In the game, you will control an excavator, which is a machine that can dig up earth and rocks. You can use the excavator to collect as many gems as you can.

There are many levels in the game, and the difficulty increases as you go down the levels. On each level, you will have an amount of fuel, and if you run out of fuel, you will have to go to the pump to refuel. The game also shows you an ad, and if you click on it, you will be transported to the pump.

In addition, there is a machine that you can use to swap your gems in exchange for coins.
