Here's the title screen. The background color changes as far as nothing happens. Note the Rubik's Cube title which differs from Video Cube.


 
The game can be played in two modes and two speeds.

Normal speed: Player 1 switch set to Easy.
Faster speed: Player 1 switch set to Hard.
Speed can be changed at any time.

Normal mode: Player 0 switch set to Hard.
Cheat mode: Player 0 switch set to Easy.
Colors can only be changed in Cheat mode, and slices can be rotated only in Normal mode. It is possible to change the mode at any time.

Use the Fire button to switch between options: "Turn Cube", "Pick Face", and either "Pick Color" (Cheat Mode) or "Turn Slice (Normal Mode). Use the four joystick directions to turn the cube, pick a face, change the color of the selected face, or turn the slice of the selected face.


The game has a special Solve option which will solve the cube. However, colors must not have been changed. Any face whose color has been changed using the cheat mode must be restored to its initial color. It is not possible to swap colors even if the cube can still be solved.

If the Solve option is tried after one color is changed, a yellow background will appear to warn the player that the option cannot be used.

There is no way to restore the colors automatically.

The Solve option (available when colors are not changed) can be turned on using the Game Select switch. It is possible to return in play mode using this switch.

The Cube will be solved in step-by-step mode, either in normal or fast speed depending on the position of the Player 1 switch.

When Fire is pressed constantly, the cube solves by itself until Fire is released.
When solving, the program shows the direction of each rotation performed.
The normal mode lets you rotate a slice once you have selected a face. The rotation is done in a quite smooth way. Since there are 6 possible rotations for 4 joystick directions, the program must show the direction of the rotation. This is done by 3 color shifts from faces to faces until the desired configuration is reached.
