Capture and Release: The capture and release feature is a handy method of quickly and efficiently moving multiple puzzle pieces at a time. Use the "Capture and Release" button in the toolbar to toggle in and out of capture mode. Capture pieces by clicking them, or by swiping over them while pressing the mouse button. Release captured pieces by clicking in any open space of the playing area, or by swiping over open space while pressing the mouse button.
All captured pieces can be released in a stack by releasing the first piece and then jiggling the mouse over the piece while continuing to press the mouse button. A stack of pieces can be captured in a similar manner.
