How to Play Aquarium of Surprises Idle Game
Managing your virtual tank is incredibly intuitive. Here is a step-by-step guide to building the ultimate underwater paradise:
- Watch and Earn: Your fish automatically generate coins as they swim. Check the top bar to track your total coins, income per second, pearls, and current aquarium level.
- Shop & Upgrade: Open the Shop menu to spend your coins. Additional fish of the same species cost slightly more each time, while plants and decor are one-time purchases.
- Invest in Upgrades: Buy upgrades to boost your income multiplier, extend your offline reserve time, and increase the frequency of random events.
