This is a very challenging puzzle game. You need to collect gems by clicking on the boxes of corresponding colors according to the colors of the gems. There are 7 locations to store boxes. If the locations are full, the game fails. There is a drill in front of each location. You need to collect the diamonds on the surface before you can collect the gems deeper. With each level, the terrain of the mine will become more tortuous, and the arrangement of gems will become more elusive. You need to reasonably distribute large and small boxes according to the number and color of gems on the wall to successfully pass the level and win.
