What is LEGO Smart Play?
The battery arrives ready for play with some charge left in it, which is quite a feat in itself given that the method of turning on the battery is to shake it. Charging takes about 2 hours, and will last 45 minutes of solid continuous full usage e.g. using lights, sound etc all at once. If that sounds short to you, consider that 45 minutes is a long time for most children of the target age group (which seems to be fairly youjng as one set is age-marked as 6+) to stay focused on one play activity.
Which LEGO sets have SMART Play?
Is LEGO Smart Play too basic?
- The models are primarily for play, not display
- Obvious and stable handholding points are needed given the additional swooshing that will go on
- Given the increased rough nature of play, small items and greebles that would fall off have not been included, as children tend to cease play to fix models in those situations
- Bold colour areas are included for clarity of placement of the LEGO Smart Brick

Fact sheet
LEGO SMART Play is a new interactive platform where technology seamlessly brings LEGO sets to life, responding to actions with appropriate sounds and behaviours, allowing for a truly responsive play experience, all without screens.
The combination of LEGO SMART Play’s platform elements – the LEGO SMART Brick, LEGO SMART Tags and LEGO SMART Minifigures – react in real time to bring an interactive play experience to kids and are the most significant evolution in the LEGO System-in-Play since the introduction of the LEGO Minifigure in 1978.
Developed by the LEGO Group’s Creative Play Lab team, the new platform features more than 20 patented world-firsts within its technology, and the LEGO SMART Brick – the ‘play engine’ at the heart of the platform – is powered by a custom ASIC chip, allowing its electronics to be miniaturized to such a level, that they fit within the iconic footprint of a 2x4 LEGO brick, which allows kids to seamlessly add interactivity to their LEGO builds.
THE COMPONENTS OF LEGO SMART PLAY
LEGO SMART Play is a platform that integrates advanced invisible technology that encourages intuitive, imaginative play without screens or the need for detailed instructions.
The LEGO SMART Brick is packed with technologies that bring play to life including sensors, accelerometers, light sensing and a sound sensor as well as a miniature speaker driven by an onboard synthesiser, and much more, in addition to easy wireless charging.
LEGO SMART Tags and LEGO SMART Minifigures are paired with the LEGO SMART Brick to power the system and allow builders’ creations to become interactive, responding to actions with appropriate sounds and behaviours, allowing for a truly responsive play experience. All elements are compatible with the existing LEGO System-in-Play.
ABOUT THE LEGO SMART BRICK
The LEGO SMART Brick is at the heart of the LEGO SMART Play platform, turning LEGO builds into interactive experiences:
- The LEGO SMART Brick is the same area as a regular 2x4 brick, designed to fit with any existing elements in the LEGO System-in-Play.
- Contains a compact electronic system built around a custom mixed-signal ASIC chip. At 4.1 mm, the chip is smaller than a standard LEGO stud.
- ASIC chip runs a bespoke Play Engine which interprets motion, orientation, and magnetic fields in real time, bringing LEGO creations to life like never before.
- The chip is integrated with a precision copper coil assembly that enables the LEGO SMART Brick’s near-field magnetic positioning and tag recognition.
- A proprietary Neighbour Position Measurement (NPM) system uses precision copper coils to let LEGO SMART bricks sense distance, direction, and orientation between multiple LEGO SMART Bricks.
- Series of modular synthesisers produce real-time audio, minimising memory load.
- Miniature speaker is acoustically tuned through internal air spacing to amplify and clarify sound within the LEGO SMART Brick’s enclosure.
- Responsive audio effects are tied to live play actions; there are no pre-recorded clips.
- Accelerometer detects movement, tilt, and gesture, triggering context-specific reactions to how creations are being played with.
- LED array provides ambient light response and colour sensing for dynamic visual feedback.
LEGO SMART TAGS & LEGO SMART MINIFIGURES – BUILT TO SENSE
LEGO SMART Tags and LEGO SMART Minifigures trigger sounds, lights, or behaviours tied to placement or interaction.
- Each 2x2 studless tile LEGO SMART Tag carries a unique digital ID read by the LEGO SMART Brick through near-field magnetic communication.
