Bring a little aquarium to life, one fish at a time.
Your fish swim freely and produce treasures every five seconds. Tap a falling shell or swipe across a pile to collect it. Each fish tier has its own colors, accessories, and treasure shape.
Exchange your collected shells with the fisher for pearls. Check the current offer before exchanging. The pearl seller sells them over time, and your coins wait for you to collect them.
Buy more fish with coins, then merge three fish of the same tier. Discover up to 24 tiers, view each discovered fish in 3D, and find giant clams with fish inside. Each clam shows its possible rewards and their odds before opening.
• Portrait play with taps and swipes
• A hands-on first-play tutorial
• English and Korean, following your device language or your saved choice
• Automatic saves on this device and recovery from a valid local backup
• Up to eight hours of offline progress, within the floor's storage limit
Optional gem purchases can upgrade pearl sales speed and unlock permanent gold multipliers. Normal fish purchases use coins. Gems have no cash value and cannot leave the game.
Progress and gems are stored on this device. Cloud saves and cross-device gem restoration are not supported. Please contact support before deleting the app if you have a save or purchase issue.
