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

The daily challenge, a ranked mode at your level, and real-time duels.
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.
