Mining
Mining lets you spend energy to earn bonus resources. Each mine targets a specific resource and rewards you based on your current production of that resource.
Energy
Energy regenerates passively over time. A full recharge from 0 to max takes 14 hours.
You don't need to wait for a full recharge — you can mine as soon as you have enough energy.
Mining Rewards
Each mine costs 1 energy and rewards 0.2% of your daily production of the targeted resource.
| Your Daily Production | Reward per Mine |
|---|---|
| 96,000/day (4,000/hr base) | 192 |
| 144,000/day (6,000/hr with buildings) | 288 |
| 480,000/day (20,000/hr late game) | 960 |
Variance
Each mine has a ±20% random variance on the base reward. For example, a base reward of 288 could yield anywhere from 230 to 346.
There is also a 2% chance to hit a 10x jackpot, multiplying your reward (after variance) by 10.
Strategy
You choose which resource to mine each time. Two common approaches:
- Mine what you need — If you're short on a specific resource for an upgrade, mine it to close the gap faster.
- Mine your strongest resource — If one resource has high production (e.g. from planet bonuses and building upgrades), mining it yields a larger absolute reward.
