ELOH

Eloh ($2.99) isn’t a rhythm game, but it makes music as central to the experience as that thumpin’ genre. It’a a puzzle game about shuffling stone heads around the screen, the better to bounce streams of sound off them so that they slip into a goal. Sometimes you’ll have to work with different heads; sometimes you’ll have to match differently colored streams with the properly colored idols. A funky beat plays through all of this—even when you’ve bungled it seemingly beyond all hope—but it grows funkier as you approach perfection.
