Swing is a computer puzzle game, released for the PlayStation and PC, developed in Germany by the now defunct Software 2000.
Released in 1997, the object of the game is to score points by dropping balls onto sets of see-saws, in rows of three or more of the same colour.
The twist, however, is that each ball has a different weight, determined by the number written on the front of it.

[2] In 2008, a Java open source remake was made named XSwing Plus and released under GPLv2 and CC BY.
