Sharkio

Sharkio drops you directly into a crowded aquatic arena where survival is strictly dictated by the food chain. You begin as a vulnerable little fish navigating the murky depths, darting between drifting nutrient pellets while keeping a watchful eye on giant predators gliding across the screen.

Every action revolves around a calculated risk-versus-reward mechanic. As you feed and steadily expand in size, your agility changes and you become a bigger target for rival swimmers. The boost mechanic lets you surge forward to ambush unsuspecting prey or escape a closing jaw, but every second spent boosting bleeds away the mass you worked hard to gather.

For visitors on Tiny Fishing who normally enjoy the quiet patience of casting lines and unlocking gear upgrades, Sharkio offers an intense, immediate change of pace. Instead of pulling fish up to the boat, you are down in the water fighting to stay at the very top of the food web.

How to play

Swimming is mapped entirely to your mouse cursor: guide the pointer across the screen, and your shark steers smoothly toward it. Click and hold the left mouse button to activate your speed boost. Sweep across open water to absorb glowing pellets and swallow smaller fish that swim in your path. Keep your distance from any creature larger than your current frame, as swimming into them results in instant defeat.

Survival tips

Keep your eyes on the edges of the screen. Because camera zoom expands with your size, spotting larger rivals early gives you enough time to turn away before they boost into strike range.

Conserve your boost mass for vital moments. Holding the boost continuously drains your size in seconds. Tap the button for quick micro-bursts only when closing the final gap on prey or escaping a predator.

Scavenge energy after big collisions. When large apex sharks clash and eliminate each other, dense clusters of high-value pellets scatter across the area. Sweep the outskirts carefully to grow rapidly without taking direct risks.
