Coal Mine Maze: reach level 11, then rotate.

Miner Maze is currently the strongest community-reported repeatable TerraBucks grind, especially while every Coal mine still has its own separate game level.

15 TBReported easy reward, levels 1–10
30 TBReported medium reward from level 11
60 TBReported hard reward from level 31
01

The rotation

Farm the efficient early sequence on every Coal mine.

  1. Open your property list and filter for Coal mines.
  2. Select a Coal mine with a low Miner Maze game level.
  3. Clear levels 1 through 10 at the reported easy reward.
  4. Complete level 11 for the first reported medium reward.
  5. Move to another fresh Coal mine and repeat.

This works because mini-game progress belongs to each property. A new Coal mine does not inherit the harder level reached on a different mine.

Maze controls

Read the tunnels before tapping.

  • The exit is consistently located in the bottom-right area.
  • The first tap may turn the miner; the following tap moves in that direction.
  • Ladder tiles generally allow vertical movement, not horizontal movement.
  • Open tunnel tiles can be crossed when a solid wall does not block the route.
  • Increasing screen brightness may make walls and ladders easier to distinguish.

Avoid automation, image solvers that play for you, or tools that bypass cooldowns. TerraMine's terms prohibit bots and automated reward accumulation.

03

When not to rotate

Continue deeper when materials matter more than TB speed.

Higher mini-game levels can provide more upgrade materials and improve access to rarer drops. Rotating at level 11 is therefore a TB-per-time strategy—not a universal rule.

Plain-English answers

Frequently asked questions

Why stop at Coal level 11?

Level 11 is currently reported as the first medium-difficulty reward. Rotating then lets you repeat the easier early sequence on another Coal mine.

Are the Coal rewards officially guaranteed?

No. The exact 15/30/60 TB values are current community reports and can be changed by game balancing.

Does the 20× earnings boost multiply Miner Maze TB?

The official guide describes the boost for passive earnings and check-ins, not Miner Maze rewards. Treat boosting and the Coal rotation as separate systems.
