Just One Board Game | How to Play and Win

Just One is a cooperative party game for 3 to 7 players, aged 8 and up, where everyone except the guesser writes one word clue, duplicate clues are cancelled before anyone sees them, and the whole table shares one score out of 13 mystery words.

If you have a group that ranges from a ten year old to a grandparent and you need a game that all of them can play in the same twenty minutes, this is the one I keep reaching for. Just One takes about ninety seconds to teach, fits on a coffee table, and has no elimination, so nobody sits out. It is also the rare party game where the funniest moment is a word that never gets read out loud.

The whole design sits on one rule. Every player writes a single clue at the same time, in secret, and any two players who write the same word have both clues thrown away before the guesser is allowed to look. That one rule converts a simple word association game into a game about guessing what your friends are about to say, which is a completely different and much better game.

If Codenames is the word game your group already owns, the difference is the scoreboard. Codenames splits the room into two teams and points them at each other. Just One puts everybody on the same side and points them at the deck.

One thing before the rules. The old version of this page never told you how you win, never gave the player count, and described the failed guess rule incorrectly. Everything below is checked against the English rulebook, and where the old page was wrong, it says so.

How you win Just One, and why the deck is a 13 card budget

You win by guessing as many of the 13 mystery words as you can before the deck runs out, and the perfect score is 13.

At setup you shuffle the whole deck, draw exactly 13 cards at random, and return the other 97 to the box. Those 13 cards are the game. Every turn one of them is played, and when the last one is gone the game is over and you count the cards the group guessed correctly. There is no way to lose, no elimination and no hidden traitor. The rulebook just prints a rating scale so you can compare tonight’s table to last month’s.

Correctly guessed cards	What the rulebook calls it
13	Perfect score! Can you do it again?
12	Incredible! Your friends must be impressed!
11	Awesome! That is a score worth celebrating!
9 to 10	Wow, not bad at all!
7 to 8	You are in the average. Can you do better?
4 to 6	That is a good start. Try again!
0 to 3	Try again, and again, and again.

Here is the part that almost every short summary gets wrong, and it is the real engine of the game. The guesser gets exactly one guess, and a wrong guess does not just lose the card in play, it also sends the next card in the deck back to the box. A miss costs two cards, not one.

What happens on the turn	What it costs the deck	What the table scores
The guesser names the right word	Nothing extra, that card goes face up next to the deck	1 point
The guesser guesses wrong	That card and the top card of the deck both go back to the box	0 points, and two cards gone
The guesser passes	Only that card goes back to the box	0 points, and one card gone
Every clue is cancelled	That card goes back to the box and the turn jumps straight to the end	0 points, and one card gone

That is the whole tension. Passing is cheap and a wrong guess is expensive, so a group that is staring at three weak clues and no idea should absolutely pass. There is one sting in the tail: if the guesser guesses wrong on the very last turn of the game, the rulebook also removes a card the group had already guessed correctly. The last card of the deck is the one place where being brave can cost you a point you already banked.

Then the player to the left of the guesser becomes the new guesser, everybody erases their easel, and the next turn begins.

How a turn works in four phases

A turn is four phases in a fixed order: the guesser picks which word, everyone else writes one clue, the duplicate clues are cancelled while the guesser’s eyes are shut, and then the guesser gets one guess.

Phase	What happens
1, choose the mystery word	The guesser draws the top card without looking at it and sets it on the easel so every other player can read all five words, then names a number from 1 to 5
2, clue selection	Everybody else secretly writes one single word on their own easel, with no talking and no looking around
3, comparing clues	The guesser closes their eyes, everyone turns their easel around, and identical or invalid clues are cancelled by tipping the easel over
4, guess	The guesser opens their eyes, reads whatever survived, and gets exactly one guess or a pass

Two details in phase 1 matter. The card is turned towards the other players, never towards the guesser, and it is the guesser who names the number. If the table does not know the word that number lands on, the rules let them ask the guesser to pick a different number instead. That single line is the reason a seven year old can sit down at a table of adults and not be stuck.

Phase 2 has a generous definition of a word. A digit counts, so does a number, an acronym, an onomatopoeia and a special character. The rulebook’s own examples are that 007 is a legal clue for Bond, that Riiiiiinnng and SMS are legal for Telephone, and that a dollar sign is legal for America.

