Have you ever felt like there’s more to Mr. Mine than meets the eye? If so, you’re not wrong. The hidden areas in Mr. Mine are one of the most overlooked yet rewarding parts of the game. These secret places are tucked away below the surface, waiting for curious players to discover them.
From special NPCs hidden in caves to secret rooms filled with valuable relics, there’s a whole world beneath the mineshaft that many players never find. In this guide, we’ll show you how to spot these areas, why they matter, and what you can earn by uncovering them. Whether you’re just starting out or already deep in the game, there’s something here for every miner.
What Are Hidden Areas in Mr. Mine?
Let’s start with the basics. In Mr. Mine, you spend most of your time drilling down into the earth, collecting resources, upgrading your gear, and managing workers. But beyond the standard gameplay, there are hidden areas in Mr. Mine that are not part of the regular mining path.
These hidden spots can include:
- Secret caves that appear at specific depths
- Unique NPCs who give quests or drop rare items
- Random events triggered by certain actions
- Easter eggs that lead to achievements
So why should you care about finding them? These areas often hold some of the best rewards in the game. You might find powerful relics, unlock new features, or progress through a hidden storyline. If you’re aiming for 100% completion or chasing mr mine secret achievements, you’ll need to explore these spots.

The game’s developer, Playsaurus, has layered in plenty of surprises, encouraging players to dig deeper, revisit old locations, and explore every corner. With over a thousand kilometers of content to dig through, it’s easy to miss something if you don’t know where to look.
How to Unlock and Discover Hidden Areas
Early Game Hidden Spots
During the early part of the game, your main focus is digging, upgrading your drill, and managing your team. But even at this stage, hidden spots start to appear.
At depths of around 10 to 100 km, caves begin to show up. Many players click through them quickly, looking for treasure chests. But some caves have small secrets, like:

- Slightly different backgrounds that can be clicked
- Invisible objects that reveal a reward when you hover over them
- NPCs that show up once a quest is triggered
Keep an eye out for anything that looks unusual. Sometimes, a small detail in the environment can lead to a big discovery. Also, don’t forget to check in with the mr mine community. Many players share screenshots or notes when they find something new, and it’s a great way to stay up to date with the game’s secrets.
Mid-Game Secrets
As you reach depths between 100 km and 600 km, the game introduces more complexity. This is when the first major hidden areas begin to reveal themselves.
The Broken Robot (~225 km)

One of the most famous mid-game secrets is the Broken Robot. Found in a random cave at around 225 kilometers, this NPC doesn’t say much at first. But if you interact with him a few times and complete certain quests, he’ll eventually respond.
This robot becomes more than just an Easter egg. He leads you to new relics, triggers one of the mr mine secret achievements, and hints at deeper secrets in the game. Some players report that he gives items needed to unlock other hidden areas later on.
There are also mid-game caves that randomly generate secret rooms. These areas might contain:
- Rare chests with high-value upgrades
- Clues to where the mr mine orange fish is hiding
- Visual Easter eggs or nods to other clicker games
It’s during this phase that you should slow down and explore more. Use your mouse to hover over everything, click walls, and re-enter caves to see if anything changes.
Deep Hidden Encounters
Once you pass 600 kilometers, things start getting strange. You’re moving out of the regular Earth layers and into mysterious biomes. This is when hidden areas in Mr. Mine become more surreal.
Rare Characters
At these depths, new characters may show up randomly. One example is a character known as “Mr. Mime.” While it’s not officially confirmed by Playsaurus, the community has reported strange encounters with a figure that looks like a mime. Sometimes, talking to him rewards you with a relic or clue.
Another key figure is Jeb. He only appears in certain cave layouts and often after completing earlier quests. Jeb doesn’t always give a direct reward, but talking to him can trigger future events or lead to one of the mr mine secret achievements.
UFO and Space Secrets
After breaking through the Earth’s core, you enter space. And here, hidden content reaches a whole new level.
There’s a well-known rumor about a UFO that appears at a specific range of depths in the space biome. To trigger this, players need to:
- Reach a high depth (1,000 km+)
- Complete certain relic combinations
- Revisit space after building specific upgrades

