Quick Guide

  • The DIRT FOSSILS room unlocks at 2,000 Cash — the game’s collection layer.
  • Every dig costs 250 Cash and rolls for rarity against your Luck.
  • Shinies are the rare highlighted variants; Titles add another Luck-driven roll.
  • Luck sources stack: the active code (x1.2 permanent), Roblox Plus (+20%), and title bonuses.

How Fossil Digging Works

Fossils are Depth Incremental’s collection system and a long-term payoff for Cash. The DIRT FOSSILS room opens once you hold 2,000 Cash, and every dig inside costs 250 Cash. Each dig rolls for rarity — and the roll is weighted by your Luck stat, which is why Luck is the smartest stat to stack before a digging session.

The official description frames the loop as “Dig up Fossils and hunt rare Shinies ✨”: fossils feed your economy and upgrades, while the rare Shiny variants are the collector’s chase. The developer has not published an official rarity table or drop rates — this guide sticks to verified mechanics and marks the rest as unverified.
