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. The chart covers 75 draws, from May. 23, 2025 to Sep. 30, 2025 .
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 UK Thunderball
Since its launch in June 1999, the UK Thunderball lottery has undergone several key format changes aimed at enhancing the game and increasing player excitement. These adjustments have expanded the number selection pool.
| Period | Format | Thunderball |
|---|---|---|
| June 1999 | 5 numbers out of 34 | 1 number out of 14 |
| May 9, 2010 | 5 numbers out of 39 | 1 number out of 14 |
Throughout these changes, the Thunderball number has always been drawn from its own pool of 14 numbers, separate from the main numbers, preserving the structure that has defined the game since its creation.
How Thunderball 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 5/34 number format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/39 format.
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.
