Nine winners last weekend? Believe it or not, one person in the Crows tipping competition managed to select all the victors in round six.

The weekly winner was Jacqueline Constable, who will receive a $50 CROWmania voucher after somehow tipping nine winners from a round featuring several upsets.

The leaderboard has tightened at the top, with five tipsters locked on 39 from a possible 54, followed by a large group on 38.

Meanwhile, only 97 tipsters remain in the Gauntlet sub-competition after the first two rounds. Hawthorn’s loss to Greater Western Sydney wiped out many competitors..

If you survived, remember to pick one team you think will definitely win this weekend. There is a catch, however. Once you have picked a team you can’t pick them again in subsequent rounds.

The overall winner of the Crows Gauntlet competition will win a 2015 guernsey signed by the Crows squad.

The major prize this year is a ten-seat corporate box at Adelaide Oval for Crows home games in the 2016 season.

Runner-up will receive two tickets to this year’s Club Champion event and the third-placed tipster wins a team-signed 2015 Crows Guernsey.

Signed Crows guernseys will also be the prizes for the Gauntlet and Pick 5 mini-competitions.

And the best tipster each round will received a $50 voucher from CROWmania.
