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 US Mega Millions Lottery
Since its inception in 1996, Mega Millions has undergone several changes in its number pool format, particularly in the main number set and the Mega Ball. Initially launched as “The Big Game,” the format started with selecting 5 numbers from a pool of 50 and 1 Mega Ball from a pool of 25 and expanded its number matrix several times in 2005, 2013, and 2017. in April 2025, the format was revised again, maintaining the 5/70 for the main numbers but slightly reducing the Mega Ball pool from 1/25 to 1/24. These adjustments over time have been aimed at balancing jackpot size, odds of winning, and overall game excitement.
| Period | Format | Mega Ball |
|---|---|---|
| September 6, 1996 – Launch as “The Big Game” | 5 of 50 | 1 of 25 |
| May 17, 2002 – Rebranded “The Big Game Mega Millions” | 5 of 52 | 1 of 52 |
| October 2002 – 2005 | 5 of 56 | 1 of 46 |
| October 18–22, 2013 | 5 of 75 | 1 of 15 |
| October 28–31, 2017 | 5 of 70 | 1 of 25 |
| April 8, 2025 | 5 of 70 | 1 of 24 |
How US Mega Millions 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 5/50 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/75 or 5/70 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.
