Eat or be eaten as you play as a fish stuck inside an Apple Watch (or an iPhone)! The Apple Watch game works best for Apple Watch Series 4 and up. Works OK on Series 3. Steer your fish fin by turning the Apple Watch crown back and forth. Or swipe on your phone. Avoid being eaten by bigger fish and get bigger by eating smaller fish. And there might just be a jellyfish or two lurking in the deep.
