What Is TattsLotto?
TattsLotto — known as Saturday Lotto in NSW/ACT, Gold Lotto in QLD, and X Lotto in SA — is Australia's original and most popular weekly lottery, from The Lott, drawn Saturday nights at 8:30pm AEST with a minimum Division 1 prize pool of $4 Million. The game has been running since 1972, making it one of the longest-running lottery games in the southern hemisphere.
How the Draw Works
From a barrel of 45 numbered balls: 6 winning numbers are drawn, then 2 supplementary numbers from the remaining 39. The supplementary numbers determine winners in Divisions 2, 5, and 6. There are 6 prize divisions in total, giving players multiple ways to win from a single entry. A standard game costs approximately $1.20, with system entries available for players who want to cover additional combinations.
Prize Division Breakdown
| Division | Match Required | Typical Prize | Odds |
|---|---|---|---|
| 1 | 6 winning numbers | $4M+ (jackpots) | 1 in 8,145,060 |
| 2 | 5 winning + 1 supplementary | $5,000–$15,000 | 1 in 678,755 |
| 3 | 5 winning numbers | $500–$1,000 | 1 in 36,689 |
| 4 | 4 winning numbers | $25–$40 | 1 in 733 |
| 5 | 3 winning + 1 supplementary | $15–$25 | 1 in 297 |
| 6 | 1 or 2 winning + 2 supplementary | $10–$15 | 1 in 144 |
The overall odds of winning any prize in TattsLotto are approximately 1 in 85 — making it one of the more favourable lottery games from a "any prize" perspective. TattsLotto's 1-in-8.1M Division 1 odds are dramatically better than Powerball (1 in 134.5M) or Oz Lotto (1 in 62.9M).
Superdraws and Megadraws
Several times per year, TattsLotto runs Superdraw ($20M) and Megadraw ($40M+) events with dramatically increased prize pools. These typically generate 3–4× normal ticket sales and are announced well in advance, making them popular events for occasional players. Approximately 6–7 Superdraws are held each year, with the biggest end-of-year Megadraws typically held in the weeks before Christmas.
During Superdraws, the increased ticket sales mean Division 1 is more likely to be won, but also more likely to be shared. Our data shows the average number of Division 1 winners during Superdraws is 3–5, compared to 2–3 in standard draws.
Historical Trends from Our Data
Looking at the full TattsLotto dataset since 2008, here's what the numbers say:
- Division 1 is won in approximately 60–65% of standard draws
- Average 2–3 Division 1 winners per won draw
- Most winning sets contain a balanced mix of odd and even numbers (typically 3/3 or 4/2 splits)
- Numbers above 31 appear just as often as lower numbers — the "birthday bias" means picking higher numbers could reduce prize sharing
- The most common number sum range for winning draws is 100–180
- Consecutive number pairs appear in roughly 40% of winning draws
System Entries and QuickPicks
TattsLotto offers QuickPick (random terminal selection — roughly 70% of Division 1 wins come from QuickPicks), System entries (select 7–20 numbers for all possible combinations), and marked entries (manual selection). Our number generator helps with data-informed manual selections.
How TattsLotto Compares to Other Games
TattsLotto's 1-in-8.1M Division 1 odds are the best of any major Australian lottery. Combined with a $4M minimum jackpot, regular Superdraw events, and a cost of $0.75 per game, it's arguably the best overall value for the average player. Weekday Windfall shares the same odds but offers a fixed $1M prize; Powerball offers much larger jackpots but at 1 in 134.5M odds.
