2) Solve; slide the rect. parts to form a continuous chain of dominoes over and around the ball, matching the point value with the adjacent part(s).
The rectangles can be slid around one corner one-by-one. Note: after several moves and beeing rotated around a corner, a rect part can return to its original position but in a different orientation, ie. rotated 90 deg. sideways.
