One gem was hidden in every painted scene. Finding it was the whole game.

The game

One gem was hidden in every scene, painted the same colour as whatever it rested on — a roof tile, the water under a bridge, a lit window at the end of a street. Finding it was the whole game.

Nothing counted down. You could pinch to zoom, pan around, put the phone on the table and come back to it. Your time was tracked, but it never worked against you.

When you were stuck, a hint lit up the part of the scene the gem was in without pointing at it.

Players could also describe a scene of their own, have it generated with AI and share it with others. Every scene was checked by hand before it joined the rotation.

What was in it

Three levels of stubborn

Easy, medium and hard changed how closely the gem matched the paint behind it. Medium and hard unlocked as you levelled up, and harder finds were worth more.

Scenes painted to order

You typed a place or situation — an Egyptian alien pool party, Vikings sailing through the ocean at night — and our AI turned it into a scene in about a minute, with a gem hidden somewhere inside.

Gems, levels and streaks

Gems paid for hints. You earned them by finding gems, and free ones arrived every day, with more the longer you kept your streak alive. Health Gems refilled on their own while you were away.

Closed

Hidden Gem closed on 9 November 2026. It can no longer be downloaded, and the server it relied on has been shut down, so the game no longer works on iPhones that still have it installed.

Every player account was deleted together with the server: progress, balances, scenes and reports. We did not keep a copy.

The privacy policy and the terms of service stay on this site as a record of how the game worked while it ran.
