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.

In the Star Wars sets launching with Smart Play in March, the Emperor minifig will play the Imperial March when you sit him on this throne. Ships can blast at each other with laser noises, and lightsabers will hum and whirl when figures holding them are moved.

Lego made its first appearance at CES 2026 to show off its Smart Brick, which can change colors, make sound effects, and sense other nearby Legos.

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 Lego Group unveiled its new SMART Play bricks at CES, the first building sets, featuring Star Wars, are expected to launch in March.
