Map the approach
- Mark the shortest and least visible approach paths
- Time travel from the boundary to the egg area
- Note where turns, obstacles or guards slow movement
- Retest after a base upgrade or patch
Three-scenario defense test
| Scenario | Measure | Weak result | Next action |
|---|---|---|---|
| Direct approach | Boundary-to-egg time and your reaction time | Attacker reaches the target before you can respond | Test visibility, positioning or one base upgrade |
| Hidden or turning route | First visible point and remaining travel time | You see the attacker only after the useful response window | Change observation position and retime |
| Busy-server distraction | Missed approaches during a fixed session | Defense fails while you train, hatch or leave the base | Reduce exposure or choose a lower-risk activity cycle |
Upgrade by measurable effect
Record income stability, reaction time and failed steals before and after one upgrade. Price alone cannot rank a base upgrade if the exact benefit is unknown.
Calculate the opportunity cost
Divide the displayed upgrade cost by your measured team income per second to estimate how long you must earn before buying it. Then compare the upgrade’s measured reduction in losses with that earning time. The base upgrade planner keeps the cost, session budget and reserve together; it does not invent the upgrade’s effect.
Keep a seven-session result log
| Field | Before upgrade | After upgrade |
|---|---|---|
| Sessions observed | At least 3 | At least 3 under comparable conditions |
| Approaches seen | Count | Count |
| Successful interceptions | Count and route | Count and route |
| Eggs or income lost | Record displayed loss | Record displayed loss |
| Patch / server context | Record | Keep comparable or flag the difference |
Balance defense and progression
Overinvesting in a benefit you have not measured can slow pet income and Speed training. Compare the next base purchase with the expected session gain from the income calculator.
Study both sides
The best defense tests the same routes an attacker would choose. Read the stealing guide and use the run planner to understand the opposing safety margin.
