Choosing clues

Is a hyphenated word like Spider-Man a legal clue?

One player reports the updated English rules allow it; other players disagree.

  • mitcharf · Community · 2022-11-01
  • Robrun · Community · 2019-07-01
  • archit3uthis · Community · 2019-12-02
  • Huuuze · Community · 2019-05-26disagrees
  • freddb · Community · 2019-10-14disagrees

Yes in practice. A hyphenated word that is normally written that way (Spider-Man) is generally treated as one word, and one player reports that the updated English rules say so explicitly. Older readings counted the hyphen as a second word, and some tables still reject clues like death-stick.

Are proper nouns like names and places legal clues?

The publisher's rules contact confirmed names are allowed if they are one word.

  • Stefan RPROD · Publisher · 2024-02-05
  • Uthred · Community · 2018-12-04
  • vnlima · Community · 2019-06-04
  • enemyoftheworld · Community · 2024-03-20
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

Yes — a proper noun is fine as long as it is a single word and does not share a root with the mystery word (Potter, York, Ikea).

Is a two-word name like Red Bull or Niagara Falls a legal clue?

The publisher's one-word statement conflicts with a reported newer rulebook example; no direct ruling on two-word names.

  • Stefan RPROD · Publisher · 2024-02-05
  • Waltex · Community · 2026-05-25
  • Tronin · Community · 2026-05-25
  • cferejohn · Community · 2026-04-08disagrees

Unsettled. The publisher's statement is that a name must be one word, which rules out two-word names, but the newer rulebook reportedly lists Red Bull as an example of a valid proper noun. The stricter one-word reading is better supported, though many tables accept well-known multi-word names.

Is a number with a unit, like 1000 kg or 37 inches, a legal clue?

Several players read it as two words; no official ruling.

  • msaari · Community · 2020-12-10
  • msaari · Community · 2020-12-10
  • msaari · Community · 2024-03-18
  • qwertymartin · Community · 2024-03-18
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

Probably not. A number and unit written with a space is two words, and spelling it out does not fix that. A single digit string such as 007 is explicitly allowed by the rulebook.

Are acronyms legal clues?

The rulebook explicitly lists acronyms as words.

  • Just One rulebook · Rulebook · 2. CLUE SELECTION
  • negatrev · Community · 2023-07-23
  • negatrev · Community · 2023-07-23
  • niraD · Community · 2022-11-02
  • DuncanYoudaho · Community · 2022-11-01

Yes — the rulebook counts an acronym as a word. A true acronym pronounced as a word (scuba, laser) stands on its own, while plain abbreviations like TMNT are a looser case that some tables debate.

Are symbols or punctuation like $ or ? allowed as clues?

The rulebook's special-character example covers $; drawings are the community's reading.

  • Just One rulebook · Rulebook · 2. CLUE SELECTION
  • Tronin · Community · 2024-03-17
  • NickDanger42 · Community · 2024-03-17
  • tool · Community · 2019-04-02
  • Stefan RPROD · Publisher · 2019-04-02disagrees

Yes for keyboard characters — the rulebook counts special characters as words and uses $ for America as an example. Drawings, logos and other non-keyboard symbols are not words, though some groups allow them.

Can a symbol be combined with a number, like $3?

One table ruling against some disagreement; no official ruling.

  • crazybirdman · Community · 2022-11-24
  • Erick864 · Community · 2022-11-26disagrees

Unsettled. Symbols and numbers are each fine alone, but one table ruled $3 illegal as two things, while another player argues a decimal point is part of the number.

Is a word with a superscript symbol like Clue(TM) allowed as a clue?

The publisher's rules contact answered directly that he would accept it if everyone agrees.

  • Stefan RPROD · Publisher · 2021-10-15
  • vnlima · Community · 2021-10-21disagrees
  • archit3uthis · Community · 2021-10-21disagrees

Yes if your table agrees — the publisher's rules contact says the rules are open and he would accept it. Some groups reject mixing a word with a symbol, such as -fighter.

Are prefixes like bi, re or tri legal clues?

The publisher's rules contact ruled on these examples directly.

  • Stefan RPROD · Publisher · 2020-06-15
  • SuperGLS · Community · 2020-06-07
  • steckman · Community · 2020-06-07disagrees

Yes without a hyphen — the publisher's rules contact says Bi, Re and Tri are fine (though he was unsure about English), but Bi-, Re- and Tri- are not allowed because of the hyphen.

Can a clue use a hyphen, ellipsis, underscore or brackets to show a word comes before or after the mystery word, like ...ball or -thrower?

