To play the game, use the picks to dig up all the gems in the mine. You can do this by clicking on the picks at the bottom of the screen and then clicking on the areas of the mine where you think the gems are buried. As you collect the gems, you'll need to build a path for your cart to follow. To do this, choose a type of track from the options at the bottom of the screen and then click to place it on the mine. You can click on the track again to rotate it. Be sure to collect the picks in the same order that you collect the gems, and try to complete the level as quickly as possible to set a new high score!
