Don't worry, change is a natural and beautiful thing that occurs in nature every day.
You will notice that your Fanball Number may change from day to day. We take a look at things like your most recent contests and weight them a little more than we do contests that happened in the past. So if you've hit a big winning streak, you are likely to see your Fanball Number go up. Conversely you could see your Fanball Number go down at times as well.
Depending on where your Fanball Number is today, you will see some different contests and games that are exclusive to those within your range of Fanball Numbers. Granted there are still open contests that you can join at any time regardless of number, but your available slate of games could be different from friends who have a different Fanball Number.
Embrace change. Change is good.
