Only four tipsters picked all nine winners in the opening round.

A tipster with the username Prostyle was the first weekly winner in the 2015 Crows Tipping competition after being only five points off the margin in the first game of the round. They will receive a $50 CROWmania voucher.

It’s not too late to get involved in the competition, even if you missed the opening. Latecomers will automatically receive three points from the first round (away wins)
