The Marina Map
Every round is played on the same harbour chart. Knowing where the fish enter, where they turn and where the nest lies is half of a good defense.
The harbour mouth
Every wave enters at the red marker on the left edge. The first stretch is straight, so a heron near the entrance gets an early clean strike.
The winding channel
The channel bends back on itself several times. Berths placed inside a bend reach two stretches of water at once and are the most valuable spots on the chart.
Berths for your crew
Ten round berths sit beside the water. Each holds one defender: a heron, a net or an otter. Tap an empty berth to hire, or tap an occupied one to promote it up to level three.
The nest under the pier
The nest is ringed by a red and white lifebuoy at the end of the channel. Every fish that reaches it costs one heart, and when the hearts run out the round ends.
Waves and calm water
Each wave is larger than the last, and catfish join from the third wave. Between waves there is a short calm with a countdown — the best moment to build and upgrade.
Wide and narrow charts
On wide screens the channel runs across the harbour; on phones it winds from top to bottom. The rules are the same, only the shape changes to fit your screen.
