Dows anyone know what the small arrow with in a number in it is for at the bottom of my pet rescue saga screen? It's on my iPad and phone and the number changes between every life

I have asked one of my co-superstars to find out exactly as she is more of an expert than I am. She says its to show how many rows are left until the bottom of the game. 

Hope this helps!
