With 18 potential winning picks left in 2015, the super main prize in our Crows tipping competition is set be decided on the last weekend of the minor round.

Seven tipsters are now locked on 135 points and leading the way in the chase for the major prize - a ten-seat corporate box at Adelaide Oval for Crows home games in the 2016 season.

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

Sam Thomas claimed the round 21 weekly prize, a $50 CROWmania shop voucher.

It’s not too late to get involved and chase the weekly prize. Join now
