Historical frequency analysis for every Mega Millions number — most drawn, least drawn, Mega Ball stats, and how to apply the data when selecting your picks.
Mega Millions has been drawing twice weekly since 2002, with several rule changes along the way (most significantly in 2017, when the number pool expanded from 1–75 to 1–70 for main balls and 1–15 to 1–25 for the Mega Ball). Across hundreds of drawings, every number has its own frequency profile — and those profiles are what WinLottoBig makes searchable and actionable.
This guide explains the current state of Mega Millions frequency data, what it means for number selection, and how to use the tool effectively.
Mega Millions players select 5 numbers from 1–70 (the white balls) and 1 Mega Ball from 1–25. Drawings take place every Tuesday and Friday night. Jackpot odds are approximately 1 in 302 million for matching all six numbers. The frequency data for white balls and Mega Balls must be analyzed separately, as they're drawn from different pools.
The following numbers have appeared most often across all historical Mega Millions drawings. Data reflects the full drawing history tracked by WinLottoBig — for current counts, use the live tool.
These numbers have appeared least often across the historical record. Note that many of the cold numbers are in the higher range (55–70) — this partially reflects the 2017 pool expansion, when 1–75 was reduced to 1–70. Numbers in the 55–70 range have fewer total drawings in their history.
The Mega Ball is drawn separately from a pool of 1–25. Its frequency profile is quite different from the white ball pool — and many players overlook this when selecting their bonus ball. WinLottoBig tracks Mega Ball hot and cold data independently.
In October 2017, Mega Millions changed its format significantly: the white ball pool changed from 1–75 to 1–70, and the Mega Ball pool expanded from 1–15 to 1–25. This means numbers above 70 no longer exist in the current game, and Mega Ball numbers above 15 have much shorter histories than lower Mega Ball numbers.
This is why many high-numbered white balls appear "cold" — some of them simply have fewer total drawings in the current format. A complete analysis should account for this structural break in the data series.
Pro tip: When reviewing cold numbers, check if the lower frequency partially reflects the 2017 rule change. Numbers like 67 or 65 have only been possible since 2017 (when the pool shrank from 75 to 70, they remained in range), while numbers like 30 have been drawn across the full historical record.
The simplest approach: open WinLottoBig, look at the hot and cold displays, and use the generator to create picks weighted toward whichever pool you prefer. The three modes — Hot, Cold, and Mixed — give you a pick set in seconds without manual selection.
For a more deliberate approach: review the raw frequency counts (shown under each ball), identify any numbers you already like playing, and check whether they're historically hot, cold, or mid-range. Use that context to fill in the rest of your selection from the complementary pool.
