Short answer: Mega Bloks is not "cheap LEGO". It is a separate product line that occupies the price tier and the licensed themes LEGO leaves open. Tight budget, wanting a film or game licence, and tolerance to looser fit points to Mega. Long-term collection, unlimited expansion and resale value point to LEGO. Compare those four things, not cost per brick.
First, the identity question
This has to come first, because "Mega Bloks" is often mistaken for a knock-off. It is not:
- Founded in Montreal, Canada, in 1967 — a legacy North American brick maker, not a recent white-label entrant.
- On 17 November 2005 the Supreme Court of Canada rejected LEGO's trademark claim against Mega Bloks and let the product stay on sale in Canada.
- Mattel acquired the company in April 2014; Mega is now Mattel's brick brand.
- In 2008 the Court of First Instance of the European Union also ruled against LEGO's side in a related trademark dispute.
So the legal fight is long finished. Calling every competing brand "fake LEGO" wrecks your own buying judgement before you start.

Four decision axes that beat price
- System and compatibility — LEGO runs one standard brick system that has not broken compatibility in decades, so it expands without limit. Mega runs two lines: preschool Mega Bloks, whose blocks are clearly larger than standard bricks and closer to Duplo scale, and Mega Construx micro bricks, which share the standard brick format and generally clutch together. Those two lines are not interchangeable, so read the line name on the box.
- Tolerance and feel — LEGO's consistency is the industry baseline; two bricks from the same batch feel identical. Mega varies more. An occasional piece in a box sits loose or grabs hard, and mixed builds are where you notice it.
- Themes and licensing — LEGO leans on its own IP plus selective licences. Mega leans on licences, with Halo, Pokémon and Call of Duty among its strengths, and its micro-figures use articulated joints rather than the classic minifigure format.
- Long-term value — LEGO has a deep second-hand market and reliable part supply. Mega's secondary market is thin and single parts mostly come from breaking another box. For long-term MOC work, part supply is a hard constraint.
Pick by situation
- First set for a young child on a budget — the preschool Mega Bloks line. Cheap and hard to break.
- Large scenes, thousands of pieces — LEGO. Part supply and system stability decide it.
- You want one specific licence — check Mega first. If it holds the licence, buy it; LEGO does not make those themes.
- A figure that poses on the shelf — Mega Construx micro-figures articulate further than a minifigure.
- A display piece you keep for years — LEGO. Tolerance and resale are both steadier.
- You want to mix both — fine, but follow the section below.
Where mixing stops working
Micro bricks and standard bricks generally clutch, so the question is not whether but how well. Three rules cover most of it:
- Do not mix brands in load-bearing structure; keep stressed parts in one brand.
- Put the mixed pieces on decorative, non-structural surfaces.
- After long mixing some pieces loosen. Pull the loose ones out before they end up as structure.

One common miscalculation
People reduce the decision to cost per brick and conclude Mega wins. That ratio ignores two costs: part supply, because a missing Mega piece usually means another box, and time, because tolerance variance means re-seating pieces as the model grows. The bigger the build, the more those two dominate.
FAQ
Is Mega Bloks a fake LEGO?
No. It is an independent brand; Canada's Supreme Court rejected LEGO's trademark claim in 2005, and Mattel has owned the company since 2014. Same format is not the same as counterfeit.
Are Mega Construx and Mega Bloks the same thing?
No. Mega Construx is the micro-brick line for older builders, close to standard brick scale. The preschool Mega Bloks line uses much larger blocks. Read the line name on the box, not just the brand.
Will Mega bricks clutch onto LEGO?
Generally yes, with looser consistency than LEGO — some pieces sit slack, some grab hard. Do not mix brands inside load-bearing structure, and treat fit as something to check on the real parts.
