Never won the big one - yet, but just this week I've won $21 on two different scratchies. Then I find a winning $10 scratchie someone had left on the bench of the Tatts place.
I always check them over etc and was surprised to find this winner! Usually it's because people don't quite understand the game. Years ago I had luck in town with the same thing so keep checking!
I've also won the bottom division, so about $10-15 per time, of the Saturday draw a few times now.
My neighbour was one of the first big winners when Oz Lotto began in the 1990's, it enabled him to move away from the country town where he'd grown up and to Melbourne.
