Game night finally gets a referee.

Zebra is a small device that sits in the middle of the table, listens to the game, and makes the calls: what counts, what’s clever, what’s a stretch, and who’s ahead. It runs entirely on the device. Nobody has to be the judge.

Fourteen classics with the arguments taken out. Seventeen new games that only work with a judge in the room. Fourteen ways to play trivia.

Small primate from Southeast Asia. Capped at 5.

Pick an answer to hear the call. Points are bits of surprise: one point each time the odds of someone saying it halve, capped at 5. Frequencies in this example are illustrative.

Most party games are built around a missing judge.

Look closely at the rules of the classics and you find workarounds for one problem: nobody at the table can score fairly, quickly, and without an answer key. Take that problem away and the workarounds become optional.

The workaround: Scattergories only rewards answers nobody else at the table wrote, because no one can score cleverness.

What a judge makes possible: Score every answer by how unlikely it was, so tarsier beats tiger even if nobody else said either.

The workaround: Apples to Apples hands judging to a rotating player, because there's no neutral one.

What a judge makes possible: A neutral judge with a declared taste you can play to, and a reason for every pick.

The workaround: Family Feud needs a survey of real people, run long before the game.

What a judge makes possible: Survey any crowd about any question on the spot: 100 nurses, 100 kids, 100 people in 1985.

The workaround: Werewolf makes one friend sit out and run the night as moderator.

What a judge makes possible: Everyone plays. The device deals roles, runs the night, and never gives anything away.

The workaround: Taboo and Codenames run on the honor system and a lot of arguing.

What a judge makes possible: Every clue is checked the moment it's said, including the sneaky forms of a banned word.

There’s a second unlock. Every Zebra runs the same frozen judge, so a score in one living room means the same thing in every other. Games that were always too subjective for rankings can finally have leaderboards.

One small thing in the middle of the table.

About the size of a coaster. It replaces the scorepad, the timer, the rulebook, and the friend who always ends up arguing about what counts.

Hears the whole table

Four microphones pick up everyone and tell which seat each voice came from.

Shows and says every call

A round display and a speaker give the ruling and the reason. The ring lights whenever it's listening.

Knows who's playing

Tap a seat token to join. Tap it again for private moves, like voting at night in Werewolf.

Takes challenges

Tap the top to challenge a call before it locks.

Runs offline

Speech recognition, judging and scoring all happen on the device. No account, no connection.

Sees, if you want it to

An optional camera clip-on for drawing and scavenger games, with a physical shutter.

Trivia, judged properly.

Free answers instead of multiple choice. “Which Roosevelt?” asked instead of guessed. Scoring that rewards knowing how sure you are, or how close you got. And a quiz night where the host never grades another slip.

“Roosevelt”Which one? Two presidents fit.Ask
“Frankin Rosevelt”Misspelled, but it can only mean one person.Accepted

Classic, retrofitted

Survey Says

Any question, any crowd, surveyed on the spot.

'The fridge.' Number 2 on the board, 31 of 100.

Missing Link

Get from pickle to Napoleon in as few steps as the judge will allow.

'Pickle to brine' holds at 91. 'Brine to Napoleon' breaks at 12.
Rules and scoring: Missing Link

Fair enough to argue with.

Every call comes with a reason. The same answer always gets the same call. Anyone can challenge, and hidden rules are sealed at the start so nobody can claim the judge moved the goalposts.

Read the fair play rules

Everything stays on the table.

Zebra listens only during a game, and only while the ring is lit. Speech is turned into text and thrown away as it goes. Nothing leaves the device unless you choose to share a scoresheet.

How privacy works

The Daily.

One prompt a day for every Zebra in the world, judged by the same model. Play it alone in a minute or with the table after dinner, then see where your answers landed against everyone else’s.

It’s the reason to take Zebra off the shelf on a Tuesday.
