Dig down to find the ultimate Diamond - upgrade your robot to dig deeper.

Falling Rocks makes it hard to get some ore but your robot have to survive.

You start at a very small mine where you can make your first experiences and find your first money and of coure the first Ultimate Diamond.

Soon you will proceed to the next mine - each mine is deeper than the mine before and so you will find different types of ore, which you can mine. At some point you will also find many types of gems of even more value.

Spend your findings at your UFO to buy upgrades for your little robot to make mining life easier for you.

Watch out the falling rocks, don't get lost deep down the mine or you have to abondon your little robot.

You will need some kind of thinking where to dig so you can always come back to light.

Your robot will sooner or later run out of energy and needs to visit the UFO for a recharge of battery, ladders and support pillars.
