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.

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.
