If you have a Rubik’s Cube that you haven’t been able to solve and want to “clean it up,” you should check out the free online application at Wrongway.org. Wrongway is a blog run by Eric Dietz out of Minneapolis and includes some very helpful links, including those to solve the standard 3x3 Rubik’s Cube, the more advanced 4x4 Cube, and some general advice on solving the cube on your own. With the simple interface, you color the cube to match your exact configuration, click solve, and a page will be displayed with the step-by-step instructions to solve your cube. It’s quick, simple, free, and effective; all the hallmarks of good software.
