The official description states that shredding documents produces cash. It does not publish cash per stack, class bonuses, upgrade multipliers, or the best farm rate.
Improve cash flow
Cash efficiency comes from keeping the whole loop moving. Collect documents and vacuum scraps by zone, carry paper toward a usable shredder, finish the live shred interaction, and spend only when an upgrade removes a repeated delay. Measure a complete room rather than one unusually good stack.
Official cash goals
- Millionaire: collect $1,000,000.
- Cooking the Books: earn $10,000,000 across all runs.
The wording distinguishes a one-million collection target from a ten-million cumulative target. It does not say whether every source counts, whether teammate earnings share, or how the counters handle reconnects. Check the live badge progress and record the run conditions.
Avoid promising a per-minute rate unless it includes date, class, Skill Tree state, party size, room, and a repeatable sample. A route that leaves documents behind may look fast but works against the verified Secrets? What Secrets? objective to shred every last document in one run.
