Solve a treasure hunt book

An escape room you can do at the kitchen table: riddles that unlock the next page, and an answer key you are not supposed to open. Journal 29 and the EXIT books are the usual way in.

One murder, a grid of suspects, weapons and locations, and just enough clues to eliminate everything but the answer. There are hundreds, in books and one a day online.

Cover to cover, not the two you do on a train: a book of nonograms, sudoku, kakuro or logic grids, finished to the last page.

A dead man possesses objects to rewind deaths; Shu Takumi's puzzle mystery.

Nine strangers on a sinking ship with bomb bracelets; the escape-room visual novel.

Sixty dead sailors and a pocket watch that shows the moment of death; Lucas Pope's 1-bit mystery.

Nine people, an ally-or-betray vote every round, and a flowchart you jump around to reach the truth.

Four panels you rearrange like a comic to tell a story; one artist, seven years.
