THE GUIDE

Petit Bac: categories, letters and rules

Eighty ready-to-play categories, the six letters to drop, and a way to start a round without looking for a pen.

Petit Bac fits in one line: one letter, five categories, everybody writes at the same time. What separates a flat game from one you keep replaying is the categories you pick and the letters you draw. This page gives you both, in the version we play at our own table and built into our online game.

Categories and letters taken on 12 September 2026 from PlaySobr's Petit Bac, which this page uses as its reference.

The rules in five lines

A letter is drawn at random. It holds for the whole round.

Five categories are announced, the same for everyone. Each player writes one answer per category, starting with that letter.

The first player to fill all five boxes ends the round. Everyone else stops immediately, even half-finished.

Answers are read out loud, category by category. A valid answer nobody else wrote scores two points, a shared answer scores one, an empty box scores nothing.

Draw a new letter and play again. A game runs five to ten rounds depending on the table's appetite.

How many players, how long

With two players it works but loses its bite: answers almost never collide, so almost everything scores two. From four players on, collisions start and the game becomes a race for the idea nobody else will have.

Past eight players, reading the answers takes longer than the round itself. Read every other category out loud and leave the rest to the scoring.

A round takes one to three minutes. Our real games run around eight minutes for five rounds, arguments included.

The forty party categories

Same rules, categories that make the table talk. They are written for adults who know each other: half the fun is in reading the answers out, not in the score.

Which letters to draw, which to drop

Six letters empty the categories in French and waste a whole round: K, Q, W, X, Y and Z. Take them out of the draw. Twenty playable letters remain, A through V.

Three more deserve to be rare without disappearing: J, U and V. They produce short rounds where two people land on the same obvious answer. In our online game they come up three times less often than the easy letters.

If you draw by hand, write the twenty letters on slips and remove the one that just came up. Otherwise the same letter returns later in the evening and the second round is already played.

Scoring without arguing

The classic scale is two points for a unique answer, one for a shared one, none for an empty box. Some tables add a five-point bonus for whoever ended the round. We advise against it: it rewards writing anything quickly.

The real source of arguments is not the scale, it is validity. Two rules are enough. A contested answer goes to a show of hands, simple majority, no debate. A proper noun counts if at least one other person at the table knows it.

Score after every round, not at the end. Deferred scoring turns the last round into an accounting session.

Variants that hold up

Letter at the end. The answer must end with the drawn letter instead of starting with it. Harder, and best kept for tables that have already played three classic rounds.

Secret categories. Everyone whispers a category to the host, who draws five of them. Players discover their own at the same time as the others.

Single theme. Every category revolves around one subject: cooking, cinema, school. Works well for a birthday or a family meal.

Lightning round. Thirty seconds, three categories, nobody stops before time is up. A good last round to finish on a fast note.

On paper, printed, or online

On paper, each player draws a table of five columns and one row per round. That is the original version and it needs nothing but a pen each.

For printing, the most practical format is a blank grid where categories are written in by hand at the start of each round. A pre-filled grid locks the categories for the whole game and wears thin after three rounds.

Online, everyone plays from their own phone, the categories and the letter arrive at the same time for everyone, and scoring happens on its own. That is what we built, precisely because the friction in Petit Bac was never the game but the equipment: finding pens, drawing grids, deciphering other people's handwriting.

Frequently asked questions

How many categories per round?

Five. Three makes rounds too short for collisions to happen, seven stretches the reading until people start skipping categories. Five is the number where a round lasts about two minutes.

Which letters should be removed?

K, Q, W, X, Y and Z in French. They leave half the table with empty boxes, which is neither funny nor worth arguing about. Twenty letters remain, plenty for an evening without repeats.

Can you play Petit Bac with two people?

Yes, but the game changes. With two players shared answers are rare, so nearly everything scores two and the score stops separating anyone. Play against the clock instead: whoever fills all five boxes first wins the round.

How do you settle a contested answer?

Show of hands, simple majority, nobody pleads their case. It is the only method that stops a two-minute round turning into a ten-minute debate. Agree the rule before the first round, not at the first dispute.

What age is it for?

The classic categories work as soon as children write on their own, around seven or eight. The party categories are written for adults and have no place at a table with children.
