DATA METHODOLOGY
Validated records, versioned rules.
Every published draw is normalized and checked before it reaches the number tools.
Explanation updated:
Official public sources
Structured drawing records come from New York State Gaming Commission datasets. Links to the national game sites are provided for final verification.
Validation
We require a valid Eastern-time drawing date, exactly five unique white balls, a separate special ball, and values that fit the rule matrix in effect on that date.
Historical eligibility
If a selected combination could not have existed in a drawing's game matrix, that drawing is marked ineligible for the play instead of being counted as a loss.
Availability
A verified static snapshot is bundled with the site. If the newest source check fails, the last validated records remain available and are clearly marked as stale.
Historical additions and corrections
Validated refreshes may add older drawings while retaining every bundled date and its numbers, multiplier and rule era. If an official correction changes an existing outcome, the site keeps the marked snapshot until the correction is validated and included in a newly deployed snapshot. This integrity check is not a test of draw fairness.
Inspect the original sources
Dates and numbers come from these public datasets. Each game's own page describes its current rules; those rules should not be applied retroactively to every historical drawing.

Why “ineligible” is different from “no prize match”
Fixed example: 1 · 2 · 3 · 4 · 5 + Mega Ball 25. We chose this combination after knowing the rules and results to explain the boundary at 25. It is not a purchase, recommendation, prediction or strategy test.
The last drawing with 25 Mega Balls was April 4, 2025; the first with 24 was April 8. The five white balls still used the 1–70 range. Official change announcement, published March 25, 2025.
| Date | Published result | That date's ranges | Example comparison |
|---|---|---|---|
| 11 · 28 · 35 · 37 · 69 + 25 | White: 1–70 Mega Ball: 1–25 | Eligible: 0 white matches; Mega Ball matches. | |
| 10 · 16 · 50 · 60 · 61 + 17 | White: 1–70 Mega Ball: 1–24 | Excluded: Mega Ball 25 exceeds the maximum 24. |
Across these two rows, the comparison includes 1 drawing and excludes 1. The second row is not counted as a loss: this play could not exist under those rules. The first row describes a hypothetical historical match; it does not establish a purchased ticket or a claimable prize.
The rows are calculated from the public snapshot using the tool's same eligibility and comparison engine. That snapshot records its source fetch time as ; this is not the date of a new official-source check.
- Download the snapshot used (JSON) and find drawDate records 2025-04-04 and 2025-04-08 to compare their numbers with the table.
- In the Mega Millions tool, choose “All compatible history” and enter 1 2 3 4 5 + 25. Press “Use entered numbers” to apply the entry, then “Check all eligible drawings”. Open “Why drawings were excluded”: drawings from April 8, 2025 are ineligible for ball 25. Tool totals cover the entire loaded history, not only these two rows.
