Advanced strategies and spoiler-free advice to maximize your profits and efficiency.
Special customers will occasionally visit with specific dish requests. Prioritize these quests! Completing them usually rewards you with new recipes, decorations, or significant cash bonuses.
Complete the ecological research tasks given to you. They are relatively easy to finish during your normal dives and reward you with valuable research points, which you can use to unlock permanent upgrades.
In the restaurant menu, use the 'Auto-Supply' option for your dishes instead of putting all your ingredients on the menu at once. This prevents you from wasting ingredients if you don't sell all the portions, as unsold prepared dishes are thrown away at the end of the night.
The layout of the Blue Hole changes slightly each dive, and as you progress, you'll unlock deeper biomes with entirely different marine life. Make sure to explore thoroughly to find rare ingredients required for high-end dishes.
Shooting fish with a lethal weapon reduces their star quality. To get 3-star fish (which yield more meat), try to catch them alive using the Hush Dart (tranquilizer) or the Net Gun. You can also use the Salvage Drone for large sleeping fish.
