About Fish Royale io

Fish Royale io drops you into a crowded reef where smaller fish are food and larger predators are a constant danger. You begin as a guppy, eat smaller fish to grow, and compete for dominance in a changing underwater food chain.

The reef also contains powerful abilities such as laser bursts, drill dashes, and toxic wakes, plus comic-inspired skins. Kelp provides a busy setting for weaving around danger, while fast growth and the global leaderboard give your feeding run a competitive goal.
