A NOTE FROM HISTORICAL RECORDS
Why aren't all 1,284 victories listed below?
The Hall began transitioning its historical files to a searchable digital registry in 2026. Previously certified championship results remain valid regardless of whether their individual documentation has been digitized.
The absence of an individual report from the online archive must not be mistaken for the absence of a victory. The Committee considers the certified historical totals complete and accurate.
STATEMENT HR–2026–01 · OFFICE OF HISTORICAL RECORDSPUBLIC DIGITAL REGISTRY
Recently digitized match reports.
There are no results to display.
Either no match has been certified, or the specified records do not exist within the requested classification.
OFFICIAL GLOBAL STANDINGS

The Hall maintains strict eligibility criteria for the world rankings. These requirements are presently under review.
Eligibility reviews are ongoing. No changes to the top ranking are anticipated.
ARTICLE VII · SECTION 4
The facts may be settled.
The classification may not be.
The Committee recognizes that a competitor may win a game of UNO fair and square. This, on its own, is not evidence of a championship victory.
Sanctioned World Championship status may be granted before, during, or immediately prior to the final card of a match. Designation may be issued by telephone, without prior notice to the other participants.
