Gemstone Tycoon is an amazing online flash game where you are represented to the 65 levels to overcome. Each plot has the different heading: the first one comes with east station, then Brewster mine, the old rails, central crossroads, golden land and finally, the red hill. Each game has the main objective: you are the driver of all the trains so that you can manage the direction and speed in the way so there are no collisions in the end. Please bear in mind that the trains are carrying heavy gemstones with them and the scores you earn after each level highly depend on which collision the game ended.
