Ok thx for the answers, that happened just once that i got 1000 satoshis extra, maybe it is mistake by freebitco.in moderators because i didnt won on free roll or multiply game anything special and have only one refferal who is inactive. I am writting from the phone so i dont know how to post picture of that, my final winnings after match Bayern Munich- Borrusia Dortmund were 50 satoshis and that is official, but after that game i had 1000 satoshis more. Information about that i tried to find on my profile stats but i didnt find it anywhere. 
Re-check your account deposit history, there must be a reason for you to receive additional 1000 sats. But what makes i confused, do we can betting with less than 100 sats on sports? It really worthless and just wasting time to bet with such low amount like that
