Source hierarchy
Official terms and current app listings take priority.
Game rules are checked against TerraMine's official website, player guide, Terms of Service, App Store and Google Play listing. When official sources disagree, the most current app-facing source is identified and the discrepancy is noted.
Reddit, Discord and independent guides are useful for fast-changing rewards and strategy discoveries. Those values are presented as community reports, not permanent official rules.
Calculator methodology
The math is visible and reproducible.
The calculator uses the displayed monthly level-one rates for Rock, Coal, Gold and Diamond mines, applies 1% for every level above one, then blends boosted hours at 20× with unboosted hours at 1×.
Results estimate the balance shown inside TerraMine. They are not a promise of withdrawable cash, profit or future rates.
Commercial transparency
The referral helps fund the guide.
TerraMineGuide.com uses referral code TM-7LH7M. When the current offer applies, both the new player and the referrer receive TerraBucks after the qualifying first claim.
Referral links are marked as sponsored. Editorial conclusions—especially cash-out warnings and risk information—are not changed to make the game appear safer or more profitable than the evidence supports.
Corrections
Fast-changing claims are dated and corrected.
Reward values, app wording and community statistics can change quickly. The date shown on each guide is the latest editorial verification date. Material changes are recorded on the guide changelog.
