Fish Royale io

Dominate the deep blue ocean and climb the underwater food chain in Fish Royale io! Take absolute command of a hungry, aggressive marine predator locked in a high-stakes multiplayer arena. Your critical mission is to hunt smaller sea creatures, evolve your species, and impale rival players with your sharp horn to become the ultimate king of the sea. Test your swimming precision, dodge giant apex monsters, and rule the ocean depths!

Controls Move your Mouse cursor smoothly across the screen layout to steer and guide your fish in any direction. Click and hold your Mouse Left-Click (or press Spacebar) to engage a sudden swimming speed boost. On mobile, drag your thumb on the virtual joystick to move and tap the dedicated button to dash.

Rules & Strategy You must consume floating plankton and smaller marine life to increase your size, evolve your weapon, and score points. Piercing an opponent from behind or the side instantly defeats them, allowing you to harvest their dropped energy cores. Do not just charge blindly at larger players from the front because their higher-level horns will instantly deplete your health bar. It is highly recommended to patrol the edges of the map to grow safely early on, using your dash exclusively to ambush isolated targets or escape tight traps.
