What the shaft pays
Every number on this page comes from the live server and refreshes every 15 seconds.
The vault
Every reward is paid from one vault contract. The server can only sign vouchers for SHAFT that is in it, so the game can't pay out more than the vault holds.

Rewards are scaled so the free part lasts a set number of days at the current number of rigs. More rigs means a smaller reward each. If the free part runs out, digs pay nothing until more SHAFT is added to the vault.
Where the ore came from
This counts the last rounds the server reports. Each band's height is that depth's share of the draw; its bar is the SHAFT paid there.

Depths
Each round's depth is drawn at random with these odds. The reward for a right answer is random inside the range.

What one rig earns today
At today's rewards, for a rig that stays online and gets every dig right. Wrong and missed digs pay nothing, and rewards shrink as more rigs join, so treat this as a ceiling, not a forecast.
