Shred the Secrets — How to Get Money Fast

1. Understand Where Money Comes From

There is exactly one income source: shredded documents. That means your cash per minute is a simple product of three things:

• 1Documents per trip — capped by your Document Carrying upgrades.
• 2Trips per minute — driven by Movement Speed and how short your route is.
• 3Time lost per pickup and dump — cut down by Vacuum and Shredding upgrades.

Every farming decision below optimizes one of these three numbers.

2. The Money Upgrade Order

Community guides consistently converge on the same spending order for pure income:

1. Document Carrying — the single biggest income multiplier. More papers per trip means every other stat works harder.
2. Movement Speed — compounds with everything; faster loops, faster secret hunting, faster badge runs.
3. Vacuum — wider suction and faster pickup turns room-clearing nearly hands-free.
4. Shredding — buy once large capacity loads start queuing at the machine, not before.
5. Progression — unlocks deeper rooms and story gates; buy when you are ready to advance.

Full tier ratings for all five upgrade lines are on the Upgrade Tier List.

3. Build the Best Farming Route

• Anchor on the shredder. Your route starts and ends at the machine — farm the densest rooms closest to it first.
• Fill before you return. A trip below full carry capacity is wasted upgrade money. Sweep with the vacuum until you are maxed, then dump.
• Expand only when it pays. Deeper rooms hold more documents, but the longer walk only wins once your capacity and speed make the round trip worth it.
• Chain secrets into the loop. Keys, hidden interactions, and unusual events sit along your farming path — grab them in passing instead of making dedicated trips.

4. Common Money Mistakes

• Buying Shredding too early — the machine is rarely your bottleneck before mid-game.
• Spreading cash across all five lines — focused Carrying + Movement investment out-earns balanced spending.
• Half-full trips — returning early throws away the value of every capacity upgrade you own.
• Hunting fake codes — there are no active codes, so time spent chasing them is time not spent shredding. Track real code news on the Codes page.
