Weekday Windfall Prizes and Odds

See every Weekday Windfall prize division, the official odds for one standard game and exactly how your Division 1 chance changes when you enter more distinct combinations.

Weekday Windfall prize divisions

Division 1: 1 in 8,145,060 for one standard game. The Lott’s responsible-play material publishes the overall chance of winning any Weekday Windfall prize as approximately 1 in 86 per standard game.
Division 1 prize $1 million

Paid to each of up to six Division 1 winning standard entries. If there are more than six, the maximum $6 million Division 1 pool is shared equally.

The divisional odds above are rounded to the familiar published “1 in N” form. They apply to one six-number standard game. The two supplementary numbers are the seventh and eighth balls drawn from the same 45-number barrel.

How do your Division 1 odds change with more games?

For Division 1 there is one winning six-number combination among 8,145,060 possible combinations. If every game you enter is different, adding more games gives you that many distinct combinations in the draw.

This is a mathematical combination comparison, not a recommendation to spend more.

Combination coverage10 / 8,145,060How much of the complete six-number combination space is covered.
Distinct matters: entering the same six-number line twice does not give you two different Division 1 combinations. It can duplicate the prize attached to that line if it wins, but it does not cover a second possible winning set.

System and Pick entries are bundles of standard combinations

A System entry selects more than six numbers and expands them into every six-number combination within that selection. A Pick entry works in the opposite direction: you lock in four or five chosen numbers and the lottery system combines them with numbers you did not select.

System example

System 8

28 standard combinations

Choosing eight numbers creates C(8,6) = 28 six-number games. If all 28 are distinct, the Division 1 chance is 28 in 8,145,060 — equivalent to about 1 in 290,895.

Pick example

Pick 5

40 standard combinations

The authorised rules give Pick 5 as an example producing 40 six-number combinations. That gives a Division 1 chance of 40 in 8,145,060 — about 1 in 203,627.

How the Weekday Windfall prize pool works

Division 1 is the unusual part of Weekday Windfall. For draws from 20 May 2024, the authorised rules provide $1 million for each of up to six Division 1 winning standard entries. If there are more than six Division 1 winners, $6 million is split equally between them.

Divisions 2 to 6 work as draw dividends rather than guaranteed fixed amounts. The rules set reference allocations for those lower divisions, and the money allocated to a division is divided equally between the winning standard entries in that division.

The rules also allow approved adjustments to those allocation percentages and specify what happens if a particular lower division has no winners, so the actual dividend should always be taken from the completed draw result rather than estimated from the percentages alone.

Why more games improve the odds but do not make a number “due”

Buying more different combinations covers more of the 8,145,060 possible six-number sets. That is the only reason the Division 1 probability improves. It does not make any particular number hotter, colder, overdue or more likely to appear.

A QuickPick and a valid line you choose yourself have the same probability. Historical frequency can describe what has happened in previous draws, but each valid six-number combination has the same Division 1 chance before a new independent draw.

If you want random valid lines rather than choosing them manually, use the Weekday Windfall number generator.
