RULES:
BoxOff is a solitaire puzzle game. The object is to clear all the tiles off the board.
Two same-colored tiles can be removed if they share an otherwise empty rectangle.
The order in which tiles are removed determines whether or not the board can be cleared.

Press the "Start Thinking" button to create an initial puzzle setup.

Refer to "BoxOff.pdf" (included) for the complete rule sheet.
