How big are the gaps between Mega Millions numbers?
Mega Millions has been drawn as 5 numbers from 70 plus a Mega Ball from 24 since April 2025. Everything on this page counts only the 158 draws since that change.
Sort a Mega Millions draw and the commonest distance between neighbouring numbers is 1: 6.6% of all gaps, where chance predicts 7.1%.
5 numbers leave 4 gaps, and across 158 draws that is 632 of them. Chance points at the same size: small gaps are the most numerous because there are more ways to fit the rest of the draw around them. The widest gap of a draw has averaged 24.06 against a predicted 24.10, the narrowest 3.61 against 3.36.
What was measured 4 gaps per draw
Put a draw in order and measure each step from one number to the next. A draw holding 070820 has gaps of 1 and 12. Two numbers side by side give a gap of 1, which is the smallest a gap can be.
Every predicted figure here is computed from each draw's own pool and then added up. A gap of 45 only exists once the pool is large enough to hold it, so a single history wide rate would print a shortfall at every wide gap that is an artefact of the pool, not of the draws. This game has drawn from one pool of 70 numbers throughout, so the per draw sum and a single rate agree, and the sum is kept because it stays right if the pool ever changes.

SE is the gap between seen and predicted divided by one standard error. The last row bundles every gap of 13 and above, so it is large by construction and does not compete with the single sizes above it. Thirteen rows are read here and none of them sits outside the range ordinary variation produces.
Recent trend last 100 draws, then blocks of 20
result for the blockrange ordinary variation allowsoutside that range
Each point is one block of 20 draws: the average widest gap in that block. The band is what chance predicts for those draws, computed from their own pools, which is why it is not a flat line. A point outside the band is marked.
