This chart displays the statistical trends of consecutive draws, showing how the mean, standard deviation, and range of numbers drawn vary over time. This illustrate the variability and distribution patterns inherent in random lottery results.
SuperLotto Plus Charts
Mean, Standard Deviation (STDEV), and Range Trend
The chart below presents the statistical trends of SuperLotto Plus lotto combinations from Dec. 14, 2024 to Aug. 30, 2025 , covering 75 draws by tracking the mean, standard deviation, and range.
The Mean line indicates the average drawn number per draw, the Standard Deviation (STDEV) line shows how widely spread the numbers in each draw are from their respective mean, and the Range line, calculated as the difference between the highest and lowest number in each draw, shows the gap between the highest and lowest numbers drawn.
Together, these statistics and their trends offer a clearer picture of the variability inherent in lotto draws, though they do not imply predictability, as true lottery systems are designed to be random. It helps to observe whether the statistical properties of the drawn numbers exhibit any pattern, volatility, or clustering over time.
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.
