Updated 2026-10-30.
One player reports the updated English rules allow it; other players disagree.
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.
The publisher's rules contact confirmed names are allowed if they are one word.
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).
The publisher's one-word statement conflicts with a reported newer rulebook example; no direct ruling on two-word names.
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.
Several players read it as two words; no official ruling.
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.
The rulebook explicitly lists acronyms as words.
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.
The rulebook's special-character example covers $; drawings are the community's reading.
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.
One table ruling against some disagreement; no official ruling.
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.
The publisher's rules contact answered directly that he would accept it if everyone agrees.
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.
The publisher's rules contact ruled on these examples directly.
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.
Several players agree the marks are not allowed; the rulebook only says one word.
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.
Repliers read the rules as permitting it; no official ruling.
Yes, technically — nothing forbids it, but it rarely helps because nearly all mystery words are nouns.
One reply reads the rulebook's intent this way; no official ruling.
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.
The rulebook lists invented words as invalid clues.
No — invented words are invalid clues, and Antimonday is not a real word.
Several players agree and the rulebook bans only invented words.
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.
The rulebook lists written-differently words as invalid and says spelling mistakes count as identical.
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.
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.
Several players agree it fits the rulebook's wording; no official ruling.
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.
Repliers agree; no official ruling.
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.
The rulebook says players choose without coordinating.
No — clues must be chosen without coordinating, and assigning roles removes the challenge.
The publisher ruled on spork and the rulebook gives the prince and princess example.
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.
The rulebook bans same-family words and players agree Chewy counts as sharing the root.
No — it shares a root with the mystery word, so it is the same family and invalid.
The publisher confirmed that same meaning with a different word is fine.
Yes — different words with the same meaning are allowed; only words sharing a root or word parts are forbidden.
Two community posters agree; the rulebook's family rule supports it.
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.
Players disagree and there is no ruling.
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.
Most repliers say yes; the rulebook does not address loanwords.
Usually yes if the word is a genuine part of the clue-giver's language; a direct translation is not allowed.
Repliers agree; no ruling.
Usually yes — it is a specific variety, not a direct translation, so it is not the banned foreign-language version of the word.
Two players agree and the rulebook sets the one-word rule.
A one-word brand is fine; a multi-word brand breaks the one-word rule, though an acronym such as VS is allowed.
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.
The rulebook says identical clues are cancelled.
Yes — every copy is cancelled, whether two players or five wrote the word, so the guesser sees none of them.
The rulebook says plurals, gender and same-family variants are identical; players apply this to tenses and adjective or adverb forms.
Yes — verb tenses, singular and plural, gender and adjective or adverb forms count as the same word, so they cancel (string and strung).
Several players agree on these pairs; a few dissent.
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.
Repliers agree; no ruling.
Mostly no — a verb and an adjective are treated as different words, while behead and beheaded would cancel.
Unsettled. Two players would cancel them as the same clue; one says a symbol differs from the word.
The rulebook states this explicitly.
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.
This follows from the rulebook's guess and final-turn rules.
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.
The publisher said the rulebook's same-pronunciation rule is a translation problem.
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.
The publisher's rules contact answered this directly.
No — the publisher's ruling is that it is a different word, though a table may choose to accept it.
The publisher states his own practice rather than a ruling; other players mostly agree, with one dissent.
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.
One reply says no and one would accept it; no ruling, though the publisher treats same-family words as different guesses.
No — it is a different word, so it is not correct.
The rulebook gives no time limit; table customs are community practice.
No — the rulebook sets none. Tables vary, from about 20 seconds to a minute or two before passing.
Several players report playing larger groups; no official limit stated.
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.
