How it plays

You stand above the surface. Tap Cast line and the hook drops. From there the run plays out in two phases:

Descent. The hook falls toward the seabed 100 ft below. Fish swim across your path. Each time the hook bumps a fish (or a column wall) it's stunned for a beat — descent slows to a crawl. A descent timer caps the phase, so if you bump too many fish you don't reach the bottom and your catch ceiling shrinks.
Retract. Whether or not you made it all the way down, the line starts rising. New fish swim through the rising hook. The first ten fish you touch are caught. After ten, additional touches are ignored — choose carefully.

Scoring

Each fish has a base point value (small = less, large or rare = more). Your run score is:

score = round(sum(catch.base_pts) × clamp(depth_reached_ft / 100, 0.3, 1.5))

Cast deep and catch heavy. A shallow run with mediocre catches is worth a fraction; a max-depth run with the right ten is worth 1.5× the catalog sum.

The fish

178 catchables across eight families — freshwater, ocean, tropical reef, sharks & rays, deep sea, crustaceans & shellfish, mythic creatures, and sunken trinkets (yes, you can hook an old boot — or a cursed pearl). Every species has a weight, a spawn rarity, a point value (1 to 2,000), and a depth band scaled to your line length.

Catches are graded by rarity tier:

Tier	Feel	Examples
Common	every cast	Minnow, Sardine, Crab, Bluegill
Uncommon	regular	Trout, Cod, Salmon, Seahorse
Rare	a good run	Mahi-Mahi, Swordfish, Manta Ray, Piranha
Epic	worth bragging	Oarfish, Goblin Shark, Coelacanth, Whale Shark
Legendary	an event	Leviathan, Sea Serpent, Golden Fish, Baby Kraken

Deeper water holds rarer fish — commons thin out as you sink, and the legendary dwellers only appear in the bottom tenth of a deep cast at high line levels.

Logging & anti-cheat

Every interaction — fish spawn, hit, near-miss, catch, phase change — is timestamped and posted with the run. The server keeps the full event log forever (per the platform policy) and uses the same Mulberry32 PRNG the client uses, so submissions can be re-simulated and scored independently in the future.
