Cast off and walk away.
Hit ▶ Cast Off — your boat fishes on its own. No clicking required.

⚖️ Mind the hold
Your hold is measured in kilograms, and a fish must fit entirely or it slips away. Sell at any harbour to keep space free — every merchant pays full price.

🏪 Spend your gold
Rods, bobbers, bigger boats and bait, all in the Market. Bait is stocked island by island — you can only buy an isle's lures once you've actually reached it.

🗺️ Sail onward
Four isles await, each hiding rarer and heavier quarry than the last.

🔬 Build the empire
Feed your best catches to the Research Hall for permanent upgrades, and spend hard-won levels on Mastery tree.

⏳ Slow by design
Expect an hour or two per meaningful upgrade — and note nothing happens while game is closed. Leave it running and it keeps fishing.
