Las Vegas: At CES 2026, The LEGO Group unveiled the LEGO Smart Brick, a fully functional miniature computer embedded inside a standard 2×4 LEGO brick, marking the most significant evolution of LEGO’s core play system in nearly five decades.
Branded as “Smart Play,” the new system transforms the iconic plastic brick into an interactive device by integrating advanced electronics, including sensors, processing power, sound, lighting, and wireless communication—while preserving LEGO’s familiar form and tactile experience.
Unlike traditional bricks, the Smart Brick is powered by a custom-designed 4.1mm application-specific integrated circuit (ASIC), smaller than a typical LEGO stud.
The chip runs a dedicated Play Engine that interprets motion, orientation, and magnetic fields, effectively serving as the brain of the tiny computer.
Inside the Smart Brick, engineers have packed an accelerometer, light and sound sensors, a miniature speaker with an onboard synthesizer, and an LED array.
These components allow the brick to detect movement and positioning, then respond with real-time, context-aware lighting and sound effects, rather than pre-recorded audio clips.
The Smart Brick operates within a broader ecosystem that includes Smart Minifigures and Smart Tags, each carrying a unique digital identifier.
Using near-field magnetic communication, the brick recognizes specific figures or tags and adapts its responses—triggering different soundscapes, light patterns, or interactive sequences based on gameplay context.
Connectivity is handled through BrickNet, LEGO’s proprietary wireless system built on Bluetooth technology. BrickNet allows multiple Smart Bricks to sense each other’s distance and orientation, enabling coordinated behavior between different parts of a model—without requiring smartphones, screens, cloud services, or external controllers.
To support these features, LEGO developed a new wireless charging solution, allowing multiple Smart Bricks to be charged simultaneously on a custom pad.
According to the company, the internal batteries are designed to retain capacity even after long periods of inactivity, ensuring stored sets remain functional when revisited.
Notably, LEGO has deliberately avoided screens, apps, cameras, AI, or internet connectivity during play.
Interaction remains entirely physical—tilting, tapping, or moving a build triggers responses. For example, a vehicle can generate engine sounds as it rolls, while completing a challenge may prompt celebratory audio cues.
Tom Donaldson, Head of LEGO’s Creative Play Lab, said the goal was to enhance creativity without replacing hands-on play, keeping children engaged in building rather than passive digital consumption.
The first Smart Play products will launch on March 1, 2026, starting with three LEGO Star Wars sets:
Darth Vader’s TIE Fighter (473 pieces)
Luke’s Red Five X-Wing (584 pieces)
Throne Room Duel & A-Wing (962 pieces)
Each set will include at least one Smart Brick, Smart Minifigures, and Smart Tags to unlock interactive features such as engine sounds, lightsaber effects, and iconic musical themes.
Fully compatible with existing LEGO pieces, the Smart Brick fits seamlessly into standard builds, ensuring that innovation does not come at the cost of LEGO’s signature open-ended, tactile creativity. With Smart Play, LEGO is bridging classic construction with interactive technology—redefining its iconic brick for a new generation while staying true to what made it timeless.
