Imagine a game with 1 in 4 odds has 4 million tickets - 1 million of those will be winners. Imagine putting all 4 million tickets into a giant bag and shaking them so they mix up randomly. The odds of winning will be 1 in 4, but that doesn’t mean if you reach into the bag 4 times then you’ll be guaranteed to pull out a winning ticket. It's the same with the Scratch'n'Win tickets that you buy - they are printed and randomly sent out to Lotterywest retailers across Western Australia, so your chance of winning for each ticket is 1 in 4 across all tickets sold in WA.

S'n'W overall Odds for a game = Total number of tickets / Number of winning tickets