Once the UFO appears, interacting with it may give you a unique item or achievement. Some say it also leads to a hidden storyline. Either way, it’s one of the more exciting Easter eggs in the game.
Orange Fish Mystery
Let’s talk about the most famous mystery of all — the orange fish Mr Mine fans keep chasing. Players across the Mr Mine Wiki, Reddit, and YouTube have tried to answer the question: Where is the orange fish in Mr. Mine?
There are several theories:
- It appears only after talking to specific NPCs
- It’s tied to the broken robot storyline
- It exists as a random event at extremely deep levels
While no one has confirmed a consistent method to find it, many players claim to have seen it deep in space caves. Clicking on the orange fish can give you a cosmetic bonus or relic, and it’s likely tied to one of the game’s secret achievements.
Hidden Achievements and Easter Eggs
Achievements in Mr. Mine aren’t just handed out. Many require you to think outside the box or find obscure triggers in the game. This is where hidden areas come into play.
Some examples include:
- Secret Laboratory: Only unlocked after completing a long quest chain and finding a hidden key in a deep cave.
- The Whisperer: An NPC who reportedly appears only if you’ve interacted with three specific items spread across different depths.
- Background Interactions: Clicking on objects in certain caves (like statues or broken machines) can trigger dialogue or mini-events that award achievements.
Easter eggs also appear in fun ways:
- References to other incremental games
- Messages from Playsaurus hidden in relics or upgrades
- Fake-out quests that seem like jokes but lead to real rewards
You’ll find that the more time you spend exploring, the more the game rewards you for being curious.
Best Tips for Uncovering All Hidden Content
Finding every hidden area in Mr. Mine takes time, but there are several ways to improve your chances.
Pay Attention to Depth Milestones
The game doesn’t tell you directly, but reaching certain depths triggers major content unlocks. For example:
- At 250 km, the robot appears
- Around 500 km, rare caves with unique relics start to show up
- 1000 km+ is where you’ll encounter space events like the UFO
Use your upgrade strategy to pace yourself at these levels. Don’t rush through with only drill upgrades. Instead, stop, explore, and interact with each new cave.
Let Quests and Achievements Guide You

Quests aren’t just filler. Many are designed to point you toward hidden content.
If a quest tells you to “observe the stars,” it might be a clue about the UFO. A task that mentions “lost memory” might connect to the broken robot. By following these breadcrumbs, you’ll be led to areas you might’ve missed.
Achievements also give hints. Even ones you haven’t unlocked will often show vague names or clues. Use those names to search the Mr Mine Wiki or join the mr mine community to compare notes.
Hidden Areas That Reward You the Most
While all hidden spots in Mr. Mine offer a sense of discovery, some deliver much more value in terms of gameplay. These are the hidden areas you’ll want to prioritize if you’re after powerful boosts, fast progression, or rare collectibles.
Golden Chest Caves

These caves appear randomly and are easy to overlook if you’re clicking too quickly. Inside, you’ll find:
- High-value relics
- Multiple chests in a single room
- Special upgrades not available through normal shops
To improve your chances of finding them:
- Slow down at milestone depths (250 km, 500 km, 1000 km, 1500 km)
- Revisit older caves after major drill upgrades
- Always check the environment carefully before leaving
The Orange Fish Encounter
Let’s revisit one of the game’s biggest mysteries. The orange fish Mr Mine moment is more than just a quirky Easter egg — it actually gives in-game benefits.
When you find and click on it:
- You’re rewarded with rare resources
- You unlock one of the hidden achievements
- Some players report gaining passive relic bonuses after this event
So, where is the orange fish in Mr. Mine? Based on community tips:
- It’s likely found between 1200–1600 km, often in space biome caves
- It may only appear after talking to the Broken Robot or Jeb
- You might need to have specific relics equipped for it to appear
If you see a faint shimmer or small movement in a cave, slow down and examine it. The fish doesn’t stay visible long, so be quick.
The Secret Lab
This is one of the most valuable hidden areas in the game. Players who access the Secret Lab often report major advantages in:
- Drill efficiency
- Resource generation
- Auto-upgrades

