What happens when a Mini’oh runs out of power halfway down the shaft? In Hole is Mine, it just stops — sitting there, unreachable until you send a fresh one after it, and that small moment of loss is the first real lesson the game teaches about its whole economy.

The premise of Hole is Mine is stranger than most incremental games bother to be: you’re not mining directly, you’re dispatching small creatures called Mini’ohs down into the Hole to do it for you. Each launch sends one diving into the dark, and what it brings back depends on depth, equipment, and a bit of unpredictability in what the Hole actually contains at that layer.
Managing multiple Mini’ohs at once quickly becomes the real skill test. Early on it’s tempting to send every available Mini’oh down at the same depth for a steady, predictable trickle of resources, but players who instead stagger launches across different depths tend to find rarer materials faster, since deeper layers hold better rewards but also carry more risk of a Mini’oh getting stuck or running out of power before it resurfaces.
Raw materials pulled up from the Hole aren’t immediately useful — they need purifying first, which is its own resource sink layered on top of the extraction loop. This is where a lot of new players get their pacing wrong, dumping everything into more Mini’ohs or deeper launches without setting aside currency for purification upgrades, then wondering why their stockpile of impure materials just keeps growing without converting into anything spendable.
The Village sits on top of all this as the long-term goal: growing it requires a steady supply of purified resources, not raw ones, which forces players to treat purification as a priority rather than an afterthought once the early shallow-water grind stops paying off on its own.
Beyond raw extraction, Hole is Mine lets you customize individual Mini’ohs with abilities that change how they perform on a dive — some suited to speed, others to surviving deeper layers without burning through power as fast. Finding hidden secrets tucked into specific depths rewards players willing to experiment with these builds rather than running the same default Mini’oh loadout on every launch.
What players discuss most in the game’s community spaces is the Infinite Hole mode added after the initial prologue release, since it gives the demo actual long-term structure instead of ending abruptly once the main content is cleared — a common complaint about incremental demos in general, and one this update was a direct response to.
Hole is Mine works because the Hole itself stays a little mysterious even as you optimize around it — every Mini’oh sent down is a small bet, and watching one return loaded with something better than expected is still the moment the whole loop is built around.
