Deep Mine

Aim your hook, haul valuable ore, and build a mining operation across 12 depths. Choose an upgrade path, then push into the endless mine.

Rules

  1. The hook swings automatically. Tap the mine to aim, then press Drop hook or Space. Arrow keys fine-tune your aim.
    How it works: Aim, launch, then reel the ore all the way back. Heavy ore pays more but takes longer.
  2. Ore varies in value and weight. Heavy gold pays well but takes longer to haul; gems are light, while rocks obstruct the hook. Meet each depth's quota before time or fuel runs out.
  3. Press B or Blast to detonate dynamite at the hook. It clears heavy objects and cracks core armor, but destroys nearby ordinary ore too. Explosive barrels and green gas cost fuel and time.
  4. Choose a side contract at each depth for extra pay. Once the quota is met, bank early for remaining-time and fuel bonuses, or keep digging for more ore.
  5. Between depths, buy winch, engine, gem, drill and shield upgrades or supplies. Every third depth contains an armored core: strike it repeatedly or blast its armor before hauling it.
  6. Complete all 12 campaign depths to unlock endless play with your equipment. One paid rescue per run can skip a missed quota. Identical seeds give identical ore layouts. Progress autosaves locally. P pauses; rules and background tabs pause automatically.
