At CES 2026, LEGO unveiled one of its most exciting innovations in recent years: the LEGO Smart Play system. While many media outlets refer to them as “bricks with artificial intelligence,” it's important to clarify. This isn't generative AI or cloud-connected AI, but rather a well-designed combination of sensors, electronics, and wireless communication that allows constructions to come to life… without screens and without collecting data.
And in today's world, this is a decision that is as much technological as it is ethical. LEGO has understood something crucial: children don't need more screens, but rather more physical, creative, and interactive experiences. Smart Play is precisely in line with that.
From the outside, the new bricks look like regular LEGO pieces. They maintain the same size, the same compatibility, and the same core philosophy: build, imagine, and play. The difference lies within.
With Smart Play, a construction is no longer static. It can react to movement, the environment, other pieces, and figures, generating sounds, lights, and behaviors consistent with what the child is doing at that moment.
Everything happens in real time, without apps, mobile phones, or an internet connection.
The system consists of three key pieces: Smart Brick (the classic brick, modernized), Smart Tags, and Smart Figures.
The heart of the system is the Smart Brick. The central piece is the Smart Brick, a 2x4 brick that concentrates all the system's "intelligence." This is where LEGO demonstrates brilliant design, both technologically and pedagogically.
This brick incorporates:
. Motion and gyroscope sensors, which detect turns, accelerations, or jolts.
. A pressure microphone, which doesn't record audio but reacts to ambient sounds or breaths.
. An LED matrix, capable of changing color or generating light patterns.
. An internal speaker, which doesn't play simple recorded sounds but dynamically generated effects.
. A color sensor detects nearby pieces and adapts to them.
The result? If you place the Smart Brick on a car, it "accelerates" when you push it quickly and "brakes" when you stop. On an airplane, the engine sound changes depending on the tilt. There are no buttons or menus: the control is the game.
The second element of the system is the Smart Tags, small pieces with RFID chips. These tags allow the Smart Brick to recognize objects and contexts.
For example: A gas station tag activates refueling sounds when the car approaches.
Other tags can represent workshops, space stations, runways, or special scenarios.
This introduces a layer of automatic storytelling, where the system itself reacts to the context created by the child.
The third key element is the Smart Minifigures. These figures have programmed identities that interact with the Smart Brick and with each other.
In the first announced line, based on Star Wars, we see very clear examples:
. Darth Vader activates the Imperial March when he approaches.
. Luke Skywalker can trigger lightsaber sounds if he encounters a nearby enemy.
There are no distracting screens: the child listens, imagines, and continues the story in their mind.
LEGO has been very clear on three fundamental aspects:
. No screens: no mobile phone, tablet, or app is needed during play.
. Total privacy: no cameras, no sound recording, and no data transmission.
. Wireless charging: batteries designed to last for years, charged on a simple base.
The first sets will arrive in March of this year, with a clear intention to integrate this technology into future lines.
A profound change? Probably so. LEGO isn't trying to compete with video games or tablets. It's doing something much smarter: enhancing the physical toy with invisible technology.
If the Smart Play system is widely adopted, it could mark a new era in educational and creative toys. Without media hype, without digital dependence, and with a very clear idea: for children to keep playing… but with more possibilities.
Time will tell how far it goes. But the direction certainly seems right.
