Coins/h comparison
Hourly efficiency monitor
Solo Shift 1 Short Loop (single Shift short loop)
- Risk rating
- LOW_ZERO_RISK
- Time cost
- 2 - 4 Mins per Run
- Recommended role
- Any / Default Starter
Shift 1 has 100% guarantee of ZERO anomalies. No penalty risks. Resetting after Shift 1 limits loss to 2 mins instead of wasting 12 mins on high-tier failure.
Shutter AFK Farm (Passive Shutter AFK route)
- Risk rating
- MEDIUM_PERK_LIMIT
- Time cost
- Passive Grinding
- Recommended role
- Head Nurse / Secretary
Requires purchasing extra check-in windows. Closing front shutters traps patient flow. Note: hard cap/threshold exists after 100 prevented anomalies.
Doctor Solo Progression
- Risk rating
- HIGH_ERR_MARGIN
- Time cost
- 15 - 25 Mins per Shift
- Recommended role
- Doctor (Bridge Role)
High stability due to Doctor's passive healing perk. Turns chaotic wild runs into steady solo progression, keeping high-tier multiplier active.
ROI model
Why repeated Shift 1 wins the coin race
If your goal is only to reach Surgeon as quickly as possible, restart after Shift 1 and keep the run inside the zero-anomaly window. The method trades long-run upside for clean repeatability, which is exactly what a coin unlock route needs.
Surgeon costs 2,500 Animal Coins. At the listed Shift 1 speed band, the terminal window is 19 to 33 hours when reset speed, loading, and run consistency are included.
Decision table
Choose the right farming lane
| Method | Coins/h | Risk | Best use |
|---|---|---|---|
| Solo Shift 1 Short Loop | 125 - 130 Coins/h | LOW_ZERO_RISK | Any / Default Starter |
| Shutter AFK Farm | 45 - 60 Coins/h | MEDIUM_PERK_LIMIT | Head Nurse / Secretary |
| Doctor Solo Progression | 75 - 110 Coins/h | HIGH_ERR_MARGIN | Doctor (Bridge Role) |
Execution rules
Fastest coin route protocol
- Use Solo Shift 1 Short Loop when the only goal is fastest Surgeon unlock progress.
- Use Shutter AFK Farm only when passive grinding matters more than maximum Coins/h.
- Use Doctor Solo Progression when you want a stable bridge route instead of short-loop resets.
- Do not keep a failing high-tier run alive when the time loss is already larger than a clean Shift 1 reset.
