Mini'Ohs
Everything about Mini'Ohs, the adorable minions that mine the Hole. Learn how to get, care for, launch, customize and manage your Mini'Ohs.
Introduction
Mini'Ohs are the heart of Hole Is Mine — the small, round, utterly adorable mining creatures you throw into the divine Hole to do the digging for you. Every mechanic in the game orbits them: you launch them to mine, feed and care for them so they keep working, customize their colors and equipment, and watch them build a community in the Village. Players fall in love with these creatures immediately, and they are the most asked-about feature in the Steam reviews. This hub explains how to get Mini'Ohs, how launching works, why they fall asleep, how to care for them and how customization and the 500+ equipment combinations let you turn each Mini'Oh into your perfect helper.

Core Mechanics
Mini'Ohs work on a simple but surprisingly deep loop. You launch them into the Hole and they automatically mine impurities until they grow tired and fall asleep, at which point you pick them up and throw them back in to start again. Because each Mini'Oh has its own sleep cycle, managing a small crew of them becomes a light timing puzzle: keep a few awake while others rest and your mining never stops. Feeding and caring for Mini'Ohs improves their performance, and the customization system lets you change their colors and equip powers drawn from the 500+ equipment combinations. Different Mini'Ohs and loadouts suit different goals, so part of the strategy is building the right crew for the Depths you are pushing into.
Advantages
Mini'Ohs give Hole Is Mine its charm and its gameplay depth at the same time. The launch-and-collect loop is immediately satisfying — throwing a cute creature into a hole and watching it haul up treasure never gets old — and it is the reason so many reviews single the minions out. Underneath the cuteness there is a real system: the sleep mechanic forces you to plan your crew, care keeps you engaged with each Mini'Oh, and the 500+ equipment combinations give you a long tail of experimentation. Mini'Ohs scale with the whole game, so the crew you build in the first hour is still relevant at the deepest Depths.
Challenges
The main friction with Mini'Ohs is the sleep mechanic. Some players find relaunching them constantly more of a chore than a puzzle, especially in long idle sessions, and the Steam reviews show the mining mechanic is the most polarizing part of the game. Because the exact unlock conditions for rare Mini'Ohs are not fully documented, some of the information here is community-reported and marked as such. We also do not yet know the full list of every Mini'Oh variant, so treat the "all Mini'Ohs" sections as a growing list rather than a complete encyclopedia.

Quick Tips
Relaunch sleeping Mini'Ohs in batches rather than one at a time. A quick sweep around the Hole every few minutes keeps your whole crew working and is far less tedious than reacting to each one individually. Once you have several minions, a batch routine keeps production steady with minimal effort.
Invest early in anything that makes your Mini'Ohs work longer before sleeping. Every improvement to their awake time is a direct production boost, and because it applies to every minion in your crew, the benefit compounds across the whole game. Sleep management is the real skill of the early loop.
Do not neglect feeding and care. A well-cared-for Mini'Oh mines noticeably better and works longer, and the difference adds up across a crew of several minions. Tending your crew right after a relaunch round makes the care buff overlap with their full mining window for maximum output.
