Show us your management skills in this dynamic traffic management game!! The drill is pretty simple: you supervise a gold mine and the things got a little bit hectic there. Plenty of work, wagons full of gemstones, golden ingots and lots of trains rushing on the railways. To avoid an accident, keep an eye on the traffic. You will have the ability to stop the trains or to boost their speed with NOS. It may sound simple but it's really challenging to maintain your focus on every railway. And because everybody is in a hurry there is no order in which this trains go so you will need to be really careful so one click to stop the train, double click to boost its speed.There is a normal mode and survival mode. Each mode has 6 levels. The normal mode starts from easy and reaches the impossible level so consider yourself warned and challenged. Enjoy Gemstone Tycoon!
