The best upgrade is the cheapest current change that removes the measured bottleneck. Fix route mistakes first, choose treadmill upgrades for a visible Speed target, choose base upgrades for a confirmed base limitation, and compare money cost with time saved.
Upgrade by bottleneck
| Current problem | Check first | Likely path |
|---|---|---|
| Eggs rarely reach the base | Route, controls, rivals, and visible guards | Practice before spending |
| Visible Speed target is far away | Measured treadmill gain per minute | Compare treadmill upgrade |
| Base UI shows a capacity/workflow limit | Exact next base effect | Compare base upgrade |
| Money is the bottleneck | Pet lineup and observed income | Improve income before a costly upgrade |
| Egg growth blocks hatching | Current growth time and pass coverage | Evaluate Growth Speed separately |

Estimate payback without fake precision
For an upgrade that directly increases a measured rate:
- Extra rate = new measured rate − old measured rate.
- Payback time = upgrade cost ÷ extra rate.
- Use the same units and exclude temporary boosts unless they remain active.
If an upgrade improves capacity, protection, layout, or another non-income mechanic, do not force it into an income formula. Measure the task it actually changes.
Avoid these upgrade mistakes
- Buying several levels before measuring the first one.
- Using old prices or requirements from another universe.
- Treating X2 Growth Speed as treadmill Speed.
- Assuming a base upgrade must increase income.
- Saving for a large target while ignoring a cheap change with a short measured payback.
Upgrade priority FAQ
What should I upgrade first in Steal An Egg?
Fix the measured bottleneck. Improve route execution before spending, use treadmill upgrades for a visible Speed target, and use base upgrades only when their current displayed effect solves a base workflow or capacity problem.
Is the treadmill better than the base?
Neither is universally better. The official description confirms both can be upgraded, but current costs and effects must be compared in the live server.
Should I save money or buy a small upgrade?
Compare the time saved by the small upgrade with the delay it adds to the larger target. Measure before and after instead of relying on a universal level order.
