of the smart brick, two smart minifigures and five smart tags.

Other sets will see fans – kids and grownups (increasingly) alike – unlock features such as the hum of lightsabres with the smart minifigures of Darth Vader and Luke Skywalker, the engine roar of an A-wing, as well as The Imperial March playing when Emperor Palpatine sits on his throne.

Lego promises that the smart platform will continue to expand and grow with new updates, launches and technology.

It says the smart technology has been developed by the group’s Creative Play Lab team to enable “responsive physical play, breathing new life into builder’s Lego creations through advanced, invisible technology”.

“For over 90 years, the Lego group has sparked imagination and creativity in children around the globe,” says Lego group chief product and marketing officer Julia Goldin.

“As the world evolves, so do we – innovating to meet the play needs of each new generation.

“Lego Smart Play is . . . something we are super excited about being able to bring to the world at this scale.”
