Drop Drop! S comes from Adem KAYIRCI. It's a point scoring game.
The object is to drag the 3 pieces onto the board to match colors and score points. The pieces fall upwards from the bottom. Each match yields points, the tiles disappear and you're ready for the next round.
Adem is definitely one of the more interesting puzzle app developers who is still going strong. I particularly liked his game cohex (see link below).
