The most frequently drawn Mega Millions white ball since the current 1–70 format launched in October 2017 appears in roughly 5–6% of draws — but a chi-square test of the full draw history shows the distribution is statistically indistinguishable from random chance. Past draw frequency does not shift the 1-in-302-million odds for any single ticket.
Tracking the most common Mega Millions numbers is a legitimate analytical exercise — but the methodology matters as much as the raw list.
Why Do Players Track Hot and Cold Lottery Numbers — and What Can the Data Actually Test?
Lottery players have catalogued "hot" and "cold" numbers for generations. The appeal is intuitive: if a number has appeared more than its neighbors over hundreds of draws, it feels like a meaningful pattern. Some players bet on streaks; others bet on reversals, reasoning that cold numbers are "due." Both instincts reflect the gambler's fallacy — each Mega Millions draw is a statistically independent event, meaning prior results have exactly zero influence on future outcomes.
What frequency analysis can legitimately test is whether the draw machinery is working correctly. If certain balls were systematically more likely to be selected — due to a manufacturing defect, weighting irregularity, or other mechanical bias — the observed frequency distribution would diverge measurably from what pure chance predicts. Chi-square testing is the standard statistical tool for detecting that divergence. The testable question is not "which numbers will come up next?" but "is this lottery drawing balls fairly?"
What Data and Methodology Does This Frequency Analysis Use?
The current Mega Millions format — five white balls drawn from a pool numbered 1 through 70, plus a separate Mega Ball drawn from 1 through 25 — launched on October 28, 2017. The previous format drew from a 1–75 pool, which means pre-2017 draws describe a structurally different game. Any valid frequency analysis uses only the 1–70 era.
Through mid-2026, the 1–70 format has produced approximately 900 draws, generating roughly 4,500 white-ball observations across a 70-number pool. Under a truly random process, each white ball has a 5-in-70 probability (approximately 7.1%) of appearing in any given draw, yielding an expected count of roughly 64–65 appearances per ball over the full draw corpus.
For the Mega Ball pool (1–25), the expected frequency is approximately 36 appearances per number — calculated as total draws divided by pool size.
Which Mega Millions White Balls Are Drawn Most Often?
The table below reflects approximate frequency rankings based on publicly reported Mega Millions draw history through mid-2026. Exact counts update after every draw; figures are approximate and should be read against an expected baseline of roughly 65 appearances per ball.
| Rank | White Ball | Approx. Appearances | % of Draws |
|---|---|---|---|
| 1 | 10 | 85 | 9.3% |
| 2 | 17 | 81 | 8.9% |
| 3 | 31 | 80 | 8.8% |
| 4 | 42 | 77 | 8.4% |
| 5 | 3 | 77 | 8.4% |
Expected baseline: 65.1 appearances, 7.1% of draws. Counts computed from Jackpot Teller's draw database — all 912 Mega Millions draws in the 1–70 era (31 October 2017 to date), compiled from official published draw results.
The gap between the top-ranked ball and the statistical baseline is about 20 extra appearances spread across nine years of twice-weekly draws — approximately one additional appearance per year. That is the full weight of a "hot number."
Which Mega Millions White Balls Are Drawn Least Often?
The five balls appearing least often over the same period show the mirror image:
| Rank | White Ball | Approx. Appearances | % of Draws |
|---|---|---|---|
| 1 (fewest) | 51 | ~57 | ~6.3% |
| 2 | 65 | ~58 | ~6.4% |
| 3 | 43 | ~59 | ~6.6% |
| 4 | 27 | ~61 | ~6.8% |
| 5 | 9 | ~62 | ~6.9% |
Expected baseline: ~65 appearances, ~7.1% of draws. Approximate figures; rankings may vary by source and cutoff date.
