Start a Run
Open the homepage and press Start. The game begins at level 1 with a target score, a time limit, one boat, and one net. Your job is to catch enough valuable sea items before the timer reaches zero. When you clear a level, the game moves forward and gives you an upgrade point.
You can play in solo mode or switch to duo mode. Solo mode is simpler and easier for learning the timing. Duo mode adds a second boat, which gives you more control over the water but also asks you to watch both sides of the screen.
Aim Before You Cast
Move the aim marker over the water and choose a lane with a good catch. Do not cast at the first moving object you see. Look for a path where the net can reach a fish, pearl shell, or treasure without passing through a hazard. The net catches one item at a time, so every cast should have a clear target.
On desktop, use the mouse or keyboard controls to aim and cast. On mobile, tap the water where you want to send the net. The game is designed so the main action stays in the first screen and works without downloading an app.
Haul the Catch Back
After the net reaches an item, it hauls the catch back to the boat. Small fish return quickly. Heavier items, such as treasure, move more slowly. That delay matters because the timer continues while the net is hauling. A big reward can be worth the wait, but repeated slow catches can make later levels harder.
Build Combo Safely
Clean catches build your combo multiplier. This is one of the main ways to clear targets faster. A clean run of fish, pearls, and treasure can score more than random casting. Hazards break that rhythm because they can cost score, time, or both.
If you want more detail about points and multipliers, read the Sea Catcher scoring guide.
Watch for Hazards
Dangerous catches are marked with a red warning ring and an exclamation mark. Jellyfish, trash bottles, and sharks are not normal rewards. If you catch them at the wrong time, they can damage your run. Learn their shapes first, then use the red warning effect as a quick signal while playing.
The items and hazards guide explains each catch type and how to treat it during a level.
Use Upgrades Between Levels
When you clear a level, spend upgrade points carefully. A better net helps with reach and catch control. A stronger engine helps the boat move faster. Sonar helps identify safer targets and plan casts. The best upgrade depends on how you play: if you miss often, improve the net; if you feel late to good lanes, improve the engine.
Simple First Goal
For your first few runs, do not chase every treasure chest. Try to clear levels with clean fish catches and only take heavy rewards when they are clearly safe. Once you can reach level 3 consistently, start using more aggressive routes and higher-value targets.
