Mega Millions is one of the two largest lottery games in the United States, with a starting jackpot of $20 million and the capacity to build into nine and even ten figures before a winner emerges. Alongside Powerball, it represents the benchmark for life-changing lottery prizes, drawing twice per week in 45 states plus DC and the US Virgin Islands.
At LottoIQ we track 930 Mega Millions draws going back to January 2013. However, Mega Millions underwent a substantial format change in October 2017 that expanded the main ball pool from 75 to 70 numbers and grew the Mega Ball pool from 15 to 25. Mixing the two eras would make every frequency count meaningless, so this analysis is restricted to the 636 draws since October 31, 2017 — the current 5/70 + Mega Ball 1–25 format. We note upfront that 636 draws is a more modest dataset than some state games — the patterns here carry less certainty than a 3,000-draw game, but they reflect the only draws that are directly comparable under today's rules.
With 636 draws and 5 balls drawn per game from a pool of 70, the expected frequency for any single number is approximately 45 appearances. These ten numbers have exceeded that baseline most consistently:
Numbers 3 and 14 lead at 58 appearances each — 29% above the statistical average of 45. What makes Mega Millions distinctly different from Powerball and Ohio Classic Lotto is the spread of its hot list. Low numbers (3, 10, 14, 17, 20, 22), a mid-range number (31, 38), and high numbers (58, 64) all appear in the top ten. This is not the low-number-dominated pattern seen in other games — Mega Millions hot numbers are distributed more evenly across the full 70-ball pool.
Despite the more balanced hot list, the cold numbers still show a tendency to cluster at the higher end of the pool:
Number 51 is the coldest in the current era with just 32 appearances — 29% below the expected average. Six of the ten coldest numbers are 45 or higher, which is consistent with the high-end cold bias seen in Powerball and other large-pool games. But there are exceptions: numbers 36, 41, and 12 are all in the mid-to-low range and have still underperformed — a reminder that with only 636 draws, individual number variance carries more weight than it would in a game with 3,000+ draws.
Powerball and Ohio Classic Lotto both show strong concentration of hot numbers at the low end of the pool. Mega Millions does not — numbers like 58 and 64 appear in its top ten alongside single-digit numbers. One possible factor is the larger main pool (70 vs 69 for Powerball, 49 for Classic Lotto) and the smaller per-number expected frequency (~45 draws), which means there is more room for high-end numbers to outperform in a 636-draw sample. With more draws over time, it will be interesting to see whether this balance holds or converges toward the low-number pattern seen in other games.
The gold Mega Ball is drawn separately from a pool of 1 to 25. Matching it is required for the jackpot and boosts prizes in every lower tier. With 636 draws and a 25-number pool, the expected frequency per Mega Ball number is about 25 appearances. The most frequently drawn Mega Ball numbers in the current era:
Number 22 leads with 34 appearances — 36% above the expected average. Numbers 11 and 24 follow at 33 and 31 respectively. The least frequently drawn Mega Ball numbers in this period are 5 (19 appearances), 8 (20), and 7 and 12 (21 each). Because the Mega Ball pool is small (only 25 numbers), individual variance is higher here than for the main ball pool — the difference between the hottest and coldest Mega Ball is 15 appearances over 636 draws, which is meaningful but should be weighted accordingly.
Pair frequency in a 636-draw dataset is more exploratory than definitive, but the following main-ball combinations have appeared together more often than chance alone would predict:
8 + 31 · 10 + 17 · 2 + 31 · 24 + 25 · 3 + 58
Number 31, which ranks third on the overall hot list, appears in two of the five top pairs (with 8 and with 2). The pair 3 + 58 is particularly notable because it combines the hottest main-ball number (3) with one of the few high-range numbers (58) that also cracked the hot list — suggesting those two numbers have shown an affinity for appearing in the same draw.
The October 2017 format change was one of the most significant structural changes in Mega Millions history. Understanding it is essential for reading any historical frequency data correctly:
Many players treat Mega Millions and Powerball as interchangeable — both are national jackpot games with similar prize structures. But there are meaningful differences worth knowing:
Mega Millions is operated by a consortium of state lotteries and is available in 45 states, Washington D.C., the US Virgin Islands, and (for online purchases) certain US territories. Players choose 5 numbers from 1 to 70 and one Mega Ball from 1 to 25. All five main numbers plus the Mega Ball must match to win the jackpot, with odds of 1 in 302,575,350. The jackpot starts at $20 million and escalates until won. Draws take place Tuesday and Friday evenings. Prizes are available as a 30-year annuity or as a lump-sum cash value worth roughly 60% of the advertised jackpot. The optional Megaplier add-on ($1 extra) multiplies all non-jackpot prizes by 2×, 3×, 4×, or 5×.
Mega Millions draws take place every Tuesday and Friday at 11:00 PM ET. LottoIQ pulls official Mega Millions draw results and updates frequency data, trend charts, and data-driven picks automatically after each draw.
