It might be a little bit difficult to keep track of numbers when you don’t have a piece of paper. Many users keep score the same way that you would while playing a game of tennis- you would announce the score out loud every time you serve the birdie. There are a lot of products out there, however, that has a scoring system built right into the net. Typically, along the bottom of the next there is a line of numbers that range from 1 to 21, and a slider that you can slide along the bottom. Every time that your team scores a point, you can slide the indicator along the bottom to track your score. If you aren’t really into competing, and you just want to have a good time, hitting the birdie back and forth is a lot of fun without adding in extra competition.