To unlock the lab:
- Find three hidden items across separate depths (usually tied to quests)
- Trigger a sequence by talking to specific NPCs
- Revisit a cave at 850 km once all conditions are met
This is a great example of how game strategy and exploration pay off in Mr. Mine.
Common Mistakes Players Make (And How to Avoid Them)
If you’re not uncovering hidden areas regularly, you might be falling into some of the most common traps. Here’s what to avoid.
Rushing Through the Depths
Many players, especially fans of clicker games, get into a rhythm: drill, upgrade, repeat. But Mr. Mine rewards exploration. If you move too quickly, you’ll miss:
- Timed cave spawns
- Random NPC events
- Quests that only activate at specific depths
Instead, pause after each major drill upgrade. Explore new cave layouts, and don’t assume everything worth seeing is at the bottom.
Ignoring Cave Interactions
It’s easy to think that if a cave has no chest, there’s nothing to do. But many hidden areas don’t look important at first glance. Be sure to:

- Hover over the entire screen
- Click every visual element (crates, rocks, signs)
- Revisit caves after completing side quests
A cave that was empty before might hold something new after you complete certain steps.
Skipping NPC Dialogue

Characters like the Broken Robot, Jeb, and even minor miners often drop clues. Their dialogue might seem like flavor text, but it can lead you to:
- Unlockable relics
- Hidden progression chains
- Triggers for major hidden areas
If you’re trying to complete all mr mine secret achievements, reading everything is a must.
Advanced Hidden Secrets and Theories
Thanks to an active mr mine community, players constantly share new discoveries, data-mined secrets, and in-depth guides. Here are a few of the most intriguing community-based findings and theories.
Mirror Mines Theory
Some believe there’s a second version of the mineshaft — a mirrored version where previously visited caves are altered or reversed. The idea is that:
- It becomes available after reaching 10,000 km
- You need a set of relics to open a portal in a specific cave
- Clues to its existence are hidden in rare achievement text
So far, it remains a theory, but many long-time players are investigating it seriously.
The Whisperer
A rumored NPC known only as “The Whisperer” is said to appear after completing the full robot quest line and reaching 5000 km. Descriptions include:
- A shadowy figure that speaks in single words
- Unlocks access to a hidden crafting system
- Connected to new relic combinations
While this hasn’t been confirmed by Playsaurus, several streamers and players on the Mr Mine Wiki have reported seeing something similar.
Relic Fusion
Another community theory suggests that some relics can be fused if equipped in the right order. This theory has some support from relic descriptions that seem to “complete” each other when read together.
Possible fused relics may unlock:

- A permanent boost to resource rates
- Access to ultra-deep caves
- Rare achievements or boss fights
The best way to stay updated on these is by following the mr mine community channels, especially Reddit and Discord.
Final Thoughts: Why Hidden Areas Matter
Let’s bring it all together. The hidden areas in Mr. Mine are more than just fun surprises. They’re key to:
- Unlocking the deepest layers of content
- Completing quests and earning secret achievements
- Gaining major gameplay advantages
- Experiencing the full creative vision of the developers at Playsaurus
Many players finish the main layers of mining without ever touching these secrets. That’s a shame, because these areas hold some of the best moments the game has to offer.
Whether you’re looking for the elusive orange fish Mr Mine has become known for, chasing down the Broken Robot’s questline, or trying to trigger a UFO event, there’s always something hidden just below the surface.
So, next time you drill, slow down. Click around. Talk to everyone. You never know what you’ll find — and that’s what makes Mr. Mine one of the most rewarding idle mining games out there.
