Circa 2000-2005ish. The goal was to swap bouncy balls to match vertically and horizontally so they would bounce away. Does anyone know the name and if it still exists? They would wiggle when matched then appear to pop off the board as they fell forward. The sound effects had lots of squeaky bouncy ball noises. It may have been on a site called free internet arcade.
Update: my husband just informed me this isn't DOS, so I apologize.
