Mercury Regions

Mercury has several regions, each divided into areas which contain 10 layers. The last layer in each area has more health points (HP) than the first nine layers in that area. At the end of area 5, 10, 15, and 20 in each region is an obsidian layer. At the end of area ? in each region is 3 obsidian layers.

Digging on Mercury sometimes create mercury drops which can be used to buy bonuses.

"Normal layer" health (Area 1 to 9 of each region) approximately follows the following function:

$${hp = 1.806 \times 10^{21} \times (1.163759209)^{area number - 1}}$$

Layer 10 has 5 times as much hp as normal layers.

The core layer has $${1.287 \times 10^{50}}$$ hp.
