﻿ I'm stuck!

# The Ultimate Solution to a 3x3x3x3

## Still Stuck?

Here are a few more sequence descriptions sans images which may help you in some of the trickier situations.  Since I'm not providing images, I recommend trying these on a pristine, test instance of MC4D to see what they do.

### Flipped Edges

A flipped edge has one color placed correctly while the other two are switched.  With a slight modification to the third three-color series, you can make a sequence to flip edge pieces.  The following sequence actually flips a pair of edges.

 Top, 4, Left Left, 6, Left Top, 4, Right Right, 4, Right Top, 4, Left Left, 6, Right Top, 4, Right Right, 4, Left

### Twirled Corners

A twirled corner has one color placed correctly while the other three are in a 3-cycle (it is impossible to have a twirled corner in isolation on the 4D cube, similarly to how one can not have a single unsolved corner on the 3D cube).  With a slight modification to the first four-color series, you can make a sequence to twirl two corners.
