What the archive shows
Mega Ball 21 is tracked here on the current matrix: the current Mega Ball field of 1 through 24, from April 8, 2025 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 167 drawings it appeared 5 times. That is 2.0 appearances below the even-split count of 7.0. An even split gives every special ball the same share of those drawings, because one special ball is drawn each time. The median count in this pool of 24 is 7.0. Mega Ball 21 ranks 18th, tied with 2 other numbers.
The last appearance was August 4, 2026, which is 28 drawings ago. That gap ranks 9th longest in the pool. The longest miss lasted 51 drawings, after February 3, 2026 and before it returned on August 4, 2026.
The appearance before the latest one was February 3, 2026, 52 drawings earlier. Across every pair of successive hits, the average distance is 24.3 drawings, and that average includes the drawing that brought the number back.
This set does not contain a complete calendar year, so a busiest-year label would overread a partial season. The raw yearly counts are 3 appearances in 2025 and 2 appearances in 2026. In the latest 100 drawings of this set it appeared 3 times, and in the latest 25 it appeared 0 times. Those windows are a recent stretch of drawings already held.
The most recent line was August 4, 2026: white balls 14, 21, 51, 55, 65, and Mega Ball 21.
The white balls drawn most often in the same drawing as Mega Ball 21 were white ball 4 (once), white ball 5 (once), and white ball 11 (once). Those are companions in the archive, not a combination the game prefers.
The neighboring special balls in this same set: Mega Ball 20 (4 appearances) and Mega Ball 22 (7 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 66 appearances of Mega Ball 21. The earliest of them is September 10, 2002. 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 28 drawings leaves the odds unchanged. Each current Mega Ball has a 1-in-24 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.
