AgeOfBattle

Browser Adventure: AgeOfBattle needs a tab and nothing else. Taps and swipes are the whole vocabulary — a phone plays it best. Its tags here are 1 player, action, battle, best games, hypercasual.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. It costs nothing and asks for nothing: no registration, no download, no launcher.
