About

Gem Mining Robot

Features
Read full description

A casual game for a self-propelled robot that specializes in digging gems. It has enough power, and with a powerful laser launcher, it can evaporate clay and move almost unimpeded underground. It also has front and rear cannons that can destroy various monsters underground. But it must be able to fire after digging at least one gem. This robot is not omnipotent. It does not know where the gems are, nor where the monsters are. It needs your operation to complete the task. 1. The direction of advance: You need to indicate the direction of advance for it (by gently swipe to up, down, left or right) 2. When to fire: There are various monsters that can automatically track it, and as long as they touch it, the game will over. Therefore, it is best to shoot the monsters before they approach, and of course the score will be consumed. 3. Do nothing about the stone: it can only go around the stone and move forward. However, for the stone that has no obstacles in front or is at the edge of the tunnel, just push it lightly to break through the obstacles and continue to move forward. Because stones can kill all kinds of monsters, in order to save score, it is best to use stones to kill such monsters. Main operations: 1. Swipe: Slide your finger up, down, left, and right anywhere on the screen to change the direction 2. Tap: Tap the location around the robot to fire. Notes: Internet is must to play this game.