Five things are not legal clues, and they are worth knowing before somebody argues about it:

• The mystery word written differently, so “Shurt” is out when the word is Shirt.
• The mystery word in another language, so “Buisson” is out when the word is Shrub.
• A word from the same family as the mystery word, so “Princess” is out when the word is Prince.
• An invented word, so a mash up made up on the spot is out.
• A word that sounds exactly like the mystery word but means something else, so “Whether” is out when the word is Weather.

Phase 3 is where the game is actually played. While the guesser’s eyes are closed, everybody turns their easel around and reads everyone else’s clue. Identical clues get tipped over and hidden, and they stay hidden. “Identical” is broader than most groups expect: two copies of the same word are identical, plurals and gender variants and spelling mistakes all count as the same word, and Prince and Princess count as identical because they are from the same family. If every single clue is cancelled, the card goes back in the box and the turn is over.

Phase 4 allows exactly one guess, and a guess that sounds like the mystery word counts as correct even if it is spelled differently.

What is in the box, and who made it

Just One is a 2018 design by Ludovic Roudy and Bruno Sautter, published by Repos Production, for 3 to 7 players aged 8 and up, running about 20 minutes.

The rulebook credits Ludovic Roudy and Bruno Sautter as the designers, the same pair behind The 7th Continent, with art by Eric Azagury and Florian Poullet. Repos Production, a subsidiary of Asmodee, published it in 2018. It won the Spiel des Jahres in 2019, which is the German award that usually goes to a game families will still be playing in a decade.

There is a nice bit of history attached to it. The game was originally published in French as We Are The Word by Fun Consortium, and Repos bought the rights in early 2018, rebuilt the components, added fifty words and gave it the name it has now.

Component	Count in the box
Mystery word cards	110, with five words printed on each card
Easels	7, and one side of each easel has a small support that holds the card for the other players
Erasable felt markers	7
Rulebook	1

Because there are seven easels, seven is the hard ceiling on the table, and it is a genuinely comfortable one. The whole game is 110 cards with five words each, so 550 words in the box, but only 13 cards ever make it into a game and the rest stay in the box.

The current reprint, listed on BoardGameGeek as Just One: New Version, keeps the rules identical and swaps the dry erase markers for erasable crayons. Nothing about how the game plays changed, so a guide written for the original still teaches you the current box.

Player count: why the box says 3 to 7, and where it sings

Just One is a 3 to 7 player game, and the sweet spot is four to seven.

Three players is not only legal, it has its own printed variant. At setup each player takes two easels instead of one, and during clue selection each player writes one clue on each easel. Every player therefore supplies two clues instead of one, and identical clues are still cancelled exactly as normal. Without that variant, three players would mean only two clue givers per turn and duplicate clues would almost never fire, which would remove the whole point of the game.

Four to seven players is where the design is at full strength. With four or more clue givers, the chance that two people land on the same word becomes a live risk on every single turn, and that risk is the game. Six and seven players is the loudest version, and if that is your normal table size our guide to the best board games for 6 players is the longer version of that conversation.

Two players is not a legal count. The box says 3 to 7, and the rulebook contains no two player rules at all. The old version of this page claimed the rules “technically support it”, which is simply not true, and with one clue giver there is nobody to collide with anyway, so the game collapses into a very plain guessing exercise. If you want a two player word game, that is a different box.

Corrections: what most guides get wrong about Just One

The old version of this page got four things wrong that would change how a group plays, so here they are side by side.

What the old page said	What the rulebook says
A wrong guess puts the word card in a “lost” pile, and whether you get another chance depends on the variant	A wrong guess sends that card and the top card of the deck back to the box. There is no lost pile and no such variant
The aim is to reach a score threshold by the end of the game	The deck is exactly 13 cards, you count the cards you guessed correctly when it empties, and the printed table is a rating scale, not a threshold
The rules technically support two players	The box and the rulebook say 3 to 7 players, and there is a printed variant for exactly three because three is the floor
The cards are numbered 1 to 13 and higher numbers are harder words	Each card has five words, and the guesser names a number from 1 to 5 to choose which one is the mystery word

Three more worth clearing up while we are here. The game has no lives to lose, despite what a lot of summaries say, it just has a shrinking deck. The old page also described the guesser placing the card on their own easel without looking, when in fact the card is turned so that every other player can read it. And the old page put the play time at 20 to 30 minutes, where the published figure is 20 minutes, which is about right for a table that knows the game and a little optimistic for a table that does not.

House strategy: how we play it well (not official rules)

This section is our house advice, not the rulebook, and none of it is official.

Ask for a different number early. If half the table does not know the word that the guesser named, use the rule that lets them ask for a different number. A round the group cannot play is a wasted card out of a 13 card budget, and cards are the only resource in this game.

