Saturday Lotto prize divisions and official odds

These are the current official rounded odds for one standard six-number game. Lower-division prize amounts are not fixed here because the dividend can vary by draw.

Why Division 5 says “at least 1 supplementary”: the official shorthand is “3 winning numbers + 1 supplementary”. Under the current rules, a standard line with three winning numbers and either one or both supplementary numbers belongs in Division 5. A three-winning-number line without that supplementary match is Division 6.

How do my Division 1 odds change with more games?

For Division 1, the clean unit is the number of distinct standard six-number combinations you hold in the same draw. A ticket can contain many games, so “10 tickets” and “10 games” are not necessarily the same thing.

4 distinct games give four different six-number combinations.

This calculation is exact for Division 1 when the combinations are distinct. Two copies of the same six-number line do not create a second possible winning combination. They duplicate the prize entitlement attached to that line if it wins.

Why the Division 1 odds are 1 in 8,145,060

A Saturday Lotto standard game contains six different numbers selected from 45. The number of possible unordered six-number combinations is:

C(45, 6) = 8,145,060 possible standard combinations

Only one of those combinations can exactly equal the six winning numbers in a draw. That is why one standard game has a Division 1 probability of 1 / 8,145,060.

The two supplementary numbers are drawn afterwards from the remaining balls. They affect Divisions 2 and 5, but they do not form part of the Division 1 six-number match.

Winning numbersThe first six numbers drawn. All six are required for Division 1.
Supplementary numbersThe seventh and eighth numbers drawn. They help determine particular lower divisions.
Standard gameOne six-number combination. Official published odds are quoted against this unit.
Overall oddsThe chance that one standard game lands in any of the six prize divisions.

System entries: how many combinations are you really buying?

A System entry selects more than six numbers and expands them into every six-number combination within that selection. This gives you more distinct standard games and therefore a proportionally larger Division 1 chance — at a proportionally much larger entry size.

A System 8 selects 8 numbers and produces every possible six-number subset of those numbers.

System entries can also generate multiple lower-division prizes from one selected set because several of the underlying six-number combinations can qualify in the same draw. That is a different concept from simply saying “a System is more likely to win”.

What about Pick 5 and Pick 4?

Published Australian Lotto rules also provide fewer-number Pick/System formats. A Pick 5 fixes five chosen numbers and combines them with each possible sixth number, creating 40 standard games. A Pick 4 fixes four numbers and creates every possible pair for the remaining two positions, producing 820 standard games.

Pick 5 40 games Division 1: about 1 in 203,627
Pick 4 820 games Division 1: 1 in 9,933
Availability and naming: System and Pick products can differ by operator, jurisdiction and sales channel. The mathematical comparison above is based on the number of six-number combinations the entry represents, not on an old ticket price.

How Saturday Lotto Division 1 prizes are shared

The regular Saturday Lotto Division 1 pool is commonly advertised at an estimated $6 million, while special draws such as Superdraws and Megadraws can advertise much larger pools. The headline amount is a Division 1 prize pool, not a promise that one winning entry receives the entire figure.

If there is more than one Division 1 winning entry, the pool is shared between those winning entries. Using a $6 million pool purely as a simple illustration:

Illustration only. The final declared pool and official dividend for a particular draw control the actual payment.

What buying more games changes — and what it does not

More different combinations cover more of the 8,145,060 possible Division 1 outcomes. Ten distinct games therefore have ten times the Division 1 probability of one standard game: 1 in 814,506.

What does not change is the probability attached to each individual valid combination. A QuickPick, Slikpik, favourite-number line, birthday pattern or generator line has the same mathematical chance as any other specific six-number combination.

Past frequency does not alter the next draw. A number being “hot”, “cold” or overdue is a description of previous results, not an adjustment to the 1-in-8,145,060 Division 1 calculation.

Saturday Lotto odds FAQs

What are the odds of winning Saturday Lotto Division 1?

The official Division 1 odds are 1 in 8,145,060 for one standard six-number game. Division 1 requires all six winning numbers in the same game.

What are the odds of winning any Saturday Lotto prize?

Lotterywest currently publishes overall odds of approximately 1 in 42 for one standard game across Divisions 1 to 6.

Do supplementary numbers count for Division 1?

No. Division 1 is based only on matching all six winning numbers. Supplementary numbers are relevant to lower prize divisions, particularly Divisions 2 and 5.

If I play 10 different games, what are my Division 1 odds?

Ten distinct standard combinations have a Division 1 chance of 10 in 8,145,060, which simplifies to 1 in 814,506 for that draw.

Does a System entry improve the odds?

A System entry creates multiple distinct six-number combinations. For example, System 8 represents 28 standard games, giving a Division 1 chance of 28 in 8,145,060, or 1 in 290,895. The increased coverage also means a much larger entry.

Can a System entry win more than one prize?

Yes. Because a System contains multiple overlapping standard combinations, several of those combinations can win lower-division prizes in the same draw. Published operator System tables show the possible prize multiples for each match pattern.

Are TattsLotto, Gold Lotto and Saturday X Lotto odds different?

No. They are regional names for the same national Saturday Lotto draw and use the same 6-from-45 game matrix and prize-division odds.

Does buying the same line twice double my chance of Division 1?

No. The same six-number combination still covers only one possible winning combination. A duplicate entry can increase the amount you receive from that combination if it wins, but it does not create another distinct outcome.
