This chart shows how often each individual lottery number has been drawn over a specific period or across all previous draws. This statistic gives players an insight into which numbers have been drawn more frequently or less frequently.
Number Frequency
The Number Frequency Statistics table below presents key metrics for analyzing the occurrence patterns of specific numbers. It includes columns for Frequency, Last Draw Interval, and the Last Draw Date, which indicates the number of draws a ball appears for a specific period, , the number of draws since the ball last appeared, and the date the ball last appeared, respectively.
| Ball | Freq. | Draw Interval | Last Draw Date | |

The Summary of Number Frequency by Rank organizes lottery numbers based on how often they have been drawn, grouping them into tiers or ranks according to their frequencies. Numbers with the highest frequencies are placed in the top rank, indicating they have been drawn most often and may be considered "hot" numbers. Subsequent ranks include numbers with gradually lower frequencies, offering a clear comparison of how commonly each number appears.
Percentile Rank shows the relative position of a number’s frequency compared to all others. It answers the question “What percentage of numbers were drawn less frequently than this one?”. Using the percentile rank you can compare easily by normalizing frequencies on a 0–100 scale, visualizes hot/cold numbers: You can chart numbers into low, mid, and high percentiles.
This ranking system helps highlight patterns in number occurrences, making it easier to identify which numbers are most frequent, moderately drawn, or rarely drawn. It provides a useful overview for players looking to base their number selections on historical draw performance.
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.
