Hole Is Mine Wiki — Guides, Mini'Ohs, Upgrades & Secrets

You launch adorable Mini'Ohs into the divine Hole to mine impurities automatically. Extract those impurities to fuel upgrades, drill deeper with Shelly to unlock new Depths, and rebuild the Village as you go. The core loop is simple: launch, mine, extract, upgrade, descend.

Mini'Ohs are the small, round mining creatures you throw into the Hole. They mine impurities for you automatically, but they fall asleep over time and need to be relaunched. You can customize their colors and equip powers across 500+ equipment combinations.

Mini'Ohs get tired after mining for a while and fall asleep, which stops their production. Just pick them up and launch them back into the Hole to resume mining. Keeping several Mini'Ohs and cycling between them is one of the best early-game habits.

The Mending Crutch is an equipment tool that players frequently ask about on the Steam forums. It is part of the equipment system: equipping tools like it to your Mini'Ohs changes how they mine. Community reports suggest it boosts digging effectiveness, though the exact numbers are still being tested.

The Steam store page advertises roughly 40 Depths. The game is split into Caves — the playtest mentioned 5 Caves — and you clear the hazards in each one to unlock the next. After the final Depth you reach the Infinite Hole, a post-game farming area. The exact Cave-to-Depth mapping is not fully documented by the developers yet.

Most players complete the main journey through the 40 Depths in roughly 4 to 5 hours. 100% completion takes longer because hidden secrets, The Great Oh and all 38 Steam achievements require extra exploration and careful tracking.

The Village is your home base above the Hole. As you purify impurities and uncover secrets, you rebuild the Village and grow a community of Mini'Ohs. Investing resources into Village upgrades unlocks buildings and rewards that support your run.

Hole Is Mine has 38 Steam achievements. They include depth milestones such as Deep, Deeper, Deepest and Hyper Deepest, plus hidden unlocks like The Great Oh. A few players have reported achievements not unlocking, so check the community forums if one seems stuck.

At launch the game holds a Very Positive rating on Steam from around 80 reviews. Fans love the adorable Mini'Ohs, the satisfying launch-and-collect loop and the cozy incremental pacing. If you enjoy games like these and a $7.99 price point fits, it is an easy recommendation.

No active redemption codes have been found so far. The game does not appear to have a public code system at launch. If the developers add codes later, this wiki will list them as soon as they are verified.
