In this chart, numbers are divided into two sections: low numbers and high numbers. Low numbers are typically from the lower half of the range of numbers while the high numbers are from the upper half of the range of numbers. Players may use these to balance their number selections to have a better chance of matching draw results.
High/Low Number
The graph below illustrates the distribution of high and low numbers over a selected period of draws. Each bar represents a single draw, with the lower portion of the bar indicating the count of low numbers (typically defined as numbers in the lower half of the number range), and the upper portion representing the count of high numbers (those in the upper half of the range). This visually compare the frequency and balance of high versus low numbers across multiple draws. The chart provides a clear view of both individual and cumulative trends, helping to identify patterns or biases in number distribution over time.
High/Low Number Summary
Below is a summary of the high-low number distribution which groups the draws based on the specific combinations of high and low numbers (e.g., 3 high and 2 low, 4 low and 1 high, etc.). This summary helps to highlight the most common high-low patterns observed over the selected period. This visually represent the distribution offering an at-a-glance view of the proportion of each high-low combination. The chart makes it easy to identify dominant patterns and assess how evenly the high and low numbers are distributed across all draws.

Format Changes in EuroMillions
Since its launch in 2004, EuroMillions has undergone several format changes aimed at enhancing and keeping the game competitive. These changes have adjusted the number pool over the years.
| Period | Format | Bonus Ball |
|---|---|---|
| February 2004 | 5 numbers out of 50 | 2 lucky stars out of 9 |
| May 10, 2011 | 5 numbers out of 50 | 2 lucky stars out of 11 |
| September 2016 | 5 numbers out of 50 | 2 lucky stars out of 12 |
The first major change occurred in 2011 when the Lucky Star pool increased from 9 to 11, making it more challenging to hit the jackpot. In 2016, the Lucky Stars increased again to 12.
How EuroMillions 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 2/9 lucky star format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 2/11 and 2/12 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.
