Which Plus-Plus blocks are best?

Plus-Plus blocks are construction toys that allow users to build endless possibilities from a single shape. Every brick interlocks with the next to create simple colorful mosaics or complex 3D shapes. Plus-Plus blocks are made in Denmark using 100% green energy from wind power.

The name Plus-Plus comes from their unique shape, which looks like a jigsaw puzzle piece. The blocks look like one “plus” sign stacked on another “plus” sign. This design allows the Plus-Plus blocks to easily connect to the next in endless combinations. If you are looking for a big set of mini blocks for kids ages 5 to 12, take a look at the Plus-Plus 1,200 Piece Open Play Set and STEM Construction Toy.

What to know before you buy Plus-Plus blocks

BIG Plus-Plus blocks

BIG Plus-Plus blocks are made for kids from ages 1 to 6. The larger size of BIG Plus-Plus blocks makes them easier for small hands to grasp and manipulate. They help children develop fine motor skills, focus and patience.

Mini Plus-Plus blocks

Minis are smaller-sized Plus-Plus blocks designed for older kids ages 5 to 12. Mini blocks measure ¾-by-½ inch. Minis are easy for large hands to work with and are not for little kids because the pieces are small enough to swallow.

Set size

Some of the smaller Plus-Plus sets have 15 pieces but most have 60 or 70. Small numbers of pieces is an indication that the Plus-Plus set is made to build a single toy or figure, such as a penguin, dinosaur or snowboarder. Sets with more pieces are usually designated as “open play.” The largest Plus-Plus set has 7,000 pieces.


The nearly 1-foot-tall clear plastic tubes hold all the pieces inside that you need to make the figure of your choice. The tubes keep all the Plus-Plus blocks in one place and are travel-friendly.
