There are three fields. One that is normal. The other has little black numbers on it. My clumsy fingers sometimes have trouble lining things up with the lines, so I use a marker to cover the number where the ball is located. The third eliminates the scoreboard and has a bigger time clock on it.
There is a sheet of various markers that you can cut out and use whichever ones you prefer, or make your own. I sometimes use buttons as well.
