LEGO officially retired the Boost theme from production back in 2022, and that’s the first thing worth knowing before anything else in this review: the 17101 Creative Toolbox is no longer a current LEGO Shop release, but as of this check it’s still being sold new by third-party retailers on Amazon and remains findable through secondhand marketplaces like BrickLink — so it’s a real, buyable option in 2026, just not a permanent one. For a kid who’s outgrown Botley 2.0’s screen-free sequencing and is ready for actual app-based programming with physical LEGO building at the center of it, that combination is still hard to match, retired label or not.
What’s in the box
The set ships as 847 pieces (some retailers list it as ~840 — the count varies slightly by source, so treat it as “around 840-850” rather than an exact figure) built around three electronic components: the Move Hub, which houses Bluetooth connectivity plus an internal motor and tilt/orientation sensing; a separate Interactive Motor; and a Color & Distance Sensor. LEGO targets the set at ages 7-12, which is older than Botley’s 5-and-up range and reflects the more advanced building and programming involved. Instructions cover five distinct buildable models rather than one fixed design, and the electronics move between all five as a kid disassembles one build to start the next.
The five models
Vernie the Robot is the flagship build — over 10 inches tall once assembled, with the most complex mechanism of the five, including a shoulder-mounted, spring-loaded shooter that fires when triggered by rotating Vernie’s head. M.T.R.4 (Multi-Tooled Rover 4) is a tank-tread rover that swaps between four different tool attachments, one of which is also a spring-loaded shooter. Guitar4000 stretches out to roughly 16 inches and adds pitch-bend and sound-effect controls through the app, functioning as an actual playable instrument rather than a static build. Frankie the Cat is the closest thing in the set to a pet-simulation toy — it plays, purrs, and shifts what LEGO’s own materials describe as “mood” based on how it’s handled. Autobuilder is the odd one out and arguably the most conceptually interesting: a small automated production line that physically builds miniature LEGO models on its own once programmed.
How the coding actually works
The LEGO BOOST app uses an icon-based, drag-and-drop programming interface — no typed code — built around loops and variables, which is a genuine step up in programming-concept depth from Botley’s linear step-sequencing. LEGO’s own materials describe more than 60 built-in activities across the five models, plus an included physical playmat and wall poster that extend a handful of the challenges beyond the screen. The app is tablet-only by design (LEGO never built a phone-sized interface for Boost), and the compatibility list matters more here than on most kids’ tech since this is a retired product: iOS needs 10.3 or later, Android tablets need Bluetooth Low Energy 4.1 or higher (4.0 may connect but won’t take firmware updates), and several Chromebooks that support Android apps and Bluetooth LE also work. LEGO discontinued Windows support for the Boost app entirely — an existing Windows install may keep functioning, but a fresh install on a Windows device isn’t a supported path, which is worth checking against whatever device is actually in the house before buying a retired set you can’t easily return once opened.
Where it fits against the site’s other picks
LEGO Boost sits at the top of this site’s kids-coding-toy tier by both price position and programming depth: unlike Botley 2.0, it requires a compatible tablet to function at all and offers no screen-free mode, and unlike Snap Circuits Jr.’s pure circuit-building focus, Boost is squarely about sequential and conditional programming logic layered on top of physical building. Against Osmo Genius, the split is in what “building” means — Osmo uses the iPad’s camera to react to physical pieces a kid arranges in front of it, while Boost’s models are self-contained LEGO builds that a Bluetooth hub drives directly, with no camera involved. A kid who has already worked through Botley’s sequencing concepts and wants the next step up into loops, variables, and multi-model building is the target buyer here, not a first-time coding-toy purchase.
Honest cons
The discontinued status is the honest headline concern: because it’s no longer LEGO-manufactured, buyers are dependent on existing retailer and secondhand stock rather than a guaranteed restock, and LEGO’s own customer support and replacement-parts pipeline for a retired set is a real step down from a current release. Independent reviews and buyer feedback also flag app stability and battery-life complaints on some tablet/Bluetooth combinations, which is a bigger risk here than on most current kids’ tech precisely because there won’t be many more firmware updates coming to fix it. The five-model format also means constant disassembly — a household that wants to keep Vernie built and displayed permanently will need to buy the pieces to build a second model rather than reusing the same electronics, since the Move Hub and sensors move between builds rather than staying put.
Verdict: who should actually buy this
LEGO Boost is the right pick for a 7-to-12-year-old who has outgrown screen-free coding toys like Botley and is ready for real loop-and-variable programming logic paired with hands-on LEGO building — the five-model format and 60-plus app activities give it real longevity for that age range. It’s not the right pick for a first coding-toy purchase, a household without a Bluetooth-LE-capable tablet already on hand, or a buyer who wants guaranteed manufacturer support and easy replacement parts, given its retired status.
Frequently asked questions
Is LEGO Boost still available to buy in 2026? LEGO itself retired the 17101 Creative Toolbox from production in 2022, so it’s no longer a current LEGO Shop release — but as of this check it’s still sold new through third-party Amazon retailers and remains available on secondhand marketplaces like BrickLink, so it’s buyable, just not guaranteed to stay in stock. Check the current listing before ordering rather than assuming permanent availability.
Does LEGO Boost work without a tablet? No. Unlike Botley 2.0, Boost has no screen-free mode — the Move Hub pairs over Bluetooth to the LEGO BOOST app, and every model needs that app connection to be programmed and controlled.
How is LEGO Boost different from Osmo Genius? Osmo Genius uses the iPad’s camera to detect and react to physical pieces placed in front of the screen, while LEGO Boost’s Move Hub connects directly to the LEGO models over Bluetooth with no camera involved — they’re both tablet-dependent, but the underlying mechanism is completely different.
What age range is LEGO Boost actually built for? LEGO’s own target is 7-12, noticeably older than Botley 2.0’s 5-and-up range, reflecting both the more complex builds (Vernie alone stands over 10 inches) and the deeper loop-and-variable programming concepts in the app versus Botley’s linear step sequencing.
