Lego introduces Smart Bricks for the world's most popular children's toy.

Lego has unveiled Smart Bricks—NFC‑enabled 2x4 pieces with lights, sounds, sensors and Bluetooth networking—and will begin rolling out three Star Wars sets using them on March 1, 2026.

Lego has introduced Smart Bricks, a new 2x4-style piece that contains a tiny updatable computer and NFC chips. The company unveiled the technology at the 2026 Consumer Electronics Show in Las Vegas as part of its Smart Play initiative. Each brick includes lights, speakers, motion and tilt sensors and a microphone used as a sensor rather than a recorder, and bricks can form a Bluetooth network with other Smart Bricks and NFC-enabled tiles or figures. Lego said the first Smart Bricks will appear in Star Wars sets that start shipping on March 1, 2026. What we know: - Smart Bricks look like classic 2x4 pieces but contain tiny computers and NFC chips similar to those used in contactless cards and key fobs. - When placed near NFC-enabled Lego tiles, minifigures or other Smart Bricks, they can trigger lights, sounds and music and react to motion or tilt. - Bricks form a Bluetooth network to interact with each other, and multiple bricks can be wirelessly charged at the same time. - Each brick has a microphone used as a sensor (Lego says it is not a recorder); the company says there is no camera or AI in the bricks and they do not work with Lego Mario tiles. - The first three Smart Bricks sets are Star Wars releases due March 1, 2026, described in company materials with set sizes and prices; Lego called this a major evolution of its System-in-Play and said Smart Play will expand with future updates and launches. Summary: Lego's Smart Bricks add embedded electronics and networking to standard-style bricks, allowing sets to produce lights, sounds and reactive behaviour when combined with NFC-enabled pieces. The company will roll out the first Star Wars Smart Bricks sets on March 1, 2026, and says the Smart Play program will continue to expand; other brand upgrades have been reported as possible but remain unconfirmed.
