Private Mines are essentially a miniature version of the Home World mine that is in a separate zone. The surface size is quite small (3x3 blocks). However, it widens at 10 blocks deep (when you pass the black wall).
Private Mines are not only usable by the owner, but also by the owner's Roblox friends. They are commonly used to avoid harassment from other players (known as griefing or trolling).
The Private Mine is very utilitarian in design. It has red clay-colored walls, a shop, a sell area, and the mine itself.
To access Private Mines, walk into the teleport circle by the NPC, Mr. Miner. He is located between the beach teleporter and the Sell area. If you own the gamepass, you will be teleported to your mine. You are also able to teleport into your friends' mines. Note that the "Friends Mines" list will display any friends you have in the server, even if they do not own a Private Mine.
- There have been instances where players were able to access Private Mines through game glitches/bugs.
- When the mine collapses, players in a Private Mine will be teleported to the Main World's surface rather than the surface of the Private Mine.
- Only accessible through Earth.
