It's all in the wrist! Use the mouse to control your view of the cube. Left click on a colored anchor point (hollow square) to select that color. Once selected, you can paint that color onto the empty (grey) squares.
Connect each pair of colored anchor points by creating an unbroken path of the same color from one to the other.
- Paths must be created by connecting adjacent squares (no diagonal paths!).
- Remember to leave room for more difficult (farther) connections when making making the simple (close) connections.
