## What is Pocket Reef?

Pocket Reef is a cozy aquarium game about breeding fish and discovering what comes out.

Pair two fish and wait for the egg to hatch. Every fish carries a real genome — species, pattern, colour and face are inherited separately, so a pairing can surprise you. Thousands of distinct combinations exist, and the Aqua-dex tracks every one you have found, grouped by pattern so you can see exactly what is still missing.

Nothing in Pocket Reef punishes you. Fish never die. Timers finish while you are away, and a notification lets you know when an egg is ready. Put the game down for a week and your reef will be exactly as you left it.

WHAT YOU CAN DO

• Breed for traits — chase a specific colour or pattern, or pair at random and see what surfaces
• Fill the Aqua-dex — every combination is catalogued, with completion shown per group
• Complete the Order Board — neighbours request a fish by its traits each day. Hand one over for coins, with a streak bonus for keeping it up. A close match still pays, so there is always something you can fill
• Collect sets — colours, patterns, fins and faces each form a checklist with rewards
• Decorate your tanks — earn and place decorations, and choose a backdrop for each tank
• Play without an account — no sign-up, no login, and your reef is ready the moment you open the app

Pocket Reef is free to play. It includes optional ads and optional in-app purchases; neither is required to see everything in the game.

## Version history (last 3 releases)

### 1.1.1 — 2026-10-08

Small behind-the-scenes fixes.

### 1.1.0 — 2026-09-22

Turn your tablet sideways and the reef turns with it -- a proper wide tank, with the menu as a side panel next to your fish. Selling is paused during the intro, and if you're ever down to one fish, a hint takes you straight to ordering another. Fixed a bug where backing up with Google could quietly not happen if you took your time on the account picker. Plus the usual small fixes.

### 1.0 — 2026-09-11

No release notes.
