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

Normal 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 block you were over and that block 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.
