As you can imagine, the name “Rubik’s Cube” is registered. So this is the “IQ Brick Cube”. And if you were having trouble solving the original, expect to spend countless hours with this. Featuring one regular sized layer, there are then 7 or 9 extra layers which are much thinner. Being no mathematician, we calculate this increases the complexity a few million-fold. And although it looks almost impossible to solve, there apparently is a method to make things easier.
Both the 3X3X7 and 3X3X9 models are $27, available from Brando.
