LAS VEGAS—Lego’s newest Luke Skywalker mini figurine can make lightsaber sound effects all on its own. The Lego Group is making its CES debut by launching a new lineup of toys called Lego Smart Play. The main piece is the Lego Smart Brick, which has a variety of sensors and can change colors and emit sound effects to match the play scenario. A Lego Smart Tag snaps onto it and provides the code, and both interact with new Lego Smart Mini Figurines.

To help launch the lineup, Lego is adding to its Star Wars collection with new smart sets that will debut in March. The sets include an X-Wing set with a Luke figurine, a TIE fighter set with Darth Vader, and a Throne Room set where the two can have a lightsaber duel.

Even outside the Star Wars universe, Lego’s press demo showed the Smart Brick used in a variety of games and demos. Two bricks changed color to match a nearby board, or based on how close they were to each other. They emitted swooping and crashing sound effects when attached to a plane and car figurine. Smart figures let out a comical cry when a car crashed into them.

The bricks themselves will have sound, light, color, and distance sensors. They look like ordinary rectangular Lego bricks— clear when turned off, and displaying a variety of colors when turned on, depending on the scenario. The Smart Tags are small rectangles that plug into the middle of the bricks. You then shake the brick to wake it up. It wasn't clear from the demo whether you'll need a different Smart Tag for each scenario, such as plane sounds and animal sounds.

The possibilities of the bricks did seem cool. The location sensing allowed the presenters to play a game with kids, and the bricks changed the colors of participating cars based on which one was rolled closest to a target.

The Smart Tags could be the main limiting factor. When I was a kid, I was pretty adept at making the lightsaber sound effects myself while dueling against Vader. The company also didn’t specify pricing or how often you'll need to recharge the various pieces. Still, the goal of increased immersion seems within reach, and Lego wants to integrate technology into its toys in a way that enhances physical play away from screens while being intuitive to use.

We’ll aim to try out these toys in our offices and in a galaxy far, far away once they’re released. In the meantime, check out all the rest of the cool tech we’ve seen at CES.

My Experience

I’m PCMag’s senior writer covering smart home and wearable devices. I’ve been reporting on tech professionally for nearly a decade and have been obsessing about it for much longer than that. Prior to joining PCMag, I made educational videos for an electronics store called Abt Electronics in Illinois, and before that, I spent eight years covering the smart home market for CNET. 

I foster many flavors of nerdom in my personal life. I’m an avid board gamer and video gamer. I love fantasy football, which I view as a combination of role-playing games and sports. Plus, I can talk to you about craft beer for hours and am on a personal quest to have a flight of beer at each microbrewery in my home city of Chicago.

The Technology I Use

I tend to like mixing flavors from various companies. My personal computer is an Apple MacBook Pro. My phone is a Google Pixel 7a. On my wrists are an ever-rotating lineup of the latest smartwatches, and I sometimes wear two at once for testing and extra style. The Apple Watch Ultra 2 is a mainstay on my wrist because I use it as a control for evaluating the accuracy of other devices' fitness metrics. 

I spend plenty of time in front of my entertainment center, which features a 55-inch LG OLED TV, a Yamaha soundbar, a Nintendo Switch, and a PS5. (I insisted on getting the PS5 with the disc slot when they were hard to come by and haven’t used the feature in more than a year.) I thought I’d have given in to temptation and snagged an Xbox to play Starfield by now, but Baldur’s Gate 3 saved me money by distracting me long enough for the Starfield hype to blow past.

I have two cats and sneeze plenty, so I have a Shark Air Purifier to help me fight back against their dastardly, shedding ways.

I use my aforementioned Pixel 7a and a Nest Hub for Google Assistant, an iPhone 16e and AirPods to talk to Siri, and an Amazon Echo Show 5 and Echo Show 15 for Alexa, so I’m not in danger of losing touch with any of the big three digital assistants.
