Gems[edit]
Gems are a premium progression currency used for account-level upgrades, utility spending, and acceleration.
They are not your main run currency, but they are extremely important for long-term power growth.
Main Uses[edit]
Gems are spent on:
- Boost purchases (random boost cards)
- Worker purchases (random worker progress)
- Mechanic upgrades
- Gem Upgrades (base/increase levels in Gem shop mode)
- Buying new server slots
- Skipping Download time (hour-based gem skip)
- A few utility actions (example: name change)
High-Impact Gem Spending[edit]
In most progression paths, these are your best-value gem sinks:
- Gem Upgrades (permanent scaling)
- Core utility slots/mechanics
- Boost/Worker growth (depending on account stage)
- Download time skips when timing is critical
How Gems Are Earned[edit]
Common sources include:
- Milestone rewards (major source)
- Boss-related reward outcomes
- Periodic claimable gem rewards
- Some game events/minigame-related rewards
- Ads/reward offers (when used)
- Store purchases (optional)
Gems and Download Skips[edit]
Downloads can be sped up with Gems using hour-based skipping.
Practical use:
- Strong for important unlock downloads
- Usually best saved for bottleneck downloads, not every timer
Strategic Importance[edit]
Gems are also indirectly valuable because some long-term systems scale with gem ownership (for example, daemon-based scaling effects).
So spending Gems gives power now, while holding Gems can also have scaling interactions depending on unlocked systems.
Practical Tips[edit]
- Don’t dump all Gems into one system early.
- Prioritize unlock-enabling progression first (slots/mechanics/key upgrades).
- Spend aggressively when it unlocks major account progression.
- Use skip-to-finish only on high-impact downloads.
Quick Summary[edit]
Gems are a flexible premium progression currency:
- used for permanent upgrades,
- used for utility acceleration,
- and critical for smoothing progression bottlenecks.
