This chart shows the distribution of odd and even numbers over a series of draws to spot number biases. Players may use these to balance their number selections to have a better chance of matching draw results
Odd/Even Number
The chart below visually represents the distribution of odd and even numbers over a selected range of draws. Each bar corresponds to a specific draw, and it is divided into two segments: the lower segment represents the count of odd numbers drawn, while the upper segment shows the count of even numbers. This makes it easy to compare the proportion of odd and even numbers within each draw, as well as observe any trends or imbalances over time. The total height of each bar indicates the total number of numbers drawn per draw.
Odd/Even Number Summary
This summary categorizes each draw by how many odd and even numbers it contains, making it easy to identify the most common distribution patterns across all draws in the selected period. To complement this data, a donut pie chart visually represents these groupings, with each slice corresponding to a specific odd-even combination. The size of each slice reflects its relative frequency, offering a quick overview of how often each odd-even balance occurs.

Format Changes in UK Lotto
The UK National Lottery's Lotto game has undergone several significant format changes since its launch in 1994, all aimed at keeping the game fresh, exciting, and capable of generating larger jackpots. See the table below.
| Period | Format | Bonus Ball |
|---|---|---|
| June 1999 | 6 numbers out of 49 | 1 from the same number pool |
| October 2015 | 6 numbers out of 59 | 1 from the same number pool |
How UK 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 6/49 number format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 6/59 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.
