Miner, Dig It All

Your drill has one tank of fuel. See how deep the pit lets you get!

Drag to lay a line of dynamite, fire it, then hold the drill to grind the shattered rock away. Clear the layer and it collapses under you, straight into a richer one. On the surface, sell the ore and buy a harder bit, wider blasts and a robot crew, then dive again. Ten layers down sits the lava core: crack it and the whole pit starts over, permanently richer!

• Mouse: hold the left button to drill. Hold and drag to lay a line of dynamite, a single click plants one stick. Right click fires the charges early.

• Touch: tap to plant a stick, drag to lay a line, hold to drill. The charges fire on their own.

• Space fires the planted charges.

• Esc or Tab pauses.
