What the archive shows
Mega Millions white ball 66 is tracked here on the current matrix: 5 white balls from 1 through 70, from October 31, 2017 through November 10, 2026. Drawings outside that window are in the full NY Open Data file, and they are reported separately because they used a different field.
In these 943 drawings it appeared 75 times. That is 7.6 appearances above the even-split count of 67.4. An even split gives every white ball the same share of those drawings, because five white balls are drawn from the field each time. The median count in this pool of 70 is 67.0. Mega Millions white ball 66 ranks 10th, tied with 1 other number.
The last appearance was October 13, 2026, which is 8 drawings ago. That gap ranks 31st longest in the pool, tied with 3 other numbers. The longest miss lasted 53 drawings, after May 14, 2019 and before it returned on November 19, 2019.
The appearance before the latest one was September 8, 2026, 10 drawings earlier. Across every pair of successive hits, the average distance is 12.3 drawings, and that average includes the drawing that brought the number back.
Among complete calendar years in this set (2018–2025), 2024 had the most appearances, 15. 2020 and 2025 each had the fewest, 5. In the latest 100 drawings of this set it appeared 9 times, and in the latest 25 it appeared 2 times. Those windows are a recent stretch of drawings already held.
The most recent line was October 13, 2026: white balls 11, 12, 15, 40, 66, and Mega Ball 17.
When Mega Millions white ball 66 was drawn, the other white balls beside it most often were white ball 30 (9 times), white ball 10 (8 times), and white ball 14 (8 times). A pair that leads this list is a pair that happened. The next drawing still takes five white balls from the full field.
The Mega Ball values in those same drawings were led by Mega Ball 11 (6 times), Mega Ball 15 (6 times), and Mega Ball 22 (6 times).
The neighboring white balls in this same set: white ball 65 (54 appearances) and white ball 67 (54 appearances). Neighbors are next to each other on the number line only. They are separate balls in the machine.
The full file holds 2,556 drawings and records 106 appearances of Mega Millions white ball 66. The earliest of them is February 25, 2014. The full-file count mixes older matrices, so it is the wrong denominator for a current-game rate. Use the matrix count above for that comparison.
A gap of 8 drawings leaves the odds unchanged. Each current Mega Millions white ball has a 5-in-70 chance on the next drawing. The hot, cold, and overdue guide and the odds guide explain that at more length. This page is a record of the archive fetched November 12, 2026.
