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.

Rubik's Cube can be moved into many interesting patterns. Here are a few from David Singmaster's classic book 'Notes on Rubik's Magic Cube, Fifth Edition', pages 47-49, published in 1981. After a pattern has formed, you can use the Solve action (default key S) to undo and redo it as often as you like.

<qt>Mathematicians calculate that a 3x3x3 cube can be shuffled into 43,252,003,274,489,856,000 different patterns, yet they conjecture that all positions can be solved in 20 moves or less. The method that can do that (as yet undiscovered) is called God's Algorithm.<br><br>Many longer methods are known. See the two Wikipedia articles on Rubik's Cube and Optimal Solutions for Rubik's Cube.<br><br>Several methods work systematically by building the solution one layer at a time, using sequences of moves that solve a few pieces without disturbing what has already been done. The 'Beginner Solution' demonstrated here uses that approach. Just over 100 moves solve a cube that is shuffled in 20.</qt>
