Players compete to be the first to push six of their opponent's marbles off the board. The rules are easy and can be learned by almost anyone within a minute or two: You can push one, two or three marbles at a time. Your marbles can move one space, in a straight line or laterally. Two marbles can push one and three marbles can push one or two of your opponent's marbles. However, an equal number of marbles cannot push each other (ie: 1 cannot push 1, 2 cannot push 2, etc). That's it. It's a simple, fast moving and fun game involving subtle and profound strategy. With 4 million copies sold in over 30 countries, Abalone is one of the most popular strategy games of all time.
