What is Ten Questions?

It is the daily game where you run the investigation: a secret player, up to ten yes-or-no questions and three guesses. The player is the same for the whole world and changes at midnight.

No: questions come from the day's menu of about thirty. Free-text questions would need language interpretation, and this project does not do that — the menu already covers country, continent, position, decade, clubs, retirement, caps and birth year.

Why can I not ask about trophies or leagues?

Because the database cannot back the answer. It keeps each player's BIGGEST honour, not the list — so "did he win the Champions League?" could not honestly be answered "no". And it keeps nothing about leagues: only the club's country. A question answered by guesswork is an invented fact, and that does not ship.

Does asking cost a guess?

No. They are two separate resources: ten questions and three guesses. You can guess straight away without asking anything.

Are ten questions enough?

Measured: a player who always picks the question that splits the field the most ends the ten with 2.6 candidates on average — and still has three guesses. Almost half the days end on a single name.

How to play Ten Questions

In Ten Questions you run the investigation: there is a secret player, and you ask up to ten yes-or-no questions before naming him in three guesses. It is the reverse of Craque Oculto — there the game reveals and you react; here you lead.

The rules, in 20 seconds

Ten questions. Picked from the day's menu, each comes back YES or NO.
Three guesses. Type and pick a name from the list.
Asking costs no guess, and guessing costs no question: two separate resources.
The day ends when you get it right or spend the three guesses.

What you can ask

Country and continent — "is he from…"
Position — "does he play as…"
Debut decade — "did he debut in the…"
Clubs — "has he played for…" (the chip carries the crest and the country, because there are two Liverpools and two Américas in football)
The loose ones: has he retired? more than 50 caps? and was he born after… on a grid of years every 5 (1965 to 2000) — you can bisect: "1990? no → 1980? yes → 1985?" closes a five-year window in three questions.

An answer that already follows from the previous ones is free. If "born after 1990?" was NO, "after 1995?" is NO too — the game marks it for you, in the notebook, without spending a question. Same when a country (or continent, position, decade) gets a YES: the others in that group leave the menu already answered.

And what you cannot — with the reason

Three obvious-looking questions stayed out, and not out of laziness: the database cannot back the answer, and a question answered by guesswork is an invented fact.

"does he play for club X today?" — "today" ages with the file: a day published in March would answer wrong in August. "Has played" does not age;
"did he play in the Premier League?" — the database keeps the club's country, not the league. "A club from England" would be an approximation presented as fact;
"did he win the Champions League?" — the database keeps each player's biggest honour, not the list of them. Answering "no" to a real winner is the kind of error this site does not make.

Three strategies that work

Start with the questions that halve the field. Continent and decade split far more than one specific club.
The club question is the closer. Once you know country, position and era, a "has he played for…" usually nails it.
Keep a guess. With two or three good answers, guessing early is sometimes worth more than spending all ten questions.

Frequently asked questions

When does the player change?

At midnight, in your device's local time. Everyone plays the same player on the same day.

Is my progress saved?

It is, in your own browser — including the questions you already asked — and separate from the other games.

Does sharing give the answer away?

No. The text says how many questions you used and on which guess it came, without the name and without what was asked.

Are there other games?

There are: Craque Oculto, Four Clubs and Five Teammates, among others.
