Achievements
Collect all 38 Steam achievements in Hole Is Mine. Full guide for 100% completion, depth milestones and hidden unlocks like The Great Oh.
Introduction
Hole Is Mine ships with 38 Steam achievements, and they give completionists a clear set of goals to chase. The most visible are the depth milestones — Deep, Deeper, Deepest and Hyper Deepest — which track your descent through the Hole, but the list also includes hidden unlocks like The Great Oh whose conditions are not shown in-game. A handful of players have reported achievements not unlocking, so this hub also covers workarounds for stuck achievements. Whether you are aiming for 100% completion or just want to know what the milestones are, this guide to all 38 achievements will help you plan your run.

Core Mechanics
Achievements in Hole Is Mine mostly track your progression through the game's systems. The depth milestones — Deep, Deeper, Deepest and Hyper Deepest — unlock as you descend through the Depths, giving you concrete markers of your journey. Other achievements are tied to the game's content: collecting Mini'Ohs, building equipment combos, growing the Village and finding secrets. A few are hidden, most notably The Great Oh, which does not show its unlock condition and has become the game's biggest community mystery. There is also a reported bug where some achievements do not unlock when their conditions are met — players on the Steam community have shared workarounds, and the developers may address it in a patch. The fastest path to 100% is to play naturally through the Depths, then mop up the collectible and secret achievements in the post-game.
Advantages
The achievement list gives Hole Is Mine a clear completionist goal that fits the game's loop beautifully. Most achievements unlock through natural play — descending the Depths and using the game's systems — so you collect most of them just by enjoying the game, and the rest are reachable with a little focused work. The hidden achievements add spice, because mysteries like The Great Oh give experienced players something to hunt beyond the plain checklist and keep the community talking between patches. The depth milestone names, Deep, Deeper, Deepest and Hyper Deepest, are also a genuinely funny escalation that fits the game's whimsical tone, and the total of 38 achievements is a satisfying number for completionists to work toward.
Challenges
The achievement system has real rough edges at launch. Several players have reported achievements not unlocking even when they clearly meet the condition, which can be deeply frustrating for completionists, and the workarounds are not officially documented anywhere. Hidden achievements like The Great Oh are so opaque that they may require outside research to find, which not every player enjoys. Finally, because the game is brand new, the community has not confirmed every achievement's exact condition yet, so parts of this guide are based on the best available reports rather than verified data. If you hit a stuck achievement, patience and the community forums are the best tools you have.

Quick Tips
Play through the Depths naturally first, because the milestone achievements will come on their own. Chasing them early wastes time you could spend building a stronger mining base, and the same progress that unlocks achievements also unlocks the tools you need to earn the harder ones later. Play naturally and the milestones will arrive on their own, so focus your early sessions on building a strong mining base instead.
Keep a checklist of collectible achievements — Mini'Ohs, equipment combos and secrets — and mop them up in the post-game. By then you have the upgrades and tools to reach everything easily, and the checklist turns a daunting 38-item list into a simple to-do list you can finish in an evening.
If an achievement seems stuck, finish your current session, restart the game and retry the trigger. Several players report this clears the unlock bug, and the community forums have more workarounds if it persists. Keep an eye on patch notes too, because the developers may fix the root cause. Also check the Steam patch notes, because the developers may fix the underlying unlock bug in a future update.
