Halloween Monster Shooter

Halloween Monster Shooter is listed here under Puzzle. There is no launcher and no install between you and it. It is built for touch, so a phone or a tablet is the natural place for it. Catalogued as bubble, bubble shooter, halloween, match 3, match-3.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
