Lodebound
dig, get shafted, repeat.
A mining game on the Robinhood Chain. Dig for ores and INGOTs while you're away. Upgrade your pickaxe. Pickaxes let you venture deeper into the shafts, and the shafts are where the big INGOT deposits are. The better your pickaxe, the deeper you go, the more you earn.

The short version
The passive part. Pick a deposit, pay for lamp oil, come back in about half an hour for three to seven lumps of ore and a small payout of INGOT. Slow, but it adds up.
Twenty lumps of one ore plus some INGOT makes that ore's pickaxe. A better pickaxe survives deeper. You can hold three.
Where you earn. Pay the entry and walk down shaft by shaft. Each floor holds a bigger vein of INGOT than the last, and a bigger chance of a collapse that takes your pickaxe.
The token
INGOT is the only currency in the game and the only way to get it is to buy it. Nothing in the camp is given away and nothing you dig up can be sold at the moment. Ore makes pickaxes, pickaxes go down the shafts, and the shafts are the one place INGOT comes back out of, paid from the game's Treasury.
Meet Wick
Wick runs the claim office, which is a stool next to the shaft. He'll sell you the bronze pickaxe for 250 INGOT. It's a one-time payment, and he'll tell you the money gets put to good use.
