The LEGO Group says it will introduce a new “SMART Play" system in 2026 designed to make brick-built creations respond to how children move, hold and imagine with their toys.

The Smart Brick looks very similar to a normal 2x4 Lego brick, but it contains a custom Application Specific Integrated Circuit (ASIC) chip which is smaller than one of the studs on the brick itself. It’s joined by an accelerometer and a copper coil, and Lego has created its own Play Engine and Neighbor Position Measurement (NPM) system.

The new sensor-packed Smart Play Brick will land this spring as part of a special Star Wars collection. The update adds interactive lights and sound to the Lego experience—including the minifigs.

Put a Star Wars tag near the brick and suddenly your X-Wing's engines purr. These include classics like Luke's X-Wing, a TIE Fighter, and the Throne Room Duel — all with interactive engine sounds, lightsaber hums, ambient effects, and even theme music moments as you move pieces around.

LEGO unveiled Smart Play at CES 2026, embedding interactive tech into bricks. The first Star Wars sets launch March 1, with preorders Jan. 9.

Lego has unveiled new digital “smart bricks” that light up, emit sounds and respond to movement in its “most revolutionary innovation” in nearly 50 years.
