It’s been a busy few days here in Las Vegas at CES 2026, but I’ve managed to find the time to spend about an hour trying out Lego’s biggest change to its iconic brick since 1958. That change takes a very familiar form.

Lego has unveiled new high-tech “smart bricks” it says will bring its classic toys to life with lights, sound and interactive movement.

The new brick looks and clicks into place like a regular one but its advanced electronics sense other smart bricks and minifigures and respond with real-time audio or light effects.
