This chart shows the distribution of odd and even numbers over a series of draws to spot number biases. Players may use these to balance their number selections to have a better chance of matching draw results
Odd/Even Number
The chart below visually represents the distribution of odd and even numbers over a selected range of draws. Each bar corresponds to a specific draw, and it is divided into two segments: the lower segment represents the count of odd numbers drawn, while the upper segment shows the count of even numbers. This makes it easy to compare the proportion of odd and even numbers within each draw, as well as observe any trends or imbalances over time. The total height of each bar indicates the total number of numbers drawn per draw.
Odd/Even Number Summary
This summary categorizes each draw by how many odd and even numbers it contains, making it easy to identify the most common distribution patterns across all draws in the selected period. To complement this data, a donut pie chart visually represents these groupings, with each slice corresponding to a specific odd-even combination. The size of each slice reflects its relative frequency, offering a quick overview of how often each odd-even balance occurs.

Format Changes in Australia's Set For Life Lottery
Since its inception in August 2015, Australia's Set for Life lottery has undergone significant changes to enhance gameplay and increase winning opportunities.
| Period | Format | Supplementary Nos. |
|---|---|---|
| August 2015 - March 22, 2020 | 8 numbers from a pool of 37 (8/37) | 2 numbers from the same pool. |
| March 23, 2020 - Present | 7 numbers from a pool of 44 (7/44) | 2 number from the same pool |
Since its launch in August 2015, the Australian Set for Life lottery has undergone notable changes aimed at improving gameplay and enhancing player experience. Initially, players were required to select 8 numbers from a pool of 1 to 37. Each draw produced 8 winning numbers and 2 supplementary numbers.
On March 23, 2020, significant revisions were introduced. The format changed to selecting 7 numbers from a larger pool of 1 to 44, and each draw now produces 7 winning numbers and 2 supplementary numbers. The number of prize divisions expanded to eight, with players now able to win a prize by matching as few as 3 main numbers and 1 supplementary number. These changes also improved the overall odds of winning a prize, shifting from 1 in 59 to 1 in 50. Overall, the modifications were designed to create more frequent and appealing prize opportunities for participants.
How Australia's Set for Life Lotto Format Changes Affect Your Number Strategy.
These format changes have a direct impact on statistical analysis. Mixing frequency data across different formats is not advisable because each version of the game has a different number pool and probability structure.
For example, a number that appeared less frequently in the 8/37 format may have done so due to lower individual draw probability, but that same frequency can be misleading in the 7/44 formats.
Therefore, for meaningful analysis, it’s essential to treat each format as its own distinct dataset. Analyzing trends or frequencies should be restricted to results from within the same format period, especially if the goal is to inform number selection in the current game structure.
