TomZ – designer of other awesome puzzles like the proportional 4x4x6 – teamed up with Calvin’s Puzzle in 2018 to bring us the Constrained Cube series. There are different variations of the constrained cube but this Ultimate version has a mixture of constraints on each face. Some faces can only rotate 90 or 180 degrees while the white face can’t rotate at all! This puzzle really makes you think outside the box on how to go about solving it because some of the algorithms you might normally use are no longer possible.
