As your mines expand and your forge reaches higher levels, the amount of Gold you earn becomes so massive that standard numbers would completely block your screen! To keep the interface clean and easy to read, the game uses an alphabetical shorthand system to represent these giant values.
Currency Notation Guide
Here is a simple breakdown of how the notation scales up:
| Notation | Numeric Value | Name |
| K | 1,000 | One Thousand |
| M | 1,000,000 | One Million |
| B | 1,000,000,000 | One Billion |
| T | 1,000,000,000,000 | One Trillion |
| AA | 1,000,000,000,000,000 | One Quadrillion |
| AB | 1,000,000,000,000,000 | One Quintillion |
How the System Continues
Once you surpass AB, the alphabet simply keeps moving forward: AC, AD, AE, and so on.
After AZ: Once the sequence reaches AZ, the first letter steps forward to B, transitioning into BA, BB, BC, etc.
Why we use this: This system lets you effortlessly compare costs and upgrades at a glance. For example, if a shaft upgrade costs 10 AB and you only have 5 AA, you instantly know you need to keep saving!
