Each volume hides one classic book. You are dealt ten crossword-style clues, every one answerable from general knowledge alone — none are taken from the book, and no names from it appear.
Every answer you ink joins the page, where the words pile up into a picture. The silhouette they form is itself the final clue.
Stuck? Take a hint to uncover the answer one letter at a time. Certain? Name the book at any moment — the earlier the page, the greater the glory. Three rejected titles, and you may simply ask to see the answer.
Scoring is golf: every clue you see and every letter you buy — on a clue or on the title — costs one point, a wrong title costs one as well, and the ledger keeps your running total across volumes. The lowest score is the finest.
There is one volume of the day — finish it to grow your streak — and the archive stays open for wandering. Records live in the memory of this device, and any finished silhouette can be shared as a picture.
