Oz Lotto History
Early Years
When Oz Lotto began operations in 1994, it mirrored the structure of Saturday Lotto, with players selecting six numbers from a pool of 45. The game was administered by Tattersall’s and quickly gained popularity as Australia’s unified national lottery game. Initial entries cost $1.20 per game plus agent commission.
Major Changes
The Seventh Ball Addition
A significant transformation occurred on October 18, 2005, when Oz Lotto introduced a seventh main number to its draw. This change substantially increased the odds of winning Division 1, making them nearly comparable to Powerball’s odds. The addition of the seventh number led to larger jackpots and more excitement around the game.
Regional Branding Evolution
The seventh ball addition sparked various regional branding initiatives:
- Tatts regions marketed it as “Super 7’s Oz Lotto”
- Queensland branded it as “Oz 7 Lotto”
- By 2012, all regions returned to the unified “Oz Lotto” branding
Recent Developments
In May 2022, Oz Lotto underwent its most recent transformation when The Lott implemented a significant change to the game’s matrix. The pool of numbers increased from 45 to 47, and an additional supplementary number was added to the draw. This modification further affected the odds and prize structure of the game.
