You are probably referring to some other contest since there are multiple contests like this one running simultaneously usually on this site.
Previously you wrote about 10 grand exclusive bitcointalk contest so I guessed you are talking about the 10 grand bitcointalk contest opened by Hhampuz 10 days ago in the games and rounds board. Let me do another guess, are you referring to the contest posted by Russlenat? If it is correct, Russlenat himself seems to be a little bit confused because he asked about 10k Bitcointalk exclusive contest but he took a link from the website which has no relation to the bitcointalk exclusive contest. As long as I know there is no bitcointalk exclusive contest which is listed on the tournament page of duelbit's official site. The only 10k bitcointalk exclusive contest is the one posted by Hhampuz Duelbits.com | $10,000 Monthly Leaderboard | Bitcointalk Exclusive | Ends Nov 10
