One Detail Off is a printed word-deduction game for exactly four people. Three players receive the same secret word or phrase, while one receives a related but different word. Nobody is told their role. The task is to give a useful clue, listen for a mismatch, and vote before anyone reveals their word.
This guide covers the fixed twelve-round edition. It is a recreational game for people comfortable reading the English words and keeping a secret word private. The suggested age is 13+, not a human-tested rating. Digital rule checks and simulations do not establish that every group will enjoy the word pairs or finish in a particular time.
Print a small first session
Choose the A4 or US Letter edition that matches your paper. Use portrait, single-sided printing at 100% or Actual Size. Both sizes contain the same game; they are print choices, not separate packs of rounds.
For rounds 1-4, print Players pages 1, 2, 3, 6, 9 and 12: six sheets. Pages 1-2 belong in the middle of the table. Give page 3 only to Seat A, page 6 only to Seat B, page 9 only to Seat C, and page 12 only to Seat D. Each person also needs a pencil and spare paper for a private vote and for covering unused word panels.
The complete twelve-round edition uses fourteen player sheets. Seat A uses pages 3-5; B uses 6-8; C uses 9-11; D uses 12-14. A separate host is optional. A non-player can sort the sheets, or each person can print only their own seat pages. Do not pass a complete open printout around the table: that exposes other seats' words before play starts.
Keep one panel visible
Choose an unused round number together. Cover every panel except that round on your own sheet. Read your word silently and keep the sheet facing you. Do not look at another seat or at the Host answer reference.
The printed sheet does not label a majority or odd role. A player should work out whether their word fits the conversation from the clues, rather than from a visible badge. The supplied deck balances the odd seat across the twelve rounds, with three odd assignments per seat. That allocation does not prove that each word pair or speaking position is equally difficult.
Give clues without naming the word
Each player gives one short sentence about a typical feature or use of their own word. Follow the printed restrictions on naming, spelling, translations and synonyms. A generic example outside the supplied deck is a feature clue about staying dry for umbrella. That example is not a real round or an answer from this product.
The speaking order starts at A in round 1, B in round 2, C in round 3 and D in round 4, then repeats. After the clue sentences, each player may ask one other player a question. Keep answers truthful and within the same clue restrictions. Do not guess or name a possible secret word, or use a comparison naming another object or place, in any clue, question or answer. Ask in the starting-seat order, one question and one answer at a time; multiple players may question the same seat. No follow-ups or extra discussion are allowed. Use the current player rules for suspected illegal clues rather than inventing a penalty in the middle of a round.
Write votes before revealing them
Every player privately writes a different seat's letter: A, B, C or D. Self-votes are not allowed. Reveal all votes together, then reveal the four words. Three should match. The remaining seat is the odd seat.
Each majority player earns one point if their own vote identified the odd seat. The odd player earns two points if fewer than three votes identified them, otherwise zero. A split vote does not remove anyone: everyone remains for the next round. Record points on the table sheet, then use a fresh round. At the end of the agreed session, the highest total wins; a tied total produces shared winners.
Pause when information is spoiled
If a word is shown too early, someone votes for themselves, or a clue, question or answer breaks the printed restrictions, stop and mark that round VOID. Nobody scores. If the group cannot agree whether a clue, question or answer was legal, void the round rather than forcing a disputed result. Use a new round. If a word is unfamiliar, void it without requesting a definition that would expose it.
You may skip your clue or question and still vote. All four must vote to score. If anyone leaves or declines to vote, void the unfinished round and end the session, keeping completed-round points. Start without a timer. The planning allowance in the rules is provisional, not a measured session duration. Fixed rounds have a replay limit: a group that already knows the words has lost the discovery that supports deduction.
Choose it for the right table
This game creates private information, conversation, a simultaneous vote and a reveal. It is not a solo worksheet or an open-clue cooperative ordering puzzle. It needs four players and spare paper for concealment and votes, but it does not require scissors, an app, an account, a phone or a separate facilitator during play.
The pack supplies prepared 3+1 assignments, rotating speaking order and exception handling. Free digital alternatives are strong; using printed sheets instead of devices is a functional choice, not proof of better entertainment or paid demand. KitFlow does not claim to have invented the common hidden-word mechanism.
The delivery is a static PDF pack: four PDFs covering player and host materials in A4 and Letter, plus Start Here and a license. Editable production code is not included. Printing and paper are not supplied. Physical printing and human playtesting have not been performed; any published fit or timing information must retain that boundary.
