This site is so confusing to me. They still have sweeps up that are expired. Sometimes you have to keep refreshing the page to see new sweeps because they are like ads. Then it says you can enter as many times as you want.
I signed up my 13 year old and when I see active sweeps I'll enter like 10x each, but probably not very good odds. LOL Looks like they have some new ones up today though.
