Kubrick is based on the famous Rubik's Cube(TM) puzzle. In Kubrick, the cube sizes range from 2x2x2 (easy) up to 6x6x6 (very hard), or you can play with irregular "bricks" such as 5x3x2 and "mats" (one cubie thick) such as 6x4x1. The game has a selection of puzzles at several levels of difficulty, as well as some demonstrations of pretty patterns and solution moves. It is also possible to make up your own puzzles.
