To build tunnels in Dig on Roblox, you usually need to dig a clear path underground, then widen and support it so you can keep moving safely. The exact steps depend on which “Dig” game you mean, but the basic loop is: find a spot, start digging downward or into a wall, clear a long passage, and make sure you can get back out.

Simple tunnel method

  1. Pick a starting point in a hill, cave, or soft terrain.
  1. Dig straight in until you create a passage.
  1. Keep the tunnel wide enough to move through without getting stuck.
  1. Expand side rooms or branches only after the main path is stable.

If you mean Roblox Studio

If you mean building tunnels inside Roblox Studio , players commonly make them by cutting one part out of another or using basic shape tools to carve a passage. That lets you create clean tunnel entrances and curved interior spaces.

Practical tips

  • Start small, then expand.
  • Make the entrance obvious so you do not lose the tunnel.
  • In creative/building modes, use slopes or hollowed shapes for cleaner results.
  • If the game has a mining or drilling system, follow the tool’s upgrade path so digging becomes faster.

About the wording

“Robloxw” looks like a typo, so I answered for Dig Roblox and also for Roblox Studio tunnel building.

TL;DR: Dig a main passage first, keep it wide enough to walk through, and widen it later; if you meant Roblox Studio, tunnels are usually made by cutting or shaping parts rather than hand-digging.