Several players agree the marks are not allowed; the rulebook only says one word.

  • Dark_Mirror · Community · 2020-12-24
  • Dark_Mirror · Community · 2020-12-24
  • Dark_Mirror · Community · 2021-06-27
  • Dark_Mirror · Community · 2026-01-01
  • cferejohn · Community · 2026-01-01
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

No — write the bare word and let the guesser infer the compound. Groups often rub out the marks before revealing; the clue is only cancelled if what remains is not a real word.

Can you use a part of speech like GERUND as a clue?

Repliers read the rules as permitting it; no official ruling.

  • msaari · Community · 2019-07-06
  • archit3uthis · Community · 2020-01-06

Yes, technically — nothing forbids it, but it rarely helps because nearly all mystery words are nouns.

Can a player write a non-clue such as a blank or ellipsis?

One reply reads the rulebook's intent this way; no official ruling.

  • GamesMad · Community · 2026-08-10
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

No — every clue has to help the guesser, so a meaningless entry is invalid. Symbols are allowed, so dots would be read as a real clue.

Is a made-up word like Antimonday a legal clue?

The rulebook lists invented words as invalid clues.

  • Just One rulebook · Rulebook · 2. CLUE SELECTION
  • GamesMad · Community · 2026-08-08
  • Gawain · Community · 2026-08-08
  • GamesMad · Community · 2026-08-08

No — invented words are invalid clues, and Antimonday is not a real word.

Are compound words written without spaces legal clues?

Several players agree and the rulebook bans only invented words.

  • msaari · Community · 2025-06-20
  • Berthold · Community · 2025-06-20
  • msaari · Community · 2025-06-20
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

Yes if the compound occurs naturally in the language (blackboard, German or Finnish compounds); invented compounds are not allowed. Names written without a space are up to the group.

Are accidental misspellings of a clue still allowed?

The rulebook lists written-differently words as invalid and says spelling mistakes count as identical.

  • Just One rulebook · Rulebook · 3. COMPARING CLUES
  • Uthred · Community · 2018-12-04

Yes — accidental misspelling is fine, and for cancelling purposes spelling mistakes do not make clues different. A deliberate misspelling to add information is against the rules, such as Shurt for Shirt.

Is a homophone of the answer, like Night for Knight, a legal clue?

Two players allow it, but the rulebook example (Whether for Weather) points the other way; no direct ruling.

  • cferejohn · Community · 2026-10-19
  • iNano78 · Community · 2026-10-19

Unsettled, but lean no. The rulebook bans a word phonetically identical to the mystery word with a different meaning (Whether for Weather), which is the Night for Knight case. Two replies say it is fine because the guesser cannot hear which spelling was meant, but that conflicts with the rulebook text.

Is a letter-and-number code like E1 a legal clue?

Several players agree it fits the rulebook's wording; no official ruling.

  • pinoeppel · Community · 2026-03-29
  • Stefan B · Community · 2026-03-30
  • russ · Community · 2026-03-29disagrees
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

Probably yes — the rulebook counts digits, acronyms and special characters as words, and players read a code like a chess square as fitting that. A minority say E1 is not a word.

Can two clues that only make sense together be used, like not and darkness for light?

Repliers agree; no official ruling.

  • qwertymartin · Community · 2023-05-28
  • archit3uthis · Community · 2023-05-28
  • qwertymartin · Community · 2023-05-28
  • Tronin · Community · 2023-05-28

No — each clue must relate to the mystery word on its own. Linked clues are fine only if each one does, so darkness works and not does not.

Can players agree beforehand who gives the obvious or category clue?

The rulebook says players choose without coordinating.

  • Just One rulebook · Rulebook · OBJECT OF THE GAME
  • qwertymartin · Community · 2022-04-28
  • MajaiofDreams · Community · 2022-04-28

No — clues must be chosen without coordinating, and assigning roles removes the challenge.

What counts as the same word family?

The publisher ruled on spork and the rulebook gives the prince and princess example.

  • Stefan RPROD · Publisher · 2020-05-02
  • Just One rulebook · Rulebook · 2. CLUE SELECTION
  • Alaena · Community · 2020-09-19
  • Eeeville · Community · 2018-12-27
  • benc · Community · 2019-12-31
  • ralpheous · Community · 2019-07-24disagrees

Words built on the same root with a different prefix or suffix (prince and princess, fishing and fisher) are one family. The publisher's rules contact says spork is not valid for spoon. Deeper etymological links like school and scholarship are not settled, and the publisher says tables can move the line.

