Using a Word's History Without Being Fooled By It
A high decoy rate is a warning, not a rule
Rock has been a red herring on 27% of its appearances. That makes it worth leaving until last, not worth discarding — the board decides, and the three-group structure is what settles it.
Themes repeat, words move between them
This word has sat in 13 different themes. A returning theme brings different members with it, which is why the category pages show every word a theme has ever used rather than a fixed four.
Count to sixteen first
Three groups of four plus four herrings. Four words are meant to be left over, and expecting that is what stops you forcing a fourth group that was never there.

Count to sixteen first
Three groups of four plus four red herrings. Four words are meant to be left over — see any board in the archive.
Lock the tightest theme
Solve the most specific group first; each correct group removes four candidates from everything else.
Distrust the near-miss
A word that almost fits two groups is usually a decoy — which is exactly what a page like this one records.
Verified Answers, Not Guesses
How we verify every board Rock has appeared on, and whether it was an answer or a decoy each time
Word histories are built from the 3,529 dated boards in our archive rather than from any published list — the source has no word pages. Each appearance links to the board it came from so it can be checked. The routine is in our methodology and the standards in our editorial policy.