- Works like contactless tech, engineered for toy-grade safety and precision.
- LEGO SMART Minifigures look identical to standard minifigures but include an internal chip carrying a unique digital ID detected through the same magnetic process.
BRICKNET – BUILT TO CONNECT
The secure wireless layer that lets multiple LEGO SMART Bricks act together:
- Bluetooth-based BrickNet protocol shares data between LEGO SMART Bricks with low latency.
- Uses Neighbour Position Measurement (NPM) data to recognise each LEGO SMART Brick’s position and orientation, offering Brick-to-Brick positioning.
- MPS fosters rich, spatially aware play; the distributed network of interacting LEGO SMART Bricks can talk to each other directly - no app, central hub, or external controller required.
- Enhanced encryption and privacy controls, meeting the high safety standards of the LEGO Group.
LEGO SMART PLAY – BUILT TO LAST
- The LEGO SMART Play system is engineered for power efficiency, resilience, and ease of maintenance.
- Battery designed to support real play patterns; will still perform after years of inactivity.
- Custom coils and power system allow for one-to-many wireless charging; charges several LEGO SMART Bricks simultaneously on a shared pad.
- Firmware updates and diagnostics are handled via the LEGO SMART Assist app.
TECHNOLOGY WORLD FIRSTS
The new platform has been developed by the LEGO Group’s Creative Play Lab team, in collaboration with Cambridge Consultants, the deep-tech powerhouse of Capgemini, and manufactured by JABIL. The platform features more than 20 patented world-firsts. At its heart is the LEGO SMART Brick, powered by a custom ASIC chip.
The patents unlock a roomful of technology, shrunk into the iconic LEGO brick. Without any setup, SMART Bricks are magically ‘aware’ of each other’s positions and orientations in 3D space, thanks to a novel, high-accuracy, magnetic positioning system. They can also communicate via a self-organising network that adapts to play. Advanced onboard systems let SMART Bricks comprehend and interact with each other, as well as the fans building with them.
This is an achievement in extreme miniaturisation and hyper-integration of different technologies – with stacks of innovation and many new-to-the-world inventions all squashed down to fun-size.

Being an adult, I only bought the Mario figure out of curiosity and never played with it, I wonder if kids really did, and really wanted this.
ReplyDeleteAlso, as an adult again, I'm pretty sure the brick won't be any programmable (at least without hacks) (because LEGO), and thus useless for MOCing.
Meanwhile the competition is doing things that people have asked for (buildings with lights). It still looks like LEGO isn't any interested in LED lighting, while the side market for that clearly exists.
But again, I'm adult and I'm sure LEGO did their homework testing out this thing with kids. But... they supposedly also did this with Vidiyo...
I think it's pretty obvious why Lego wouldn't want something like this programmable—you don't want people programming in inappropriate sounds and then an unsuspecting kid getting that secondhand.
DeleteBut I don't know if that makes it "useless for MOCing" since you could easily use, say, a helicopter tag for a helicopter MOC or a car tag for a car. Yes, the sounds will only be the ones that go to the tag in question, but that's really no different from previous sound bricks that were set-specific.
I think those Bricks also work standalone just work the RFID Tiles. I actually used one of the write able RFID Dimensions parts to store information for a birthday present. May be there will be times that can be written. I mean we had great sound bricks before (Alien abduction sound) Gate opening from Agents, now this is all in one Brick. I think it is great. I just hope the thingy is not blinking all the time and control with the Tiles can make MOCs interactive.
DeleteWell, as far as I know, there are no MOCs that use existing sound bricks, except for the alternatives of the sets that the sound bricks were included in. Isn't that inconvenient for MOCing?
