Modeled estimate, not a reported figure. How we estimate →
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 54.14/day in the week to Sep 1 → 98.14/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
A mischievous fairy has left the once-majestic library in utter chaos. The principal’s word is law: "You are forbidden from leaving until all 3,072 books are returned to their rightful places!" In the silent, mystical archive, your long battle against the mountain of books begins.
Categorization: From Destructive Magic and The Travels of Otherworld to Romance Novels—use titles and cover designs as clues to transport a massive collection to the correct sections.
Massive Volume: With 3,072 books to organize, the task may seem overwhelming at first. However, as you stack each book, you will unlock magical abilities that drastically boost your efficiency.
Visual Satisfaction: There is a special joy in seeing the books that once cluttered the floor return to the shelves, slowly revealing the hidden floor beneath. As chaos transforms into perfect order, you’ll experience an unparalleled sense of satisfaction.
Strategic Efficiency: How will you combine your unlocked abilities? What order will you tackle the mess? The strategic fun lies in your decision-making, as your tactics can lead to a dramatic increase in workflow.
Immersive Atmosphere: The library’s ambient sound and BGM change dynamically; as shelves fill up, the acoustic resonance grows stronger, drawing you deeper into the world.
The Principal’s Strict Evaluation: Your precision is being monitored. The Principal’s evaluation shifts in real-time based on how many rows are "correctly shelved" according to the rules. Accuracy and speed are the keys to a perfect score—and your escape.
Assemble: A spell that summons other volumes of the same series directly to your hands.
Insight: Highlights other volumes of the same series, making them easy to spot even in a disorganized pile.
Auto-Shelving: A spell that instantly places the books in your hands onto the shelves in perfect order.

Very good relaxation game. I'm the sort of person who gets stressed trying to maximize cooldown timers, but by the end this game lets you upgrade them so much that the stress went away because I had minimal downtime waiting, so the game went through waves of relaxing, to stressful, to satisfying. This game got me to realize how much I enjoy organizing as a core game mechanic, as I usually only engage with this much of it when playing expansive survival sims.
hands down the best game ive played within the last 6 months. my brain is mush

Un jeu très simple mais vraiment addictif.
Creo que su gran problema es que las ultimas horas con las magias maxeadas pierde la gracia. Pero para lo que vale tampoco le vamos a exigir más
Wish I could go there for real... also can't help but think that something that would improve the game a touch would be if all of the volumes had individualized subtitles (from letter ranges to actual topics).
Very satisfying game, for the price I think this ammount of play time is great.
I really enjoyed playing this game. It's built to be playable over and over again and that's exactly what I'm doing with it. If you enjoy organizing games and whimsy, this may be a good fit for you.
Now this is a simple but addictive and incredibly well game
Very fun, the titles alone are amusing to read. It's very rewarding and low pressure. I'm curious to see what the devs will come up with next!
something to throw a few hours at unless you can find a complete set or two :D
