Categories From This Board That Recur
Three Habits That Crack a Red Herring Board
Count to sixteen before you group anything
Every board is three groups of four plus four red herrings. Four words are meant to be left over, and players who forget that spend their time forcing a fourth group that was never there.
Solve the narrowest theme first
One group is always more specific than the others — a named set like "Mouse, Characters" rather than a loose one like "Strong Words". Lock that group first: each correct group removes four candidates from everything else on the board.
A word that fits two groups is usually a decoy
The herrings are chosen to look plausible in more than one place. When a word could sit in two themes, that ambiguity is the tell — set it aside rather than committing it to the group it fits slightly better. Any board in the archive is practice for it.
How to Solve a Red Herring Board
The order that clears a board fastest.
Count to sixteen first
Every board is three groups of four plus four red herrings. Knowing four words are meant to be left over stops you forcing a fourth group that does not exist.
Start with the tightest theme
One group is always more specific than the others — on April 21, 2023 that was Scotch. Lock the group you are surest of, because each correct group removes four candidates from the rest.
Treat near-misses as suspects
A word that almost fits two groups is usually a herring. The puzzle is built so the decoys look plausible; plausibility is the tell, not the proof.
Verified Answers, Not Guesses
How we verify every dated board in the archive, group by group, with the red herrings kept separate
Each board is taken from the published puzzle for that date and re-checked against the source before it goes live. Notes explaining a link are kept as the source wrote them. The full routine is in our methodology, and the standards each page is held to are in the editorial policy.
