LEGO® SMART Play™ at Argos

The SMART Play™ System is our most revolutionary innovation since the creation of the minifigure in 1978.

Using cutting-edge technology, it responds precisely to how kids play. In other words, when you play, the SMART Brick plays back.

There are three key pieces that work together:

The SMART Brick. A 2x4 LEGO® brick that recognizes SMART Tags and SMART Minifigures. It also has a built-in accelerometer which knows how it is being moved through the air, and brings play to life in incredible ways. 

The SMART Tags. These clever little tiles tell the SMART Brick what it should become, to help it play back with you. 

The SMART Minifigures. When placed next to a SMART Brick, you’ll discover how each SMART Minifigure reacts differently to its environment with unique sounds, moods and reactions – all of which are played through the SMART Brick. 


The SMART Play System shows what happens when high-powered tech meets the limitless creativity of a child’s imagination. With the help of the SMART Tags and SMART Minifigures, the powerful SMART Brick responds to how you play with it, hold it, twist it, turn it... you name it!

It’s also endlessly replayable, because the SMART Tags and SMART Minifigures help unlock unique reactions, secret minigames, plot twists and Easter eggs. The fun keeps on going! 

This is an evolution of the LEGO® System in Play, all SMART Bricks, SMART Minifigures and SMART Tags also click with your LEGO® bricks at home to bring all your LEGO® sets to life!

The SMART Brick can sense the presence of SMART Tags and SMART Minifigures that are close to it. These activate the SMART Brick and tell it how to behave.

Once activated, the high-tech SMART Bricks react to every move, with a built-in play engine that creates limitless reactions with dynamic lights and sounds.

To get started, you’ll need up to three key pieces that work together to create the LEGO® SMART Play™ system: the SMART Bricks, the SMART Tags and the SMART Minifigures.

For example, out of the literally endless potential play possibilities... Build a helicopter and place a helicopter SMART Tag into it. Add a SMART Brick close to the SMART Tag. Now your SMART Brick ‘becomes’ a helicopter and reacts to how you move and play with dynamic lights and sounds! Hear it take off and fly – or fly it upside down and hear the alarm sound. Add a SMART Minifigure pilot and hear them react!

It’s the brains of the operation.

The 2x4 SMART Brick is packed with enough tech to launch a rocket to the Moon (... maybe if you have a couple of extra rockets lying around...). It has responsive lights, a color-recognition scanner to sense its surroundings, a sound synthesizer that plays almost any sound, and a built-in accelerometer. This detects the way it is twisted, turned and tapped during play.

All this juicy tech means it can react to how kids play – and then play back!

When placed on top of or close to a SMART Tag, the SMART Brick becomes whatever the SMART Tag tells it to. Meaning it can be a helicopter one second and a car the next.

But it also can sense the presence of SMART Minifigures to help bring your stories to life in ways never seen before. The SMART Brick reveals each SMART Minifigure’s unique sounds, moods and reactions.

The SMART Minifigures activate the SMART Brick and prompt it to reveal their unique personalities.

Each SMART Minifigure reacts differently to the world around them. They do that through their own sounds, moods and reactions, which are played back to you via the SMART Brick.

Through the sounds the SMART Brick makes, you’ll be able to tell which SMART Minifigure might enjoy flying through space in a starship. You’ll notice that a more nervous character might be a bit more… hesitant…

And because every SMART Play Minifigure reacts uniquely to any given play scenario, they provide a perfect reward for kids’ imagination and creativity. Which sparks new ideas for role play, every single playtime.

No. Instead, their job is to tell nearby SMART Bricks what sounds it should make. 

SMART Tags make the SMART Bricks behave in a particular way and react using lights and the SMART Brick’s built-in speaker.

SMART Play™ All-In-One sets contain everything you need to start your SMART Play experience, right out of the box.

They contain SMART Minifigures, SMART Tags, a wireless SMART charger and... drumroll please... the SMART Bricks!

This brick is the brains of the operation. It responds to how it is being moved through the air, and reacts to how it is being played with. When combined with SMART Tags and SMART Minifigures, they help tell the SMART Brick how it should play back.

SMART Play™ Compatible sets contain SMART Minifigures and SMART Tags, but do not include a SMART Brick.

These Compatible sets feature the same great build experience as any other LEGO® set, and can be played with for hours and hours (and hours).  

But, when they activate the SMART Brick found in our SMART Play™ All-In-One sets, the SMART Tags and SMART Minifigures will help the SMART Bricks reveal a whole new dimension to the play!

Yes. The SMART Bricks, SMART Minifigures and SMART Tags can be combined with any LEGO® sets we’ve ever made (and ever will make). It’s not a ‘new’ System in Play, but an evolution of it. However, to get your hands on these SMART Play™ elements, you’ll need to buy one of the LEGO® SMART Play sets we’ve released them in.

There are two types of SMART Play sets: SMART Play All-In-One sets and SMART Play Compatible sets. Our SMART Play All-In-One sets contain the SMART Brick, SMART Tags, SMART Minifigures and everything else you need to unlock the full SMART Play experience. Our SMART Play Compatible sets contain great LEGO® building play on their own, and contain SMART Tags and SMART Minifigures which are compatible with the SMART Brick (available in All-in-One sets).
