Arrow Domino is actually a maze puzzle game app. The object is to tap on one of the arrows within the grid and somehow get all the arrows to tumble down, like a string of dominos lined up. Why is this game classified as a maze? Because the essential questions are where does it need to start and where will it exit?
Some arrows: topple 2 neighbors or 4 neighbors.
Some arrows: skip its neighbor.
There are 108 levels and they're not hard. I did them all relatively quickly.
