What is LEGO SMART Play?

LEGO SMART Play is a new interactive building platform that brings physical LEGO creations to life through the power of the SMART Brick. Instead of relying on screens or apps, this system uses built-in sensors that react to movement and play, making builds respond in real time. The SMART Brick is designed to be fully compatible with existing LEGO sets, so you can add interactive behavior to your current collection without starting from scratch.

Who it's for

• Young builders – Kids who love hands-on play and want their creations to move, light up, or react without needing a tablet or phone.
• LEGO enthusiasts – Fans of existing themes like City, Technic, or Creator who want to upgrade their builds with sensor-based interactivity.
• Parents seeking screen-free fun – Adults looking for engaging, tech-enhanced play that keeps children away from digital devices while still offering modern, responsive features.

Key features

SMART Brick with built-in sensors

The core of the platform is the SMART Brick, a programmable brick that contains motion and touch sensors. When your creation is moved, tilted, or bumped, the brick detects the action and triggers a response—like activating lights, sounds, or motorized movements. No coding or screen is required.

Screen-free interaction

Unlike many modern toys that rely on smartphone apps or tablets, LEGO SMART Play is completely screen-free. All interactions happen through physical play—shaking, rolling, or tapping your build. This keeps the focus on tactile creativity and real-world engagement.

Compatibility with existing LEGO sets

The SMART Brick and its accessories are designed to work with standard LEGO bricks and plates. You can integrate them into any existing set, from a LEGO City fire station to a Creator 3in1 dinosaur, adding a new layer of responsiveness without buying a whole new system.

What stands out

"LEGO SMART Play proves that the best kind of smart toy is one that doesn't need a screen to be brilliant."

While many interactive toys demand a phone or tablet to function, LEGO SMART Play keeps the experience purely physical. The SMART Brick's ability to sense movement and respond in real time turns static builds into dynamic playthings, yet it remains fully compatible with bricks you already own. This blend of modern technology and classic LEGO building is what sets it apart—no apps, no batteries for the sensors, just pure, responsive creativity.

Worth checking out if…

You want to add a new dimension to your LEGO building without abandoning your existing collection. If you're tired of screen-based toys but still want your creations to feel alive, LEGO SMART Play offers a refreshing middle ground. It's also ideal for families who value open-ended, imaginative play enhanced by subtle technology—where the brick reacts to you, not the other way around.
