Number Frequency
The Number Frequency Statistics table below presents key metrics for analyzing the occurrence patterns of specific numbers. It covers 75 draws, from Oct. 18, 2025 to Apr. 8, 2026 .
It includes columns for Frequency, Last Draw Interval, and the Last Draw Date, which indicates the number of draws a ball appears, the number of draws since the ball last appeared, and the date the ball last appeared, respectively.

Number Frequency by Rank
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 US Powerball Lottery
Since its inception on April 22, 1992, the U.S. Powerball has undergone several significant changes in format and structure. At launch, Powerball became the first lottery game to use a dual-drum format—drawing five white balls from one set and one red Powerball from another—designed to create more prize tiers. Initially, players selected 5 numbers from 45 white balls and 1 from 45 Powerballs.
In November 1997, the format changed to 5/49 + 1/42. This was followed by another change in October 2002, expanding the white ball pool to 53 while keeping the Powerball at 42. By August 2005, the white balls increased again to 55. A major change occurred in January 2009, with the matrix becoming 5/59 + 1/39. Around this time, Florida joined the game, and the drawings were moved there.
One of the most notable changes came in January 2012 when the Powerball pool was reduced to 35, while the white balls remained at 59. Another significant format change was introduced in October 2015, adjusting the matrix to 5/69 + 1/26. This increased the odds of winning smaller prizes while making the jackpot harder to win, with overall odds shifting to approximately 1 in 292 million.
| Period | Format | Powerball |
|---|---|---|
| April 1992 | 5 of 45 | 1 of 45 |
| November 1997 | 5 of 49 | 1 of 42 |
| October 2002 | 5 of 53 | 1 of 42 |
| August 2005 | 5 of 55 | 1 of 42 |
| January 2009 | 5 of 59 | 1 of 39 |
| January 2012 | 5 of 59 | 1 of 35 |
| October 2015 | 5 of 69 | 1 of 26 |
How US Powerball 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 frequently in the 5/49 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/69 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.
