Solve the puzzle by revolving the colors across and around until you have complete rows of the same color.

To begin playing, click PLAY.
To see the 'rear side' of the puzzle, click "Rear view".
Use the arrows at the top of the cylinder (remember: it's lying on its side) to shift whole rows up or down.
Use the arrows at the upper side of the cylinder to move a row down a space, and the ones at the bottom to move them down a space.

Good luck!
