Feature Overview
As your lumber empire expands from a tiny backyard operation into a global, multi-trillion-dollar automated enterprise, your profit margins will skyrocket. Standard numerical text scales poorly on mobile screens once your income reaches massive thresholds. To prevent dense walls of zeroes from cluttering your interface, Lumber Inc utilizes a streamlined Abbreviated Currency Notation System. This formatting standard makes massive balances immediately recognizable, easily scannable, and clean to compare at a glance.
How to Access
This notation system applies globally to every financial indicator across your facility. You can observe these abbreviations on your Main Cash Counter (top bar), your Machine Upgrade Buttons, your Workshop Blueprints, and your Order Board Contracts.
Core Mechanics
The game alternates from standard mathematical formatting to a hybrid text-and-alphabetical scale once numbers climb past one thousand. The financial scaling breaks down according to the following progression hierarchy:
Standard Industrial Tier
K = $1,000$ (One Thousand) — e.g., $15\text{K} = 15,000$
M = $1,000,000$ (One Million) — e.g., $3.5\text{M} = 3,500,000$
B = $1,000,000,000$ (One Billion) — e.g., $100\text{B} = 100,000,000,000$
T = $1,000,000,000,000$ (One Trillion) — e.g., $1.2\text{T} = 1,200,000,000,000$
Double-Letter Tycoon Tier
Once your earnings climb past one quadrillion ($1,000,000,000,000,000$), the standard naming conventions become too long for the game layout. At this point, the game engine shifts to a double-letter alphabetical rotation system:
aa = $1,000,000,000,000,000$ (One Quadrillion)
ab = $1,000,000,000,000,000,000$ (One Quintillion)
ac = One Sextillion (and so on, advancing sequentially through the alphabet)
Tips and Strategies
Mind the Alphabetical Gap: When planning upgrades, always look closely at the lettering, not just the base number. A machine upgrade that costs 1.0 ab is significantly more expensive than one costing 999.0 aa. Even though the digits look smaller, the single alphabetical letter step indicates a $1,000\times$ increase in value!
Track Your Multipliers: If you are trying to reach the next alphabetical tier (for example, jumping from aa to ab), focus on unlocking high-level sawmill managers. Their massive income multipliers are specifically designed to help your budget bridge these immense exponential gaps.
