Explore updated overdue lottery numbers for the longest time based on historical and latest draw history. This analysis highlights numbers that haven’t appeared for several draws and may be statistically considered "due" for selection.
Overdue Numbers
The table below presents key metrics for analyzing overdue numbers. It includes columns for Maximum Interval, Average Interval, and Last Draw Interval, which indicate the longest gap, the average gap, and the number of draws since a number last appeared, respectively.
Two additional columns, Average Rating and Maximum Rating, offer deeper insights into recent trends. The Average Rating is calculated by dividing the last draw interval by the average interval, showing how the most recent gap compares to typical spacing. Similarly, the Maximum Rating is obtained by dividing the last draw interval by the maximum interval, providing a measure of how close the current interval is to the longest ever recorded. Together, these statistics help identify numbers that may be overdue or performing unusually based on historical patterns.
To identify lottery numbers that may be overdue, attention should be given to the column Last Draw Interval, Average Rating, and Maximum Rating. A higher Last Draw Interval value indicates that the number hasn’t been drawn in a while and could be considered overdue. If the Average Rating is greater than 1, especially significantly so, it suggests the number has gone longer than usual without being drawn. Meanwhile, a Maximum Rating value close to 1 implies that the number is nearing or exceeding its historical maximum gap, reinforcing the idea that it may be overdue. Therefore, numbers with a high last draw interval, an average rating well above 1, and a maximum rating nearing 1 are likely candidates for being considered overdue.

Format Changes in Australian Powerball
The Australian Powerball lottery has undergone several format changes since its launch in 1996, each significantly impacting how number frequency analysis should be conducted. Below is the timeline of the Australian Powerball format changes:
| Period | Format | Powerball |
|---|---|---|
| 1996-2013 | 5 numbers from a pool of 45 (5/45) | 1 number from the same pool of 45 |
| March 1, 2013 - April 12, 2018 | 6 numbers from a pool of 40 (6/40) | 1 number from a separate pool of 20 (1-20) |
| April 13, 2018 - Present | 7 numbers from a pool of 35 (7/35) | 1 number from a separate pool of 20 (1-20) |
From 1996 to 2013, the game followed a 5/45 format, where players selected five main numbers from 1 to 45 and one Powerball from the same pool. In March 2013, the format changed to 6/40 + Powerball 1–20, meaning players had to choose six main numbers from 1 to 40 and a Powerball from a separate pool of 20. This shift altered the odds and made previous number frequency data less relevant. Then, in April 2018, the format changed again to its current form: 7/35 + Powerball 1–20. This increased the difficulty of winning the jackpot but introduced more prize divisions and larger potential jackpots.
How Australian Powerball 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 frequently in the 5/45 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 6/40 or 7/35 formats. Furthermore, changes to the Powerball pool—from 1–45 to 1–20—also significantly affect how often specific Powerball numbers appear.
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.
