IQ Test Cubes (Kohs Cubes)

Kohs blocks are a fun and challenging way to enhance your cognitive skills and spatial reasoning. The set consists of nine identical bicolored cubes, typically red and white, that can be arranged into a variety of geometric patterns.

But they are more than just a fun puzzle. In neuropsychology, they are considered one of the best methods to assess spatial ability and reasoning. They are used in the Block Design Test, a subtest of IQ (Intelligence Quotient) assessments.

Whether for play or cognitive training, you can now print your own set!

Pro tip: You can also download a mobile app to train and measure your spatial abilities.
