Halloween Connect Puzzle

Halloween Connect Puzzle is listed here under Puzzle. There is no launcher and no install between you and it. Taps and swipes are the whole vocabulary — a phone plays it best. Catalogued as halloween, mahjong, matching, puzzle.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Everything runs client-side, so there is nothing to set up before you start.
