Objective: Pack the following six pieces into the box using a 2-unit wide hole at the bottom left of the box. The red square piece must be placed at the top left corner of the box as shown by the dotted outline.
Design Concept: This puzzle is based on the idea in Restricted Zone puzzle. The six pieces move in a way quite similar to Restricted Zone except the space in the box is now rectangular. I wrote programs which work together with Bill Cutler’s programs to discover this design.
