A quiet idle game about digging a hole and never quite finishing it.
Your crew hammers away at the rock below. Every Chunk they break pays Gold, every Layer you clear takes you one Depth further down, and the rock gets harder the deeper you go.
Close the app and the crew keeps working. Come back to banked Gold and pick up where the hole left off. Fissure is built to be checked on rather than ground out — a few minutes at a time, several times a day, with nothing punishing you for leaving.
The rule that matters
A Digger too weak for the rock in front of it does not chip away slowly.
It deals exactly zero damage, and it says so — TOO WEAK, right there on the Digger.
So the hole stops when your crew outgrows its usefulness, and the only way down is to merge two matching Diggers into one stronger one. It is not an optimisation you can skip. It is the game.
Twelve slots, and a crew that keeps outgrowing them
A merge grid of twelve slots below, a pit above, and a Hardness gate that tells you exactly which of your Diggers is dead weight. Break a Surge Chunk and every Digger hits five times as hard for fifteen seconds.
Go back up to go deeper
When the hole goes quiet, you return to the top and start over — but never from nothing.
Every run pays out Geodes for how deep you got, and Geodes buy five permanent upgrades that no reset ever touches.
- TemperingHardens every pick, so your crew swings like a higher Tier and the Hardness gate moves out of your way.
- ImpactEvery strike hits harder.
- SpeedYour crew swings faster.
- Gold RushEvery Chunk pays more.
- Deep SleepThe mine banks more hours while you sleep.
The first run ends somewhere around Depth 40. The next one goes further, and so does the one after that. There is no last floor to reach.
