Water The Plant

Water The Plant 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. Its tags here are adventure, casual, hypercasual, plant, puzzle.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Free to play in the browser, with no install step between you and the first round.