Is a clue sharing a root with the answer, like Chewy for Chewbacca, legal?

The rulebook bans same-family words and players agree Chewy counts as sharing the root.

  • Just One rulebook · Rulebook · 2. CLUE SELECTION
  • Dark_Mirror · Community · 2020-02-19
  • lujaamko · Community · 2020-02-19
  • matttutor · Community · 2020-02-22disagrees

No — it shares a root with the mystery word, so it is the same family and invalid.

Are synonyms of the answer, like thread for string, legal clues?

The publisher confirmed that same meaning with a different word is fine.

  • Stefan RPROD · Publisher · 2019-12-02
  • Stefan RPROD · Publisher · 2019-12-02
  • Dark_Mirror · Community · 2021-06-08
  • archit3uthis · Community · 2021-06-08
  • Narlgoth · Community · 2021-09-19disagrees

Yes — different words with the same meaning are allowed; only words sharing a root or word parts are forbidden.

Is a compound containing the answer, like lovesong for song, a legal clue?

Two community posters agree; the rulebook's family rule supports it.

  • archit3uthis · Community · 2021-06-08
  • Mack O Velly · Community · 2022-11-17
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

No — it contains the mystery word, so it is the same family. The other part, such as love or bird, would be fine on its own.

Is a translation or mythological name for the answer, like Helios for sun, legal?

Players disagree and there is no ruling.

  • enemyoftheworld · Community · 2024-03-20
  • nikosmavros · Community · 2024-03-20disagrees
  • Dark_Mirror · Community · 2024-03-20disagrees

Unsettled. A direct translation is not allowed, and Helios is the modern Greek word for sun, so some reject it; others allow a one-word proper noun with no shared root.

Is a loanword in your language, like barbecue for churrasco, a legal clue?

Most repliers say yes; the rulebook does not address loanwords.

  • wyldeoak · Community · 2022-05-09
  • archit3uthis · Community · 2022-05-09
  • mazmaz · Community · 2022-05-09disagrees
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

Usually yes if the word is a genuine part of the clue-giver's language; a direct translation is not allowed.

Is a more specific foreign word, like Fettuccine for Noodle, a legal clue?

Repliers agree; no ruling.

  • msaari · Community · 2024-04-26
  • odie73 · Community · 2024-04-25
  • EvilCheesypoof · Community · 2024-04-25
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

Usually yes — it is a specific variety, not a direct translation, so it is not the banned foreign-language version of the word.

Are brand names like Pizza Hut or Victoria's Secret allowed?

Two players agree and the rulebook sets the one-word rule.

  • Tronin · Community · 2023-10-28
  • EvilCheesypoof · Community · 2023-12-27
  • Just One rulebook · Rulebook · 2. CLUE SELECTION

A one-word brand is fine; a multi-word brand breaks the one-word rule, though an acronym such as VS is allowed.

Is 1-Up a valid clue?

Repliers split on the hyphen; no ruling.

  • Erick864 · Community · 2022-10-28
  • katleman · Community · 2020-02-25disagrees

Unsettled, leaning yes. It is an established video-game term, not an invented word, but the hyphen makes it a grey area for some tables.

Comparing and cancelling clues

If several players write the same clue, are all copies removed?

The rulebook says identical clues are cancelled.

  • Just One rulebook · Rulebook · 3. COMPARING CLUES
  • Mizerak · Community · 2019-08-22
  • Laerfan · Community · 2019-08-23
  • r56ygf · Community · 2019-11-30
  • crazybirdman · Community · 2019-11-30
  • R_Guerra · Community · 2021-12-13

Yes — every copy is cancelled, whether two players or five wrote the word, so the guesser sees none of them.

Do different tenses, plurals or adjective and adverb forms of the same word cancel each other?

The rulebook says plurals, gender and same-family variants are identical; players apply this to tenses and adjective or adverb forms.

  • Just One rulebook · Rulebook · 3. COMPARING CLUES
  • Foxman9815 · Community · 2022-06-04
  • DuncanYoudaho · Community · 2022-06-05
  • klbush · Community · 2022-06-05
  • Shampoo4you · Community · 2022-06-04disagrees

Yes — verb tenses, singular and plural, gender and adjective or adverb forms count as the same word, so they cancel (string and strung).

Do pairs like Sweden and Swedish, Explosive and Unexploded, or Allergy and Allergenic cancel?

Several players agree on these pairs; a few dissent.

