Duplicate Spelling Bees
Common “Hive” wisdom holds that each Spelling Bee puzzle is unique, and that there have been no duplicates except for one known set of identical puzzles, and two known repeat “stopgap” puzzles, as explained below. However, research confirms that there have been at least 38 exact duplicate puzzles in the history of the Spelling Bee.
Two of these repeats were duplicate “stopgap” puzzles that the NYTimes released intentionally when there had been technical difficulties with the scheduled Bees, so those are not counted in a list of unintentional duplicates. (Details on these two "stopgap" puzzles are given below.)
But there have been at least 36 other pairs of likely unintentional duplicate puzzles; that is, at least 36 times when a letter set used previously was repeated at a later date with the same center letter. (Solution sets may vary between earlier and later duplicate puzzles if, for example, a word disallowed from an earlier puzzle was accepted for a later puzzle.)
Letter sets are re-used in 70%-75% of Spelling Bee puzzles, but the selection of a different center letter yields a new puzzle (though there is, of course, overlap between the solution sets of puzzles that use the same letter sets).
While 36 may seem like a large number, these 36 duplicates comprise a very small proportion of the 2,300+ regular Spelling Bees that have been offered since the puzzle had its online début on May 9, 2018.
The latest of these duplicates occurred in April 2022; this implies that the games staff noticed the duplicates and revised the design process to prevent duplication of past puzzles.
Thanks to sbsolver.com for compiling reliable data and making it freely available.
Note: This list does not include all uses of each of the letter sets listed, only the duplicate uses. Many of these letter sets have been used in other Bee puzzles, with different center letters.

In the interim before the official puzzle for that date finally went live, a duplicate of the Spelling Bee from May 14, 2018 was temporarily released to bridge the gap.] ALORTVYCenter letter T: July 12, 2020 Center letter T: Extra Spelling Bee for April 11, 2022 *[Note from sbsolver.com: On April 11, 2022, the puzzle (TALORVY)was released with a glitch that caused it to load for many players with some or all of the answers already filled in. (These players may have been seeing their answers from July 12, 2020, a nearly identical puzzle.) Due to the ensuing confusion, a replacement puzzle was released later that morning.]
