This chart shows the frequency of numbers being drawn over a period of time. Hot Numbers are frequently drawn recently and Cold Numbers have not been drawn as often.
Heat Maps
The chart below visually represents the frequency with which each number has been drawn over a specific period. In this heat map, colors indicate how often each number appears, with deep red representing the most frequently drawn numbers and dark blue indicating the least frequent. Warmer colors show moderately high frequencies, while cooler tones represent less common numbers. This color-coded system allows viewers to quickly identify "hot" numbers—those that appear more often—and "cold" numbers—those that are rarely drawn—making it a useful tool for analyzing patterns or trends in lottery results.

Hot and Cold Numbers
"Hot" and "Cold" numbers refer to how often certain numbers are drawn over time. Hot numbers are those that appear most frequently in recent draws and are often highlighted in dark red on a heat map. These numbers are believed by some players to have a higher chance of appearing again due to their repeated occurrences. On the other hand, cold numbers are those that have been drawn the least often and are shown in dark blue on the heat map. Moreover, the "consecutive draw" column typically refers to how many consecutive draws (lotto results) a specific number has appeared in. It's a measure of how "hot" or persistent a number is over recent draws.

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.
