As such, I gave hundreds of intelligence tests to children and adults. These cubes are nearly identical (sans the color) as the intelligence test blocks. The block challenges can be obtained via your smartphone or a downloaded PDF file. The block design challenges are excellent cognitive building exercises for children and adults. I highly recommend these blocks for fun and staying mentally sharp. Review: A must-have for children - I ordered this for my granddaughter. I had a set like this when I was young that was made of painted wood. I absolutely loved it and spent hours making different pictures and patterns. When I first took it out of the box, I confess that I spent a bit of time playing with this one. This is not only a fun toy, but it is great at fostering both creativity and thinking skills. The toy comes with a link to get patterns to copy, and that is great. Free play with it is also great to let the child discover her own patterns and pictures. I did count down one star because of a production glitch. This set is (I'm nearly sure) 3D printed. While most of the blocks are fine, a couple of them are not lined up well where the blue and white triangles meet. These are off in some places by a couple of millimeters. I do believe this set is very durable and my grandchildren love it. I would definitely order this again and I highly recommend it. ## Features - ✓ IQ test preparation and examination : individuals can be examined using Block patterns which are used in WISC, WAIS, WPPSI and BDT. - ✓ Self-assessment : the cubes can be used for psychological assessments, testing cognitive growth and problem-solving abilities. - ✓ Brain training : excellent for creative thinking, training imagination, eye-hand coordination and colour and shape recognition, and improving both IQ and EQ. - ✓ Downloadable conten : Each box contains link to downloadable PDF file with 60 block designs. - ✓ Free App included : Mobile (Android/iOS) and Windows 11 app with unlimited patterns.
