As you scramble it, you introduce colors in 1-bit RGB.

In particular, two opposite faces of the cube have the letter R on them, two opposite faces have the letter G on them, and two opposite faces have the letter B on them.

These letters are put on the center square of each face.

You can rotate just like with a Rubik's Cube. You can also tap a face to toggle the color bit indicated by the letter on the face.

For example, tapping on a face with R would toggle the red bit on all the "stickers" on that face.

To solve the puzzle, you need to get it back to all black.

Do you think this would make an interesting puzzle?
