Buy it

Her favourite. Good quality, she goes for her bag by holding the strap, takes it to me to open for her them she turns the entire bag over lol. It's good for use. There are no small or harmful parts, they are just as pictured.

Great for learning colors!

These blocks have been great for learning colors with my kiddo. They feel like good quality. The colors are nice and bright. It would also make a great gift for a grandchild niece or nephew.

Perfect for toddlers

Twin 2 year old grandbabies loves these. Perfect for their age, they’re a decent size, and the girls love building with them and even use them to practice saying their colors. It seems to be a decent quality, so no complaints there. Easy for the girls to play with and put together. Worth the money in my opinion.

MegaBlocks for the win.

Grandson approved. He is content for 30-40 minutes with this play set. For 2.5 years old I’ll take it.

Choosing MEGA BLOKS for a toddler: a short buyer's guide

MEGA BLOKS are big, chunky building blocks made for children from their first birthday. Here is how the range fits together, what to buy first and how the sets grow with a child.

What are MEGA BLOKS?

Oversized plastic building blocks with large studs, made for toddlers and preschoolers. They are bigger than standard construction bricks, so they are easier for small hands to press together and to pull apart. The core range is called First Builders.

Which set should come first?

For most families, the Big Building Bag: eighty big blocks in bright colours, with the bag for storage. If two children will share, the 150-piece Deluxe bag avoids early arguments. A child who loves wheels may get more out of a block vehicle.

Are all First Builders sets compatible?

Yes. Bags, tables, vehicles, trains and the 3-in-1 sets all use the same big block, so every new set adds to one collection instead of starting a separate one.

What do the ages on the box mean?

Our shelves are labelled 1+, 1½+ and 3+. The 1+ sets are about grip and stacking, the 1½+ sets add letters, numbers and matching, and the 3+ sets introduce following picture steps.

How many blocks does a toddler need?

Fewer than you might think. Eighty is enough for one child's towers, roads and walls. More pieces start to matter when building turns social, or when a table or vehicle needs feeding.

Is MEGA the same as MEGA BLOKS?

MEGA is the wider family name. MEGA BLOKS is the big-block toddler range; the MEGA collector builds are small-piece display sets for adult fans and are not meant for young children.

LineAge labelSet sizeWhat sets it apart
Building bags1+80 or 150 blocksThe open-ended base of any collection

Block vehicles1+5 to 23 blocksRolls, hauls and stores its own blocks
Learning builds1+ to 1½+30 to 60 piecesLetters, numbers or animals on the blocks
3-in-1 builds3+25 or 26 blocksPicture steps, three models per box

Before you order

  • Check the age label on the set against where your child is today, not where they will be next year.
  • Count the pieces against how many children will share them.
  • Look for built-in storage if tidy-up is a battle in your home.
  • Remember that every First Builders set clicks onto the ones you already own.
  • Keep small-piece collector sets on a separate, high shelf.

Still unsure? Our age guide walks through each shelf, and the compatibility note explains how the sets combine.

People also ask

The questions that come up most when choosing a first block set.

What age are MEGA BLOKS for?

The First Builders range starts at age 1. Learning builds such as the counting bus are labelled 1½+, and the 3-in-1 sets are labelled 3+.

Are MEGA BLOKS compatible with LEGO DUPLO?

We design our blocks to work with each other: every MEGA BLOKS First Builders set clicks onto every other. We don't make claims about other makers' bricks.

How do you clean MEGA BLOKS?

Wash them by hand in warm, soapy water, rinse and let them air-dry fully before they go back in the bag. Our care note has the details.

How many pieces are in the Big Building Bag?

Eighty big blocks, stored in the drawstring bag. The Deluxe Building Bag holds 150.

Does the ABC Musical Train need batteries?

The listing describes music and sounds from the smokestack piece. Check the box or the set page at the shop for the battery details before you order.
