Let’s start with the basics. It’s all about automation: fish start biting as soon as you approach them, and resource indicators keep you informed while you focus on managing your Fish Kingdom effectively. The game offers advantageous upgrades to enhance your idle fishing abilities, helping you become a true fish tycoon. You’ll still need to steer your boat to chase fish schools and avoid obstacles, so don’t get too distracted by your economic prowess!

UPGRADE YOUR FISH KINGDOM

Once your hull is full, it’s time to get upgraded! Improvements in fishing speed let you catch more and rarer species, while increased storage capacity allows you to hold more catches in your boat. Boost your boat’s speed and defense for impact protection, and enhance your fishing rods to cast multiple lines at once. It’s all about maximizing your gains in the most efficient way, so you’ll have to use your head to figure out the best way to success!

MAKE IT BIG

Just like in real life, becoming a fish tycoon involves various ways to profit from your catches. The Idle Fish Farm allows you to invest and get passive income, while the Black Market lets you upgrade your Fish Kingdoms beyond OSHA standards. The Bots Shop enables you to hire hunter, fisher, and cargo ships to fish and deliver catch for you, boosting your income. If day trading is your thing, there is a Currency Exchange that has some special benefits. Tax fraud is not a crime, it’s an obligation if you want to make it big.

NOW GO FISH

сам не знаю как, но меня это подзатенуло

abandoned game that is giga imbalanced, becomes a waiting simulator literally 20 minutes after start and the content is not even released properly, or at all. only thing that the developer worked on is how to monetize as much as possible it seems because buying any equipment will save you around 500 hours instantly (not even exaggarating, its just that much of a difference) just so you can reach content that is not finished so you did that for nothing stay away from this as far as you can

Actually a pretty fun idle game, some active elementals but very fun. The last achievements are just such a long grind if you do it F2P... otherwise you have to hit the steam markets to open chests ;/ But not required, so overall a fun game!
