In the beginning choose one of 16 figures or, using the built-in editer, create one. The figure, chosen or created by you, is broken into some fragments of any form. Fragments mix up on the game field. Your task is repair the source figure. You can move and rotate fragments, but can't break and weld them. During game you can see a figure shadow on the field and get a sample. Repaired figure must equal to a sample shadow, but can be placed anywhere.