DeleteThey said it plays audio and lights based on the tags. So in theory, one could customize the tags to play any sound. They might try to lock these down, but if there is a way to put firmware updates on these, then there is a way to fully unlock and cusomize the brick's behaviour. If we only manage to make lights blink in a certain way, that already unlocks a ton of MOC possibilities. Looking at the PyBricks project, I am quite hopeful about all of the situation. (Can't wait for these to go on sale though)
DeleteGenerally all the light and sound configurations would be preloaded into the main chip (in the brick, in this case) and then the tags trigger specific ones, they aren't reading files stored on the tag chips. So the most you'd likely be able to do is make duplicates of existing triggers, unless you can find some hidden files or funny jailbreaks. I had a thing like this with some Phantom Menace figures I'd gotten at the time, they included a little stand/chip that you could tap onto a reader and it would cycle through 4-5 sound clips related to that character. It was a fun system. "As an adult" it doesn't do much for me, but as a former kid I remember "ooh it lights up!" being a decent selling point on a lot of things, including the initial wave of Exo-Force sets.
DeleteLEGO's newest attempt to force app connectivity into plastic block playsets aside—is that a new astromech droid torso mold?
ReplyDeleteThe app is just to update the brick I imagine.
DeleteThe astromech is a new element, I believe it has a 2x2 SNOT surface on the back for the tag and no studs on the top (connecting the dome with a pin). The X-Wing canopy is also a new element with a very interesting shape, so I'm interested to see that analysis.
There was no mention of an app during the conference, yes there might be one for updates, charging, brick status etc. but it seems like all the play features are standalone and screen-less. Refreshing to see among everything else at CES.
DeleteIt would be great if something on this web page explained what the technology actually does. It's kid of hilarious that nothing here does -- it's all the why and marketing, none of the what or how.
ReplyDeleteit lights up and makes noises, responding to direction and motion with accelerometers. its buried in the marketing stuff, but thats all it appears to do
DeleteIf you have Instagram you can see @zaxbrix Stories with clips of the live demo.
Deletehttps://www.instagram.com/stories/zaxbrix/3803575924215141961?utm_source=ig_story_item_share&igsh=OTAwdmNkaWlic3oz I'm currently working on adding his clips to this page.
Full video now added to the page, what you're after starts at 5:27 https://youtu.be/co9yCTA9-rE?si=rBU7X-qDDHLJuEne&t=322
DeleteIt also has color sensors and relative positioning to other Smart Bricks and Smart Minifigures, and the behavior can be set with special 2x2 tiles - Smart Tags.
DeleteDo you know when PAB will get updated with new pieces?
ReplyDeleteApparently Lego has had problems with the PAB deliveries lately. (I have one old order still in the warehouse, myself.) Maybe they might postpone the update until the old orders are on track, again.
DeleteMy big question is: Are all of the smart bricks interchangeable? If so, how do they get configured for each specific set that includes them? And if they're just configured by the RFIDs in the plates and minifigs, this opens up some really exciting possibilities for hacking them with custom RFIDs!
ReplyDeleteThey're configured to the plates/figs, but I'm fairly sure that the data on those RFID tags are mainly a simple ID that the brick uses to react appropriately with its own existing internal programming, rather than one that actually contains audio files or anything like that. If so, then you could use a custom RFID to "clone" an existing tag's effect, but you couldn't upload new sound effects or light/sound patterns that aren't programmed into the brick or patched in via the official app.
DeleteA good comparison would be the existing Lego Mario sets, which use colored barcodes for a similar purpose. Mario's behavior isn't coded into the barcodes, scanning those just looks up the appropriate reaction inside Mario's internal data. And when new sets come out with new codes to react to, the digi-fig has to be updated to have new data encoding those reactions and what code enables them.
What I've read, and what Lego has said so far, contradicts this to a degree. The RFID tiles don't include digital audio files (e.g. .wav or .mp3), but they do contain synthesizer instructions, and the Smart brick plays the instructions on its audio synthesizer. It's a bit like MIDI, if you know what that is, but probably at a more primitive level. The instructions probably involve selecting things like wave shape (sine, square, sawtooth, etc), frequency, amplitude, duration, etc, instead of specifying an instrument and note like you do with MIDI. These instructions can be extremely compact, like a few hundred bytes, well within what RFID can handle.
DeleteHm... It would definitely be cooler if that's how it is! I guess we'll see when the sets are out.
DeleteMy only question, which not answered anywhere, is: Is it possible to add own sounds at this smart brick?
ReplyDeleteNo it is not :(
Delete
