Reef Genesis

Start with one small tank and two fish. Feed them, grow them, breed them —

and find out what comes out of the egg.

Reef Genesis is a calm idle aquarium game about breeding and discovery.

Your reef keeps earning while your phone is in your pocket.

BREED AND DISCOVER

Cross two species and you might get something neither parent was. There are

56 species and 51 hidden crossbreeding recipes waiting to be found. The

collection book shows the silhouette of everything you haven't discovered

yet, and hints which pairs you have never tried.

NINE RARITY TIERS

Common, Uncommon, Rare, Epic, Legendary, Mythic, Ancient, Divine, Celestial.

Rarity is never for sale. Merge two fish of the same rarity to reach the next

one. The only way to a Celestial fish is the work you put in.

DECORATE YOUR OWN TANK

Rock, seaweed, coral, shell, anemone, amphora, shipwreck and crystal. Drag

them where you want, flip them, remove them if you change your mind. Indoor

aquariums slowly get dirty; wipe the glass and your income comes back up.

SIX GENES TO RESEARCH

Fast Growth, Golden Scales, Glowing Fin, Giant, Twin Spawn, Fertile. Genes

pass to offspring and show on the fish. The DNA Lab unlocks a gene so it can

appear; breeding does the rest.

FROM A HOME TANK TO THE DEEP OCEAN

Home Tank, Grand Aquarium, Reef Pool, Open Sea, Ocean and Deep Ocean: six

habitats, each with its own water, light, decor and species. Every one you

open adds slots. A prestige resets your coins and your fish, but the

habitats you opened stay yours.

REEF LEVEL

Everything you do earns levels: buying, breeding, finding a new species,

placing decor, feeding. Levels unlock decor, the lab, the market and the

arena; a pearl every five, a tank slot every ten.

A REEF, NOT A WAREHOUSE

Every different species in your tank raises your income. Sixteen copies of

the same fish earn less than sixteen different ones. Variety pays.

EARNS WHILE YOU SLEEP

Come back to hours of collected income. Three food tiers decide when you return:

crumbs for half an hour, kelp paste for four hours and 25% more income,

rich food for twelve hours and 50%. A visitor drops by once a day; missing one

costs you nothing.

FISH DO NOT DIE

A hungry fish stops earning and stops growing. That is all. You will never

lose a fish for being away too long.

THREE CURRENCIES, THREE SEPARATE JOBS

Coins buy fish, tanks and decor. Pearls come only from prestige and level

milestones, and are the key to rarity — never for sale. Gems buy time: skip

a timer, hatch an egg, grab the long food.

Gems can never buy rarity. That is not a slogan, it is a rule in the code.

FAIR BY DESIGN

- Rewarded ads are always optional and always pay out

- No forced ads, no pop-ups you cannot close

- Nothing you buy raises your rarity odds

- Miss a day of your streak and you step back one day, you do not start over

YOUR REEF SURVIVES A NEW PHONE

Start as a guest right away, no account needed. Turn on backup whenever you

like: sign in with Google, or write down the code we give you. Even when you

sign in with Google, we never ask for your name or your email.

FRIENDS, MARKET, CHAT

Share your friend code and others can look at your tank — looking is all

they can do. Buy and sell grown fish on the market, up to Rare: the rarest

fish stay something you breed, never something you buy. Chat in the public

room or privately with friends; reporting and blocking sit on every message,

and you can ignore the whole thing.

ARENA: RACES AND A REEF RUN

Enter a grown fish in a friendly race against another reef. Nothing is ever

lost and last place still scores. Each week the season closes and your points

pay out as Bronze, Silver or Gold. There is also the Reef Run, a short

obstacle dash you play yourself.

Landscape. English and Turkish. Plays offline apart from backup, market

and chat.
