Minerals have been overflowing on a distant planet and we need to collect it now! These resources will help us upgrade the mothership, and the planet we need to discover is Sagittarius: 2172. All we need to do is align those falling metals and crystals from the screen, and create a matching pair of 3. You will receive money as you clear lines. Lines that you need to clear are either horizontally, vertically, and diagonally. There are also skills that you can use to aid you in harvesting. But these skills also have a cost and a limit so watch out.
