Current Mega Millions Format
Mega Millions draws twice weekly (Tuesday and Friday evenings). Players choose 5 main numbers from 1 to 70 and 1 Mega Ball from 1 to 25. The jackpot odds are 1 in 302,575,350 — roughly 3.5 times harder to win than being struck by lightning in your lifetime (1 in ~85 million cumulative).
This format has been in effect since October 28, 2017, when the main pool expanded from 75 to 70 and the Mega Ball pool changed from 15 to 25. Any frequency analysis spanning the matrix change must account for these shifts, because numbers above 70 (which existed in the old pool) have historical draws that aren't possible in the current format.
Most Common Main Ball Numbers
Since the October 2017 matrix change through April 2026, certain main ball numbers have appeared more frequently than others. With 5 balls drawn from 70 options, each number has an expected frequency of about 7.14% per draw (5/70). Over approximately 890 draws in this period, that's roughly 64 expected appearances per number.
The numbers that tend to cluster near the top of frequency charts include several from the lower and middle ranges. However, specific rankings shift from month to month as new draws come in. Rather than listing exact numbers that will be outdated by next week, we recommend checking the live Mega Millions frequency analysis tool, which updates automatically after every draw.
Key patterns that tend to persist:
- Numbers in the 1-35 range (the lower half) collectively appear slightly more than the upper half in many samples — though this fluctuates and is within normal statistical variance.
- No individual number has maintained a frequency above 9% for extended periods since the 2017 change — deviations tend to correct over time.
- The hottest number at any given moment typically has 10-15% more appearances than average, while the coldest has 10-15% fewer.
Most Common Mega Ball Numbers
The Mega Ball is drawn from a separate pool of 1-25, so each Mega Ball has an expected frequency of 4% per draw (1/25). With ~890 draws since the 2017 change, each Mega Ball should appear about 36 times.
Because the Mega Ball pool is small (only 25 numbers), the variance is higher — some balls can appear 20-30% above or below expected without it being statistically remarkable. For current Mega Ball frequency data, check the hot & cold Mega Millions tool.
One consistent finding: the most-drawn Mega Ball numbers in any window tend to stay hot for shorter periods than main ball numbers, because the smaller pool size means reversion to the mean happens faster.
Least Common Numbers
The coldest main ball numbers are just as interesting as the hottest. In any given analysis window, you'll find a handful of numbers sitting 15-25% below the expected frequency. These are the numbers that gap analysis tracks — how long since they last appeared, and how that gap compares to their historical average.
For the Mega Ball, the least-drawn numbers in recent windows often include those that had long "hot" runs in previous periods, as their frequency reverts. This is the law of large numbers in action — over sufficient draws, all numbers converge toward their expected frequency.

Does Frequency Matter for Mega Millions?
This is the critical question, and the honest answer requires nuance:
Statistically: probably not, for prediction purposes. Mega Millions draws twice per week, yielding roughly 104 draws per year. Compare that to Pick 3, which might have 730+ draws per year in a twice-daily state. The sample size for Mega Millions is far smaller, which means frequency data is noisier and deviations from expected are more likely to be random fluctuations rather than meaningful patterns.
For number selection: yes, but not how you think. Frequency data can help you avoid the most popular numbers. If you win a shared jackpot, you split it with other winners. Research shows that many players pick "sentimental" numbers (birthdays 1-31, lucky 7, etc.), making those numbers over-represented in tickets sold. Frequency analysis can help you select less popular numbers — not to improve your odds of winning, but to improve your expected share if you do win.
The Matrix Change Factor
The 2017 matrix change is a critical consideration for anyone analyzing Mega Millions frequency data. Before October 28, 2017, the main pool was 1-75 with a Mega Ball pool of 1-15. Numbers 71-75 had hundreds of historical draws that are no longer possible.
How to handle this:
- Filter by date: Only analyze draws from the current matrix (October 2017 onward). Pre-2017 data is irrelevant for the current game format.
- Be cautious with "all-time" stats: Any frequency chart showing "all-time" Mega Millions data mixes two different game formats. It's like comparing baseball batting averages across eras with different mound heights — technically the same stat, practically a different game.
- Watch for future changes: Mega Millions periodically adjusts its matrix to reset jackpot probabilities. When this happens, historical frequency data becomes less relevant.
The frequency analysis tool on DrawAnalytics lets you set custom date ranges, so you can easily filter to the current matrix period.
Hot and Cold Mega Millions Numbers Right Now
Rather than publishing specific numbers that will be outdated by the next draw, we maintain live tracking tools that update automatically:
- Mega Millions Frequency Analysis — see every ball's frequency, positional breakdown, and pair correlations.
- Mega Millions Hot & Cold Tracker — configurable windows showing which main balls and Mega Balls are running hot or cold right now.
- New York Mega Millions Frequency — same data, localized for NY players.
These tools pull from the same draw data that feeds all 43 states on the platform. Mega Millions results are the same nationwide — the tools just present the analysis in the context of your state's tax rates, draw schedules, and other local games.
Number Selection Strategies for Mega Millions
If you use frequency data as part of your Mega Millions selection process, consider these approaches:
- Hot numbers approach: Pick the 5-10 most frequently drawn main balls and the 2-3 hottest Mega Balls from the last 6-12 months. Play combinations from this pool.
- Mixed hot/cold: Combine 3 hot main balls with 2 cold ones. The hot numbers ride recent momentum; the cold numbers offer contrarian value and are less likely to be shared if they win.
- Popularity avoidance: Check which numbers are most commonly played (not most commonly drawn). Avoid the cluster of 1-31 (birthday numbers), lucky 7, and other culturally popular picks. If you win, splitting with fewer co-winners means a bigger share.
- Wheeling: If you have 8-12 candidate numbers, use a wheeling system to cover them in optimized ticket sets.
The Odds Reality Check
No frequency analysis, hot/cold tracking, or number selection strategy changes the fundamental odds of Mega Millions: 1 in 302,575,350 for the jackpot. These tools are for entertainment and education — they help you make more informed, data-aware choices, but they don't shift the mathematical probabilities.
The expected value of a $2 Mega Millions ticket (excluding jackpots) is about $0.64, meaning the lottery returns roughly 32 cents per dollar wagered on non-jackpot prizes. When jackpots are unusually large, the overall EV increases but rarely exceeds $2 (breakeven) because of tax withholding and jackpot splitting probability.
Disclaimer: Lottery draws are random events. Past results do not predict future outcomes. Frequency analysis of Mega Millions is an educational tool, not a prediction system. The jackpot odds are 1 in 302,575,350 regardless of which numbers you choose. Please play responsibly and within your budget.
