Deep Drill

About Deep Drill

Deep Drill is an idle mining game where your drill steadily burrows downward, automatically collecting ore as it goes. Instead of a traditional home screen, the action starts immediately, and you can invest ore to improve your rig’s components, making drilling faster and more efficient. The deeper layers become harder and yield less ore per meter, challenging you to find the most profitable depth before deciding to seal the well. When you reset, you earn cores that unlock permanent upgrades, helping you progress further in future runs. The game runs continuously, including while the tab is closed, so your investment decisions focus on long-term growth rather than active play. Deep Drill offers a straightforward yet strategic experience in incremental resource management and mining.

How to Play

Mouse or touch — the drill descends by itself, so every input is a purchase.
Rig: press a row's price key to buy a level; the mode key switches between Buy x1 and Buy max, which spends the whole affordable ladder at once.
Cores: spend the cores a sealed well paid out on twelve permanent nodes. They survive every future seal.
Surge: x3 ore for eight minutes.
Salvage: seal the well — depth, ore and rig levels reset and your deepest point pays out cores.
Goal: get deeper. There is no time limit and no way to lose, and time offline keeps paying ore within your night shift's window.
