Three answers for you.
1. I don't understand how to win against a guess because no lottery in FOD, but guest. 
2. Some guests are fake, you never know how good are the guests. If they are weak, you are lucky. If they are very strong, you are unlucky. Some players will complain about this if they lose.
3. This site lacks registered members. This can encourage people to register into this site, if they want to be more excited. 

Points cant be noticed on a guest player because it doesnt have any sort of player information details.
