How do you measure offline earnings?
Record the time you leave, the time you return, the state before leaving and the state after returning. Then compare the change over the actual elapsed interval. The result describes your observation; it does not establish the game's internal formula or a universal rate.
The official icon advertises offline mutations, but the reviewed sources do not state a duration, a cap, a probability or a multiplier. A measurement can still be useful for your own planning if you keep the interval and the conditions attached.
Record one offline interval
Record the state before leaving
Copy the balance, the displayed rate, the pet label and any active boost. Note the exact time from a clock you will use again. A screenshot is useful, but the written fields are easier to compare.
Leave through the normal exit
Use the game's normal leave flow rather than closing a device abruptly. Record anything unusual, such as a server message or a disconnected session. An abnormal exit may change what the game records.
Return after a known interval
Note the return time and the state before interacting with anything. If a reward panel appears, copy its values before dismissing it. The first view is often the only record of what the game credited.
Compute the change, not a formula
Subtract the starting balance from the return balance and divide by the elapsed hours if you want an hourly figure. Label it as your observed change over that interval, not as the game's official rate.
Offline record sheet
| Target | Field | Illustrative example | Why it matters |
|---|---|---|---|
| Balance after | Balance after | 19,000 | The ending value |
| Balance before | Balance before | 10,000 | The starting value |
| Elapsed time | Elapsed time | 2.5 hours | The denominator for an hourly figure |
| Leave time | Leave time | 18:00 | Starts the interval |
| Observed change | Observed change | 9,000 over 2.5 h = 3,600/h | Arithmetic from the recorded values |
| Return time | Return time | 20:30 | Ends the interval |
What one return cannot prove
A single interval can be affected by a boost that expired, an event that started, a server change or a reward that was not purely offline. If you do not know the conditions, the hourly figure is a description of one interval, not a stable rate.
The game may also cap or modify offline earnings in a way the sources do not describe. A longer interval is not automatically a better test, because a cap would flatten the result. Record at least two intervals of different lengths before treating the number as a trend.
Why two intervals are better than one
A single interval cannot separate a rate from a cap, a one-off bonus or an expired boost. Two intervals of different lengths give you a second point of comparison. If the hourly figure falls sharply at the longer interval, a cap or a changing condition is a plausible explanation.
Keep the two intervals separate in the record. Do not average them into one number before checking their conditions. An average can hide the exact change that matters, especially when one interval included an event and the other did not.
Keep the calculation honest
- State the interval in hours and the exact timestamps.
- Record the starting and ending values before spending anything.
- Separate a boost or event from the offline change.
- Do not extrapolate beyond the longest interval you measured.
- Do not present one interval as the game's official rate.
- Keep failed or interrupted observations in the record.
Offline earnings questions
How much does Fake an Egg pay offline?
No official offline rate has been verified. The reviewed promotion does not state a rate, duration or cap. You can measure your own interval, but the result describes that interval rather than a universal value.
Does the offline timer keep running while the device is off?
The reviewed sources do not establish how the timer behaves across devices or closures. Record the timestamps and the exit method you used. Do not assume a closed device and a normal leave produce the same result.
Why did my second interval earn less per hour?
A cap, an expired boost or a changed event could all produce that result. Check the conditions before concluding that the rate changed. Two intervals with different conditions are not a controlled comparison.
