It’s been years since LEGO’s original connector design patents expired, allowing other companies to create perfectly legal, LEGO-compatible bricks—as long as they don’t use the LEGO name.
Cheaper Options Without Compromising Fun
Brands like COBI, MEGA, and Sluban offer sets that cost significantly less than LEGO’s equivalent models, while still maintaining impressive design quality.
Massive Savings in Bulk Purchases
Loose, generic bricks can cost a fraction of the price of official LEGO bricks. For example, 1,500 LEGO pieces might run $130, while compatible versions cost just $25.
Ideal for Large Builds and Classroom Projects
Using cheaper bricks for hidden or structural parts of a build can save hundreds of dollars. They’re also perfect for large-scale projects like school dioramas or exhibitions.
Unique Bricks and Colors Not Found in LEGO Sets
Some alternative brands create unusual shapes or rare colors that LEGO doesn’t offer—opening new creative possibilities for builders.
Seamless Integration With Existing LEGO Collections
Compatible bricks can be mixed with genuine LEGO pieces without confusion, making them great for testing designs before committing to premium parts.
Perfect for Custom MOC Prototyping
Builders working on “My Own Creation” (MOC) designs can experiment with cheaper bricks during the trial-and-error stage, then swap in LEGO pieces for the final model.
Lower Risk for Breakage or Loss
Cheaper bricks are ideal for public displays, collaborative projects, or experimental builds where pieces might be damaged or lost.
Encouraging Competition in the Brick Market
Supporting LEGO-compatible brands fosters competition, improves quality, and keeps prices in check for consumers.
Expanding Into Themes LEGO Doesn’t Cover
Alternative brands like COBI produce sets for military vehicles, while Mega Bloks tackles franchises such as Star Trek and Masters of the Universe—topics LEGO avoids.
