In The Entropy Centre, Puzzle 0902 is mostly here to introduce you to a new puzzle element, the tall cube. This new type of cube can be expanded by rewinding it, but this comes with a catch: You can’t reposition the cube and then rewind it back to an old location, like you can with other cubes. Rewinding a tall cube will only cause it to unfold. Solving Puzzle 0902 is actually pretty easy once you understand how the tall cube functions. Basically, you just need to use the bridge cube on the button panel rather than the tall cube.
