Frequency, draw history and statistical context for the number 66 across all historical Mega Millions draws.
Across 1,000 historical Mega Millions draws, the number 66 has appeared 78 times — that's 7.80% of all draws. That's 9% above the expected rate for a uniformly random draw, putting it firmly in the hot bucket.
Number 66 was last drawn in the latest draw. Whether that makes it "due" is a long-running debate among lottery players — the mathematical answer is that lottery draws are independent events, so a number's history has no influence on the next draw. But the Strategy Lab lets you bias your picks toward or away from overdue numbers if you want to play with that pattern.
