Your rewards will be multiplied by 2, 3, or 4 depending on how far the gnomes have been able to travel.

The bonus game will be made available to you if you manage to gather five railroad fragments while the Railtrack function is active. Three gnomes will be placed in mines for this round as they compete against one another for precious metals. In the lower portion of the playing field, there are three wagons that you must choose one at a time. One of the gnomes will advance based on which precious metal is in the wagon you selected. Whichever gnome crosses the finish line first will determine the size of your ultimate reward.
