Fast answer
The answer before the background
For resource searches, first identify the exact wallet shown by your product. Current first-party premium listings explicitly name Gems, Crystal and Rune Key; a 2019 publisher reply also mentioned Ancient coins and Purple stars, but that old answer does not prove the present economy. Diamonds, gold and money are common search wording, not confirmed interchangeable balances. Farm the current bottleneck through repeatable stages, achievements or live events, and compare net useful progress per minute.
Currency evidence
Keep current, dated and unverified names separate
| Term | Evidence status | How to use it |
|---|---|---|
| Gems | Current paid Android product advertises 600 for new users. | Treat as a named premium-product reward, not a universal free balance. |
| Crystal | Current paid product advertises 120. | Preserve the singular store wording and verify the live wallet. |
| Rune Key | Current paid product advertises 20. | Match it to rune access in the installed edition. |
| Ancient coins / Purple stars | Mentioned in a dated 2019 publisher reply. | Historical evidence only until the present client confirms them. |
| Diamonds / gold / money | Not established as current wallet labels by the checked pages. | Do not merge them with Gems or Crystal because a query uses the word. |
Farm test
Measure the reward that reaches the next upgrade
Choose the upgrade blocking progress, write down its required resource and current balance, then run a repeatable stage or current event three times. Divide the net relevant reward by total minutes, including ads, loading and failed attempts. A harder level with an occasional large chest can be worse than a stable clear that feeds the exact upgrade.
Events are worth checking because the publisher has explicitly directed players toward them and recent store history continues to mention seasonal events. Their dates and rewards change, so record what the current client shows instead of turning one Halloween or Mid-Autumn result into a permanent route.
Spending order
Buy the bottleneck, not the loudest notification
- Fix a leaking lane before adding damage to a tower that never reaches the problem area.
- Concentrate early hero and rune spending on one tested plan rather than unlocking several unfinished alternatives.
- Keep premium-looking resources until the purchase screen or upgrade panel explains their exact function.
- Separate one-time achievement and paid-edition bonuses from repeatable farming income.
- After a version or product change, recalculate the route; free and premium app IDs should not share assumed balances or purchases.
A stage number without product ID, version, difficulty, completion time and net reward would be false precision. The worksheet above produces a route that can be retested after updates.
FAQ
Common questions
How do I get more resources?
Identify the wallet required by the next upgrade, test stable stages, achievements and current events, then compare net relevant reward per minute.
Are diamonds and gems the same?
The checked first-party pages do not establish that. Use the exact label shown by the installed product.
What resources are confirmed now?
The paid Android listing explicitly advertises Gems, Crystal and Rune Key in its fixed new-user benefit.
Are Ancient coins still current?
They appeared in a dated 2019 publisher response; confirm the current client before presenting them as part of today's economy.
