Saturday Tattslotto Ticket is a product of Tattersalls. This section refers to the national Saturday night draw, syndicated to all Australian states and territories through the Australian Lotto Bloc. The game is marketed as "Tattslotto" in Victoria, Tasmania, Australian Capital Territory, and the Northern Territory; as "Gold Lotto" in Queensland; and as "Lotto" or "Saturday Lotto" in New South Wales, South Australia and Western Australia.

Tattslotto's first draw was on June 22, 1972, televised on HSV-7 Melbourne, and it became a Lotto Bloc game in March 7, 1981. Saturday Lotto's draw numbers have only used odd numbers since Draw 233 on 1983-10-15 - this allowed some jurisdictions to use the even numbers for midweek games.

A player purchases a number of "games" by either marking numbers on a computer-scannable ticket or by requesting a random selection (known variously as a "Quick Pick", "Auto-Pick", "Easi-Pick" or "Slikpik"). Games where a player selects six numbers only is known as a Standard game and these are often played in multiples of two. More than six numbers can be selected per game - known as a Systems entry (e.g. 'System 7' is where seven numbers are selected) - but the cost of that game rises as the odds of winning increase. Some states also allow you to select only 5 or 4 numbers, with those numbers being combined with every combination of the remaining numbers (giving the equivalent of 40 and 780 standard games respectively). This is sometimes also referred to as a Systems entry - e.g. 'System 5' - or as a 'With the Field' entry.

In a Tattslotto draw, six numbers and two supplementary numbers are drawn from a barrel of 45 numbers. The following prize divisions can be won:

First Division (Jackpot Average $700,000) - All six winning numbers in a game.
Second Division (Average: $12,000) - Five winning numbers and one supplementary in a game.
Third Division (Average: $1,000) - Five winning numbers in a game.
Fourth Division (Average: $50) - Four winning numbers in a game.
Fifth Division (Average: $24) - Three winning and one supplementary in a game.
