Hi everyone,
I'm also confused in receiving the award. I would like to share with you what I know.
Winning number is 15. I saw someone choose 15, but he doesn't live in Vietnam, Lao, Cambodia so he didn't become a winner. The first prize will belong to numbers are 14 and 16. There are 3 people who picked 14 & 16. 1st prize will be 25/3 = 8.3 steem. 2nd prize is 13 & 17. There are 8 people who picked 13 & 17. But 2 of them don't live in Vietnam, Lao, Cambodia. 2nd prize will be 15/6 = 2.5 steem. 3rd prize is similar. You need to comment on post that how much you won. ^^
