Box Plot of Lotto Draw Results Over Time
The chart below displays the statistical distribution, spread, or variability of winning SuperLotto Plus numbers from Dec. 14, 2024 to Aug. 30, 2025 , across 75 draws over time.
Each box represents the middle 50% of numbers (from the first quartile to the third quartile), while the line inside the box marks the median winning number for that period. The “whiskers” extend to the minimum and maximum numbers drawn, and any points outside these whiskers indicate unusually low or high results relative to other draws. By tracking how the quartiles and range shift over time, the chart provides insight into the variability and spread of winning numbers, which can be used to visually assess the randomness and consistency of lotto draws.
Quartile and Range Characteristics
The table below presents the statistical characteristics of each lotto draw with range, skewness, and spread. The range measures the gap between the lowest and highest numbers. Skewness indicates whether the numbers are concentrated toward the lower or higher end of the pool, helping to identify directional bias in the draw. The IQR (Interquartile Range) shows how widely the numbers are spread or distributed within the middle 50% of results, and clustering highlights whether certain numbers tend to appear close together within the same draw. Together, these metrics provide a deeper view of the draw’s randomness and number distribution patterns.

Format Changes in California's SuperLotto
Since its inception in 1986, California SuperLotto has undergone several significant format changes that have impacted the odds of winning the jackpot. Here’s a clear timeline of the California SuperLotto Plus format changes since its inception:
| Period | Format | Mega Ball |
|---|---|---|
| October 18, 1986 | 6 numbers out of 49 | none. |
| June 30, 1990 | 6 numbers out of 53 | none. |
| April 29, 2000 | 5 numbers out of 47 | 1 number out of 27 |
Initially, the game followed a 6/49 format, where players selected six numbers from a pool of 49, offering odds of about 1 in 13.98 million. In 1990, the format was modified to 6/53, making it slightly more difficult to win. The most substantial change occurred in 2000 when the game was rebranded as SuperLotto Plus. The new format required players to choose five numbers from 1 to 47 and a separate Mega number from 1 to 27, shifting to a two-drum system. This overhaul increased the jackpot odds to approximately 1 in 41 million.
How California SuperLotto Plus 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 5/47 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 6/49 or 6/53 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.
