Deepvein Mine Tycoon

Four claims wait on the survey map: the green hills of Hollowfield, the red cliffs of Redmesa, the grey coast at Tidewater and the hot basalt of Ashcrown. Each one pays more the deeper you dare to dig, and every sale buys the next claim.

A side-view mine tycoon: dig ore, lift it up and sell it. Upgrade the slowest station, hire managers, dig deeper and sell the mine for a lasting bonus.

Your mine is a column of shafts under a lift. Tap the miners in a shaft to dig one load into the crate at the lift door, tap the lift to carry the crates up, and tap the cart to haul the ore to the market, where it turns into cash. Each station has its own upgrade: shafts dig more per trip, the lift carries more per ride, the transport gets bigger and more carts. The strip under the mine shows what each station moves per second and marks the slowest one, because that station sets your income. Levels 10, 25, 50 and 100 double a station's output and add a miner or a cart. A manager runs a station on its own, keeps it earning for up to two hours while you are away, and has an ability on a timer: Rush doubles digging speed, Express doubles lift speed, Big load doubles cart loads. Build new shafts to reach new ore; the rock changes from topsoil to bedrock, crystal caverns, magma and the deep core as you go down. Once you reach the sale depth you can sell the mine: the next site opens with a higher income multiplier, and the bars you earn buy permanent research. Redmesa has cave-ins you tap clear, Tidewater floods its deep tunnels unless the pump keeps up, and Ashcrown overheats tunnels unless you vent them. The daily shift gives everyone the same fresh mine for five minutes; your score is the cash you earn.