Sidestep, do not obscure. The goal is a clue that is obvious to the guesser and unlikely to occur to anyone else at the table. A clue so clever that only you understand it is worse than a common clue, because a cancelled common clue at least took an opponent’s clue with it. Aim for the second thing everybody thinks of, not the tenth.

When in doubt, pass. A pass costs one card and a wrong guess costs two, and a wrong guess on the final turn can take back a card you already scored. Passing is not giving up, it is protecting the deck for the turns where you have a real shot.

Clue for the guesser, not for the room. The clue is not there to show how quick you are. Read the guesser, not the table. A clue that means nothing to anybody else and everything to the guesser is the highest value clue in the game.

Keep the same group. This game gets better the more a group plays together, because the real skill is predicting how the specific people around the table think. A group that has played twenty games is measurably better than a group playing its first, which is not true of most party games.

If you want a second quick word clue game for the smaller nights, Hues and Cues is the one that lives next to it on our shelf, and if you want cooperation with a whole campaign bolted underneath it, Spirit Island is the heavy cooperative shelf and a much bigger ask than this one.

Is Just One good for families? Our honest take

Yes, and this is one of the easiest recommendations on the site. Just One is a cooperative party game rated for ages 8 and up, and it is one of the very few games that a ten year old, a seven year old and two adults can all play at the same table with nobody being carried and nobody being bored. There is no reading of other players, no hidden traitor, nothing to argue about, and the whole table wins or does not together.

It earns its spot on our best board games top 50 list for exactly that reason. It is the game that comes out when the group is mixed, when the evening is short, or when somebody at the table has never played a modern board game before. Setup is handing out an easel and a marker, which means even the person who usually refuses to learn a ruleset will sit down for this one.

• Similarities: Both are fast, low component party games built entirely around giving clues so that other people can name something, and both come down to how well the table reads each other.
• Differences: Codenames is competitive and splits the room into two teams with a spymaster giving one word to several clues at once. Just One is fully cooperative, every player gives exactly one clue for one single word, and duplicate clues are destroyed before the guesser sees them.
• Why this game fans will enjoy it: If Codenames is the word game your group already owns, Just One is the same pleasure with the rivalry taken out, which is why it works for a family table where one team losing would ruin the evening.

Which Just One to buy

Version	What it is	Best for
Just One	The 2018 Repos Production original, 110 cards, 7 easels, 7 erasable felt markers, 3 to 7 players aged 8 and up	Anyone with a group of three or more who wants a 20 minute cooperative party game. This is the box to buy
Just One: New Version	The current reprint, same rules and same components, with erasable crayons instead of dry erase markers	Buyers who want the newest printing. Nothing about how the game plays changed

Buy the base game and you are done. There is no expansion, no insert worth hunting, and no edition difference that matters, because the rules, the card count and the component list are the same in both printings. If a version turns up cheap second hand, buy it, and if the markers are dried out then a fresh set of erasable markers costs less than a coffee and fixes the only component that ever wears out.

Frequently asked questions

How many players does Just One support?

Just One is a cooperative party game for 3 to 7 players, and the box lists it for ages 8 and up. The rulebook carries a variant for exactly three players, where each person takes two easels and writes two clues instead of one.

How do you win Just One?

You win by guessing as many of the 13 mystery words as you can before the deck runs out, and the perfect score is 13. There is no losing score, the rulebook only prints a rating table that runs from 13 down to zero.

What happens when two players write the same clue?

Both clues are cancelled and hidden before the guesser looks, so two players writing the same word counts as no clue at all. Plurals, gender variants, spellings and words from the same family all count as the same word.

What happens if the guesser guesses wrong?

A wrong guess costs two cards, the card you were playing plus the top card of the deck, and a pass costs only the card you were playing. On the very last turn a wrong guess also removes a card you had already guessed correctly.

How long does a game of Just One take?

A game of Just One takes about 20 minutes for 3 to 7 players aged 8 and up. Setup takes under a minute because you shuffle, draw 13 cards, hand out an easel and a marker to each player, and pick the first active player.

Can kids play Just One?

Yes. Just One is rated for ages 8 and up and it is one of the few cooperative party games a 7 year old can genuinely join with a little support. The rules let the table ask the active player to pick a different word when nobody knows the one chosen.

Is Just One cooperative or competitive?

Just One is fully cooperative, and the whole table shares one score with no individual winner. The only competition is the soft, friendly race not to write the same clue as the person beside you.
