Flatten The Mountain Cash & Gems Guide

Version warning

The official Roblox description confirms that mining blocks earns Cash. The ore values, power-ups, and currency behavior below were documented on September 1–2. Roblox's public experience record changed on September 3, so every exact value is a dated observation.

Dated ore payout table

Coal was mentioned as an early material, but the source did not provide a precise payout that should be copied into this table.

The practical Cash route

1. Start automation early

Use the Beginner Guide opening: the September 2 route bought Damage I first, then Drone I, followed by Player improvements and Turret I. Saving all Cash while doing every block manually delays the system that earns while you move.

2. Aim your pickaxe at high-value ore

When an ore block appears, prioritize it with manual swings while automated workers continue clearing ordinary blocks. This is an editorial recommendation based on the large payout differences in the dated table; it is not an official “best route.”

3. Keep the layer clean

Do not chase a distant ore block if it leaves scattered blocks that prevent the current layer from clearing. Finish nearby high-value ore, then sweep the remaining surface so the layer counter advances.

4. Spend before the next bottleneck stalls you

Cash is useful only when it changes the pace of the current run. Buy a worker or a meaningful Damage/Mine Speed step instead of waiting through several slow layers for an upgrade that is still far away.

5. Use the Calculator for the current build

Historical ore values cannot tell you your current Cash per minute. Enter the Cash earned and active mining time from your current run in the Progress & Cash Calculator, especially after the September 3 record change.

Power-ups shown in dated material

2X Money

A September 1–2 guide shows a temporary 2X Money power-up. When it is active, spend the window mining the highest-value visible blocks instead of opening menus or crossing an empty section.

Mining Speed x1.5

The same dated source shows a Mining Speed x1.5 boost. Use the faster window on a dense layer where continuous swings or Auto Mine can stay on target.

The current duration, spawn rule, stacking behavior, and exact post-update effect were not confirmed.

Cash and Gems are different economies

A September 2 guide described Cash as an in-run currency and Gems as carrying into the lobby. Because persistence after leaving or changing servers was not independently confirmed, this page does not extend that statement into a universal save guarantee.

Dated Gem sources

• A chest result of 50 Gems appears in two public records.
• One full-clear record showed 400 Gems on a first run.
• A later Storm Hammer run in the same guide showed 500 Gems.

These are outcomes from specific recorded runs. They do not prove fixed chest or completion rewards.

A clean rate comparison

After using the direct route above, measure the version you are actually playing:

1. Record starting Cash.
2. Mine one uninterrupted section for a fixed time.
3. Do not purchase an upgrade during the sample.
4. Exclude time spent in menus or avoiding the eagle.
5. Divide Cash earned by active minutes.
6. Repeat after changing one upgrade.

The Calculator reports the measured rate and payback; it does not contain a hidden universal game rate.

Farming mistakes to avoid

• Counting a chest's Gems as ordinary Cash income.
• Comparing an ore-heavy layer with a stone-heavy layer as if the upgrade were the only difference.
• Spending most of a 2X Money window inside the Skill Tree menu.
• Assuming an old payout is current after the September 3 timestamp.
• Following a “best farming location” that does not account for the mountain changing as layers disappear.
