You can choose any size of cube (or brick) up to 6x6x6, but only one side can have dimension 1 (otherwise the puzzle becomes trivial). The easiest puzzle is 2x2x1 and 3x3x1 is a good warmup for the original Rubik's Cube, which is 3x3x3. Simple puzzles have 2 to 5 shuffling moves, a difficult 3x3x3 puzzle has 10 to 20 --- or you can choose zero shuffling then shuffle the cube yourself, maybe for a friend to solve.
The other options determine whether you can watch the shuffling and/or your own moves and how fast the animation goes. The bevel option affects the appearance of the small cubes. Try setting it to 30 and you'll see what we mean.
