Biggo Blocks aren’t just fun — they’re powerful tools for learning and development. As children build, they boost fine motor skills, strengthen spatial reasoning, and engage in hands-on STEM learning — all while staying active and screen-free.
Made for both indoor and outdoor play, the Mega Master Builder Set goes wherever your imagination leads. Built from tough, weather-resistant plastic, it’s ready for backyard play, classroom fun, and every rough-and-tumble adventure in between.

With bold color, endless building potential, and enough pieces for a whole crew of creators, it transforms any space into a supersized playground of ideas.
Worried about where it all goes? Don’t be. Biggo Blocks stack flat like bricks and, when arranged wall-style, take up just 4 inches of floor space. They’re light, nest neatly, and can be slid under beds, stacked in a closet, or even repurposed into furniture or a DIY toybox — they’re strong enough to hold toys, books, or stuffed animals. Big on creativity, smart on storage.

Care Guide

Keep your Biggo Blocks looking new by cleaning them regularly. Simply wipe them with a damp cloth and mild soap. Avoid harsh chemicals and abrasive cleaners that can damage the blocks or fade the colors.

How to store your BiggoBlocks

There are several ways to store BiggoBlocks.
The first is to build a rectangular box to keep all the other toys in. It's a built in toy box!
Another solution is to build them in a straight wall up against your existing wall. They will only take up 4" of floor space!
If you need them out of site, build a straight wall and carefully tip it over and slide it under a bed.