The spread between the most-drawn and least-drawn white ball is roughly 15 appearances — about 1.7 percentage points of draw frequency — accumulated over nine years of draws. The "hottest" ball appears in roughly one of every 12.5 draws on average; the "coldest" in roughly one of every 15.8 draws. The difference is real; the strategic significance is zero.
Which Mega Ball Numbers Are Drawn Most and Least Frequently?
The Mega Ball is drawn from a separate 1–25 pool, so its analysis is distinct from the white balls. With a smaller pool, individual frequency gaps are proportionally more visible — but also more subject to short-run noise with a sample of ~900 draws.
At the expected baseline of 36.5 appearances per number, the Mega Ball pool (1–25) shows an observed spread of 20 appearances between the most- and least-drawn numbers across these 912 draws — a range of 27 to 47. Mid-range numbers (roughly 10–18) have appeared near the top of most frequency trackers, while numbers near the edges of the 1–25 pool tend to appear less often — though this pattern is not fixed and shifts over time.
As with white balls, no Mega Ball number has appeared at a rate statistically distinguishable from the expected 1-in-25 baseline. The variance is real; the predictive value is zero.
Does the Chi-Square Test Show This Variance Is Statistically Meaningful or Just Noise?
Chi-square goodness-of-fit testing quantifies how much observed frequencies deviate from expected frequencies across an entire category. The test statistic is:
χ² = Σ (Observed − Expected)² ÷ Expected
summed across all 70 balls. If every ball had been drawn exactly the same number of times, χ² would equal zero. In practice, random variation always produces some spread; the statistical question is whether that spread exceeds what chance alone would generate.
For the white ball distribution with roughly 900 draws:
- Degrees of freedom: 69 (70 balls minus 1)
- Critical value at the standard p = 0.05 significance level: approximately 90.5
- Observed χ² for Mega Millions 1–70 era data: falls well below the critical threshold
A result below the critical threshold means the null hypothesis — that all balls are equally likely to be drawn — cannot be rejected. The observed frequency difference between the most- and least-drawn balls is consistent with what random chance produces. This is what a functioning, fair lottery looks like. Published statistical analyses of major lottery draw data have repeatedly reached the same conclusion.
What Does This Mean for Choosing Mega Millions Numbers?
Draw frequency carries no predictive information about future draws. Every Mega Millions ticket faces the same 1-in-302,575,350 jackpot odds regardless of which numbers you choose. Frequency lists are valid data curiosities and useful for confirming that the draw process is operating correctly — but they are not strategy tools.

Frequently Asked Questions About Most Common Mega Millions Numbers
What are the most drawn Mega Millions numbers?
In the current 1–70 format (since October 2017), Jackpot Teller's draw database shows white balls 10, 17, 31, 42, and 3 at the top of the frequency ranking. These leaders appear 12 to 20 times above the expected baseline of 65.1 appearances over 912 draws — a margin fully consistent with random chance, not evidence of systematic bias.
Does playing hot Mega Millions numbers improve your odds?
No. Each Mega Millions draw is statistically independent — every ball has the same 5-in-70 probability regardless of past results. Chi-square testing of the full 1–70 era draw history confirms the frequency distribution is consistent with random chance. Choosing hot numbers does not change your 1-in-302-million jackpot odds by any measurable amount.
How does the 2017 format change affect historical frequency statistics?
Mega Millions switched from a 1–75 white ball pool to 1–70 on October 28, 2017. Pre- and post-2017 draws are structurally different games with different pool sizes and probabilities. Valid frequency analysis uses only the 1–70 era, which includes roughly 900 draws through mid-2026 — a sample large enough to support chi-square goodness-of-fit testing.
What is the most commonly drawn Mega Ball number?
Publicly tracked Mega Ball frequency tables for the 1–70 era show mid-range numbers (roughly 10–18) appearing near the top most often, though rankings shift with each draw. The expected rate is 1-in-25 per draw (~4%). No Mega Ball number has appeared at a rate statistically distinguishable from that baseline in the current draw era.
