Screen shot of Free WinShuffle's Block Jigsaw using large blocks.  Back

Large square version.

A block  is picked up with the mouse, left hand button down , and moved to anywhere within the frame. When you let go of the mouse button it replaces the square you were over and that square goes to the old Position.

The picture above shows a block being moved, its the one approx. in the middle, moving up and to the right.
