About Otter Deep Dive
Otter Deep Dive is a cozy idle fishing game starring a sea otter in a little red rowboat. Tap to cast and the hook sinks into the sea, past sunny reefs and kelp, down into the dark where glowing creatures live. How deep it goes depends on your Depth upgrade.
Every cast has two halves. On the way down you steer the hook between the fish, because the first one you touch turns it around. On the way up you do the opposite and steer into as many fish as you can hook. Back on the boat each fish turns into shells, and every new species fills a page of your collection book.
Shells buy three upgrades: Depth for more metres, Catch for more fish per cast, and Offline so your otter crew keeps fishing while you are away, for up to four hours. A Deep Dive potion sends one cast 50% deeper, and a treasure chest fills up as you play.
There are 21 species across four zones, from sardines and clownfish in the Sunlit zone to anglerfish, an octopus and a whale in the Abyss, plus a legendary golden fish. Progress saves automatically on your device, and soft ocean waves play in the background.
How to play Otter Deep Dive
- Tap to cast. The hook sinks from the otter's boat into the sea.
- On the way down, drag left and right to dodge the fish. The first fish you touch turns the hook around.
- On the way up, steer into fish to hook as many as your Catch level allows.
- Back on the boat you earn shells for every fish. New species go into your collection book.
- Spend shells on Depth, Catch and Offline upgrades, and try to find all 21 species across four ocean zones.

Tips and tricks
- Deeper means better fish: early on, put most shells into Depth.
- Buy Catch when your hook keeps filling up before it reaches the surface.
- Dodge by moving early into a gap; small, smooth moves work better than big swipes.
- Offline pays shells while you are away for up to four hours, so buy a few levels before a break.
- The Deep Dive potion sends the hook 50% deeper for one cast, which is the quickest way to meet a deeper zone's species.
- Rare species you have not caught yet show up more often, so keep casting at your deepest depth.
