Short answer: Mega Construx is not a brand, it is the micro-brick line Mega makes for older builders, and the same parent name also covers a preschool big-block line with completely different scale. Most bad purchases come from ignoring the line name and the age grade on the box, not from picking the wrong brand.
Why the naming is messy
- The company was founded in Montreal, Canada, in 1967 and started in preschool big blocks under the name Mega Bloks.
- A micro-brick line for older builders was later split off under the name Mega Construx to separate the two catalogues.
- In February 2017 Mattel folded Mega Bloks and Mega Construx under a single MEGA master brand with a purple logo, so packaging shows old and new naming side by side.
- Today one shelf can show "MEGA", "Mega Bloks" and "Mega Construx" at once, and they do not mean the same product.
The history above comes from the English Wikipedia entry for Mega Bloks and the Mattel press release of 2017-02-10 that it cites, checked 2026-11-03.
The hard difference between the two lines
- Preschool big blocks (Mega Bloks) — clearly larger than standard bricks, close to Duplo scale, rounded edges, aimed at small hands and safety. Not the same format as standard bricks.
- Micro bricks (Mega Construx) — standard brick format, generally clutches onto LEGO, with looser consistency. This is the line adult builders actually use.
- Figures — Mega Construx micro-figures are not classic minifigures; they carry more articulation and hold poses.
- Themes — licence-led. Halo, Pokémon and Call of Duty are core; original in-house IP is thinner.
Part counts, age grades and recommended retail prices differ by set, batch and region, so check the official product page for the set you are considering. This article deliberately quotes no figures that would go stale.
Four checks before you pay
- Read the line name, not the brand. Look for "Mega Construx" or the preschool wording on the front of the box; "MEGA" alone tells you nothing.
- Read the age grade. Micro bricks skew older. Confirm before buying for a young child; do not assume all bricks are equivalent.
- Check whether the set has functional parts. Figures and vehicles with mechanisms take longer to build and to tune.
- Check part supply. A missing Mega piece usually means another box, so plan for it before starting a large MOC.
Who should start with Mega Construx
- You want one specific licence. LEGO does not make those themes, so Mega is the only route.
- You want a poseable figure to photograph. Articulation is the line's real strength.
- You have a limited budget but want play features. Licensed Mega sets usually undercut the LEGO equivalent on price.
- You want a large pure-display scene. Weak fit. Tolerance variance compounds as the model grows.

One trap worth naming
People read "micro bricks" as "smaller pieces" and assume they interchange with LEGO's small parts. In practice "micro" here means standard-format bricks, used only to separate this line from preschool big blocks. Buyers regularly open a box and find the parts bigger or smaller than expected because of that word.
FAQ
Is Mega Construx still in production?
Yes. It was folded into the MEGA master brand from 2017, so packaging changed while the line continued. Release cadence and current models are best checked on the official channel.
Can Mega Construx and Mega Bloks be mixed?
No. The two use different block scales; the preschool line is much larger. Mixing only makes sense between micro bricks and standard bricks.
Which line suits a six-year-old?
Read the official age grade rather than inferring from the brand. Start with the preschool line for younger children; micro-brick sets generally carry a higher age grade because of small parts.
