Jumbo Building Blocks Mega Set – 288 PC – Large Blocks for Kids

Unleash even more limitless creativity with our Biggo Blocks 288-Piece Mega Set! Perfect for kids ages 4–8, this extra-large set is made for young builders with big dreams — and lots of friends to build with. With 288 jumbo building blocks in six bold colors — red, blue, yellow, green, black, and white — this set is your child’s ticket to building massive forts, sprawling castles, obstacle courses, and life-size creations. Ideal for birthday parties, classrooms, large families, or neighborhood playdates, the 288-piece Mega Set turns group play into an unforgettable adventure.

Each color includes 48 blocks: 40 large and 8 small. With our built-in 5:1 ratio and generous quantity, this set gives kids the freedom to create complex builds with the right mix of stability and flexibility. The size and shape are perfect for small hands, and the lightweight plastic makes stacking easy and safe for kids ages 3 and up.

Whether you’re a parent looking to supercharge a playroom, a teacher building collaborative learning spaces, or you want to build something for a party or event - more pieces mean bigger possibilities. This Mega Set is built to grow with your needs, plus, it’s compatible with all other Biggo Block sets, so the creative potential only grows with your collection.

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 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. Whether it's sunny-day stacking or rainy-day building, Biggo Blocks are built to last and easy to clean.

If you’re looking to fuel creativity, encourage teamwork, and support larger-than-life imagination, the Biggo Blocks 288-piece Mega Set delivers. 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.
