Find today's book, clue after clue

You don't pick from a list: you guess books, and the game reveals what they share with the answer. Scroll to watch a round play out.

1

Guess a first book

You try “La Ferme des animaux”. Author and publisher turn green. But the book you want is later, and much longer.

2

Read the clues, then narrow it down

You try “Le Meilleur des mondes”: the genre fits, the author doesn’t. You now know it runs past 311 pages.

3

Found it!

Orwell, 1949, 328 pages: “1984”. Every clue turns green.

The idea

A real deduction game for readers

1jour1livre is a free guessing game where, every day, a new book is waiting to be found from its cover. You guess other titles, and the game reveals clues — author, publisher, subjects, page count, first publication year — based on what they share with the mystery book.

This is not a quiz: every guess is a strategic choice. Cross-reference the clues, tighten the era, and find the book of the day in as few tries as possible — then share your score.

Classics, contemporary novels, essays: the pool is drawn from the most-read works, not from forgotten shelves.
