The classic building brick of LEGO has taken a significant technological leap with the arrival of Smart Brick and the Smart Play platform, presented officially at the CES 2026 From Las Vegas. Despite the internal overhaul, the piece maintains the same size and shape as the familiar 2x4 brick, so it continues to fit with any existing collection without any changes to the building process. This move undoubtedly represents one of the company's most ambitious technological investments in decades.
What exactly is the Lego Smart Brick?
The call Smart Brick is a standard 2x4 brick From the outside, it blends in with any other LEGO system element. The difference lies within: it houses a silicon ASIC chip just 4,1 mm thick, custom-designed for this platform, which acts as the "brain" of the entire Smart Play ecosystem.
This chip integrates motion, light and proximity sensors, RGB LEDs, a small speaker and wireless radioas well as an internal rechargeable battery. All of this is assembled while maintaining the mechanical precision of the interlocking system, so that the brick can be placed in any model without compromising stability or the building experience.
One of the key components is a coil This allows the brick to identify nearby smart tags and minifigures, as well as measure its distance and orientation relative to other Smart Bricks. LEGO calls this capability Smart Bricks. Neighbor Position Measurement (NPM), since the system develops a kind of "spatial awareness" of its immediate surroundings.
To power all this electronics, the Smart Brick incorporates a rechargeable battery via inductive chargingThe company has opted for a system similar to that of an electric toothbrush, so that the bricks can be placed on a charging base in virtually any orientation to recover energy.
This approach makes it easier for The battery recharges without needing to physically access the brick.Even if it's completely surrounded by pieces inside a spaceship or building, LEGO assures that the system has been designed to maintain reliability after long periods of inactivity, a key factor in toys of this type.
A hardware-centric system, without screens or cloud.
Unlike other connected toys that rely on apps, cameras, or cloud services, LEGO has opted for a radically different approach: The entire Smart Play experience relies on local hardware.There are no cameras, no voice capture, and no cloud-hosted artificial intelligence models are used to manage interaction.
Communication between the different elements is carried out using a proprietary protocol called BrickNetwhich operates as a low-latency local wireless network. This system, based on radio technologies similar to Bluetooth, allows Smart Bricks, labels, and minifigures exchange encrypted information about identity, position and status, without going through external servers.
In practice, this means that No app or screen is needed to playThe brick interprets its surroundings in real time using magnetic detection and integrated sensors, and responds with light and sound effects directly from the physical model. Firmware updates are managed through an official app, but everyday gameplay remains completely offline.
Smart Tags and Smart Minifigures: how reactions are activated
The Smart Play ecosystem is organized around Three main elements: the smart brick, the Smart Tags, and the Smart MinifiguresEach of these pieces incorporates a unique digital identification that the Smart Brick reads when it is brought near or placed in specific positions.
The Smart Tags function as event triggersThese can represent anything from a vehicle to a turret or a control panel, and when detected, the system activates specific effects such as blaster fire, engines, or alarm signals. Meanwhile, the Smart Minifigures add other extras, with differentiated reactions depending on the character, their state and the relationship with other nearby elements.
During the demonstrations at CES, the media reported that scenes were shown in which The bricks reacted to cars, helicopters, or moving figures.When a minifigure was moved up a ramp, the system emitted engine and braking sounds; when a collision between characters was simulated, crash effects or emotional expressions were reproduced. This logic was later applied to the Star Wars sets, where the movements between ships and characters generate more complex sound sequences, such as the roar of the engines of an X-Wing or a TIE Fighter, the whirring of lightsabers or recognizable musical fragments that are activated at key moments, such as when Darth Vader is seated on his throne.
Below you'll find a video from the channel. Beyond the brick so you can get a better idea of ​​how it works because it's worth seeing:
From theory to practice: the Smart Play platform
Lego describes Smart Play as the result of nearly a decade of research and user testingWith a clear objective: to introduce advanced technology without overshadowing the traditional physical gameplay. The development of their own ASIC, wireless charging, and brick position measurement are all results of this process.
In interviews, the design team has insisted that The technology had to be "invisible".In other words, everything digital has to run in the background, following the rhythm of the game, without requiring the child to look at a screen, open an app, or interact with menus. The focus remains on building, moving, and experimenting with the physical pieces.
Furthermore, to reassure families, the company has emphasized that There are no cameras, no audio is recorded, and no sensitive data is sent to the cloud.BrickNet uses encryption in communications between bricks and labels, and update functions are limited to specific times managed from the official app, as we have indicated.
Still, The new range of products has generated some debate among experts in children's play.Critics point out that children are already capable of bringing their creations to life through imagination, without the need for digital lights and sounds, and fear that a growing reliance on technology will diminish the importance of pure creativity. The company, for its part, insists that the system is designed to integrate seamlessly into existing sets and that interactivity complements, rather than replaces, traditional storytelling.
Star Wars as the first major showcase for Smart Play
For its commercial launch, the Danish firm has opted for one of its most powerful licenses: LEGO Star Wars It becomes the first line to incorporate smart bricks and figures. The collaboration with Disney and Lucasfilm results in an initial wave of three sets designed to showcase different capabilities of the system.
Among them are a Luke Skywalker's Red Five X-Wing with 584 pieces, Darth Vader's TIE fighter with 473 pieces and a wider set that combines the Emperor's throne room with an A-Wing fighter, totaling 962 piecesAll include at least one Smart Brick, plus smart minifigures and tags that activate specific sequences.
In X-Wing, for example, the movement of Luke or Leia over different sections of the hangar It triggers engine sounds, gunfire, signal lights, and even refueling or repair audio. In Vader's TIE Fighter, the focus is on the roar of the twin ion engines and the interaction between the fighter and a small Rebel outpost.
The throne room and A-Wing set aims for a more atmospheric dimension: The movements of Luke, Vader, and Palpatine trigger dialogues, lightsaber whirring, and recognizable musical motifs., like the famous Imperial March when the villain takes his seat as you may have seen in the video above.
Prices, bookings and availability in Europe
LEGO has set a clear roadmap for the arrival of Smart Play to the market. Reservations for the first sets open on January 9thThe official launch is scheduled for March 1, with an initial distribution focused on selected markets.
In terms of prices, the company places this first wave in a mid-to-high range: Star Wars references range approximately from $70 to $160, with euro equivalents of around 69,99 euros for the smallest set and 159,99 euros for the largest, according to the first international listings.
In Europe and Spain, we imagine that sales will be conducted through the brand's usual channels, including Lego.com, own stores and major distributorsFurthermore, it is known that some "All-In-One" packs will include from the outset a smart brick with charger, at least one Smart minifigure and a Smart tag, so that the complete system can be used without purchasing additional accessories.
