Use the ten Update 8 upgrade levels and two Buy Tiers without inventing their costs or effects: record the current panels, diagnose the farm, and compare the visible payoff.
Update 8 officially adds ten upgrade levels and two Buy Tiers. The captured description does not name every level, cost, requirement, or effect. Read those fields in your current server and favor the displayed option that removes the measured production, processing, capacity, nest-slot, merge, or rebuild constraint.
Each step ends with a visible decision so you can stop, measure, or change course.
Open the current Gem Upgrade or Buy Tier panel and write down the exact name, cost, currency, requirement, and effect. Update 8 supplies the counts—ten upgrade levels and two Buy Tiers—but not a complete public table, so the game screen is the practical input for the decision.
Watch out: Do not assign an effect to a level because another guide uses a similar icon or name.
Use a stable one-minute measurement to compare egg production with processing and available capacity. Check active chickens against nest slots and review the remaining merge deficit. The best visible upgrade is the one that helps the current constraint, not automatically the most expensive or newest level.
Translate the displayed effect into a practical question: Will it shorten the current merge farm, stop capacity from filling, create needed nest room, or reduce rebuild time? If the effect cannot be connected to a measured result, save the resource until the benefit is clearer.
A Buy Tier can compete with chicken purchases, Gem Upgrades, or a Rebirth target for time and currency. Compare how long each option takes at the observed Cash rate and what current progress it preserves. The Rebirth helper can frame timing, but the game must provide the permanent reward and reset details.
Repeat the same egg/Cash measurement with the new level and unchanged temporary boosts. Record the before/after result and whether the limiting stage moved. If production rose but backlog now grows, the next useful spend may be processing or capacity rather than another production level.
Use the current panel. Update 8, balance changes, account state, or a later patch can make older tables unsuitable.
Do not estimate a hidden percentage. Capture the exact wording and measure a before/after result under comparable conditions.
Choose the one tied to the measured limiting stage, or wait until you can define a concrete next target.
A higher or newer level is not automatically the best next spend for your current farm.
The official text gives a count, not the names, costs, or benefit pattern.
A production upgrade can push the limit to processing, storage, or nest space. Remeasure after every meaningful change.
Both appear in Update 8 notes, but their relationship must be read from the current game interface.
Use the current game interface when a requirement, reward, or reset rule differs.
The official description says ten upgrade levels were added.
The official Update 8 description says two new Buy Tiers were added.
A complete current cost table is not in the captured official description. Read the panel in your server before planning a purchase.
Choose the displayed option that improves the measured limiting stage or a concrete merge/Rebirth target.
Record one stable minute before and after the purchase with the same flock, boosts, and processing behavior, then compare the result.
