In Robo Miner you control a mining robot which is capable of drilling down the surface. Your order is to find the ultimate diamond located somewhere in each level. On your way you will find different types of ores and crystals providing you with instant cash. Spend this earnings to upgrade your robot to dig even deeper. Each Level will let you dig deeper and find more valueable ores.
You have to be careful where you dig and keep your robot from cave-ins and other dangerous blocks. Use dynamite to make your way trough undrillable blocks and find yourself using parachutes, scanners, ladders and pillars to get back to the surface and recharge your batteries. How deep can you get?
