If you go to mymohegansun.com and sign in your current point balance is shown in the first page that pops up. My experience is that the data is directly tied to their system so the information is "live".

It doesn't really matter how it's done. I know we can go to a booth and they can check our point activity but sometimes I want to see it myself, to make sure they don't double charge or something like that.
For example, at restaurants, they don't always ask for ID.