  • Just One rulebook · Rulebook · 3. COMPARING CLUES
  • Uthred · Community · 2018-12-04
  • DeMorcerf · Community · 2022-11-27
  • Murr · Community · 2022-11-27
  • Der Das · Community · 2022-11-27disagrees
  • qwertymartin · Community · 2020-09-17
  • bnordeng · Community · 2020-09-17
  • Viziviz · Community · 2025-04-12

Mostly yes — words of the same family cancel, though Explosive and Unexploded drew a dissent because their meanings differ. Kaboom and Boom were also called the same family.

Do behead and headless cancel each other?

Repliers agree; no ruling.

  • archit3uthis · Community · 2019-12-16
  • Drewbag84 · Community · 2019-12-17
  • jatang · Community · 2020-01-02

Mostly no — a verb and an adjective are treated as different words, while behead and beheaded would cancel.

Does $ cancel the word dollar when both are written?

Opinions split; no ruling.

  • msaari · Community · 2019-01-20
  • berz118 · Community · 2019-01-26
  • clmdvd · Community · 2019-01-19disagrees

Unsettled. Two players would cancel them as the same clue; one says a symbol differs from the word.

Guessing and scoring

Do you lose an extra card when you guess wrong?

The rulebook states this explicitly.

  • Just One rulebook · Rulebook · 4 GUESS
  • Ronaldo · Community · 2019-11-09
  • kirkroberts · Community · 2019-11-09disagrees

Yes — a wrong guess returns the current card and the top card of the deck to the box, while a skip loses only the current card.

Can you score 12 successful cards?

This follows from the rulebook's guess and final-turn rules.

  • Just One rulebook · Rulebook · 4 GUESS
  • Just One rulebook · Rulebook · END OF THE GAME
  • qwertymartin · Community · 2024-04-20
  • qwertymartin · Community · 2024-04-20

Yes — pass on one card rather than guessing wrong, since a wrong guess costs a second card. A wrong guess on the last card gives 11 because it also removes a card already won.

Is a homophone of the answer, like flour for flower, a correct guess?

The publisher said the rulebook's same-pronunciation rule is a translation problem.

  • Stefan RPROD · Publisher · 2022-11-04
  • mitcharf · Community · 2022-11-02superseded
  • Blott · Community · 2021-06-07disagrees
  • Just One rulebook · Rulebook · 4 GUESS

No, according to the publisher. The rulebook says a guess pronounced like the mystery word is valid, but the publisher's rules contact says same pronunciation is always bad and blames a translation problem. His ruling wins, though tables may keep the rulebook version.

Is a same-family word, like ballerina for ballet, a correct guess?

The publisher's rules contact answered this directly.

  • Stefan RPROD · Publisher · 2019-12-02
  • msaari · Community · 2019-11-30
  • lujaamko · Community · 2019-12-01
  • peakhope · Community · 2021-06-28disagrees

No — the publisher's ruling is that it is a different word, though a table may choose to accept it.

Is the guess correct if it is the same word in a different tense, like pining for pine?

The publisher states his own practice rather than a ruling; other players mostly agree, with one dissent.

  • Stefan RPROD · Publisher · 2022-12-21
  • bnordeng · Community · 2022-12-14
  • Murr · Community · 2022-12-14
  • Dark_Mirror · Community · 2022-12-14disagrees

Generally yes. The publisher's rules contact says he always accepts it and several tables allow it, but a strict reading of the same-family rule could reject it, so agree at your table.

Is Flint a valid guess when the mystery word is Flintstone?

One reply says no and one would accept it; no ruling, though the publisher treats same-family words as different guesses.

  • Dark_Mirror · Community · 2020-12-24
  • qwertymartin · Community · 2020-12-24disagrees

No — it is a different word, so it is not correct.

Is there a time limit for the active player to guess?

The rulebook gives no time limit; table customs are community practice.

  • Just One rulebook · Rulebook · 4 GUESS
  • archit3uthis · Community · 2020-01-08
  • JoeBoardgame · Community · 2020-01-08

No — the rulebook sets none. Tables vary, from about 20 seconds to a minute or two before passing.

Players and setup

What is the maximum number of players?

Several players report playing larger groups; no official limit stated.

  • Just One rulebook · Rulebook · CONTENTS
  • JoeBoardgame · Community · 2020-01-13
  • Rykaar · Community · 2020-03-02
  • qwertymartin · Community · 2020-01-13

Only 7 easels and markers come in the box, but groups have played with 8 to 11 by pairing players or using paper. More players make unique clues easier.
