50 marbles of each color are provided but the game may be played with less marbles as long as both sides start out with an equal amount. To play this game you start by rolling a dice to see who will go first. Each player will then roll the dice twice for each move to be made, but only moves marbles after the second roll. The first roll is the determining number. In the second roll there are three possibilities. If the second number is less than the first roll, you have to give your opponent the amount of your colored marbles you rolled the first time. If the second roll is higher, then you subtract your first role from the second and take that many of your opponents marbles or take your own colored marbles back along with any of your opponents to complete the number amount. If you roll the same number both times (same dice combination), you get to take the total of both roles of your opponents colored marbles or a combination of yours and your opponents to match the total number. If you roll the same total numbers again, then you pass the turn on to your opponent without moving any marbles at all. The game ends when one side has lost all of their own colored marbles.
