The skill system gives you the chance to improve your mines, managers, and other features
There are 7 different skill trees.
You need 5.6T normal Cash to unlock the Research Island. To unlock the skills in the trees you have to use Research Points (Skill Points), which you can either earn (via Daily Rewards or Event Mine rewards) or buy in the in-game shop with Super Cash.
Green skill points can only be bought with normal Cash, blue skill points only with Ice Cash, red skill points only with Fire Cash, pink skill points only with Dawn Cash, purple skill points only with Dusk Cash, turquoise skill points only with Ancient Cash, and electric blue skill points only with Underwater Cash.
You can reset all seven skill trees and regain your skill points for 400 Super Cash , if you want to use them differently. Or you can reset & regain skill points for specific continents for 100 Super Cash each.
Each skill can be levelled up, so that the bonuses will increase.
