Mines are a definable shape and action that the player can set for the Bricktrons to do in Sandbox Mode. The player is given controls to expand the size of the mine while the task is selected. When setting up a mine, Bricktrons will start to dig and collect stone from the rocks and dirt they break. As they go down a lower elevation, they leave stairs that go around the perimeter of the mine so that they can climb back out.
Once Bricktrons get a full bag, they go back and put it into the stockpiles or barrels, which may hold rocks, stones, orange crystals, blue crystals, and wood. If no containers are set to hold any blue crystals, the Bricktrons will feed the large crystal with the blue crystals.
