In Circle Grinding Incremental on Roblox, you’ll work through several systems that multiplicatively boost one another through some very intense mathematics. Each system is finished once it’s completely automated, and so you move on to the next one – but there is one system that this rule doesn’t apply to: the cave system.

Roblox Is Under Investigation By The SEC For An Unknown Reason
The US Securities and Exchange Commission has confirmed that Roblox is part of an ongoing investigation.
The caves are used from very early in the game, and have content for each system after they’ve been unlocked, meaning it’s an ever-important space you should have your eyes on. It is a very complicated system, so this guide aims to answer your questions and guide you through everything they offer.
What Are The Caves?
The caves are a system you unlock when upgrading to Tier 2 – String. There are very few missions that are related to the caves, so, for the most part, the caves are completely optional – though, that isn’t to say that they should be ignored.
Your objective in the caves is to mine blocks and ores, and these can then be sold for coins. Each cave you unlock has upgrades you can unlock by either:
- Collecting a certain amount of coins, or
- Finding (and using) certain ores or blocks.
Each cave also has an index of ores, sorted by rarity. Once you find and break an ore, it’s unlocked in the index, and you gain a permanent +10 percent coin boost per ore. Ore rarities are the same for each cave, and each index usually has the same number of ores per rarity, as follows:
|
Rarity |
Per cave, ores of that rarity |
|---|---|
|
Common |
Four or five |
|
Uncommon |
Always three |
|
Rare |
Two or three |
|
Epic |
Two or three |
|
Legendary |
Two or three |
|
Mythic |
One, two or three |
|
??? |
One or two |
|
!!! |
Always one |
Every Cave In Order
To unlock each subsequent cave, you’ll need to unlock it elsewhere in the game first. This can be done in a couple of ways, but progressing through the main game always guarantees you’ll eventually unlock the next stage in the caves. Once unlocked, you’ll also need a Pickaxe Power level high enough to be able to break the blocks blocking the entrance to the next cave.
There are 12 caves in total.
First Cave, Dirt
This is the first cave you unlock, and the basic block here is Dirt. There are three upgrades:
