Princess Cookie Monster

I created my first raffle the other day, but I still don't understand what happened. I set the time limit for 2 hours and the entry limit for 500. About 10 minutes went by, there were 93 entries, and the raffle had ended... What happened? I'm pretty new to the site and, like I said, it was my first raffle so I have no idea what could have happened there. Any ideas?
