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.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
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 disheartened to learn that this game used Gen AI. Sorry, I can't recommend anyone play this, and I regret spending money on it. I will be more diligent in the future.

If I had known that the development team had used AI to make it, I wouldn't have bought it.
医学奇迹:前20分钟晕3D得想吐,强忍着解锁两个魔法之后居然不晕了(可能因为无需集中注意),甚至越玩越来劲一口气通关,魔法真好用啊。 [spoiler]原来...书籍整理魔法是存在的...[/spoiler]
Le jeu parfait pour tous les détraqués qui adorent classer et ranger, mais seulement dans les jeux vidéos.
I played before learning there was generative AI assets used within the game for the book covers, and they seem to have no intention of taking them out. Find another sorting game.
I never thought a game about cleaning a library would be so good. If you like tidying activities with a handful of upgrades, check this game out. I didn't explicitly notice AI content, and performance was fine with my computer.
This game is absolutely wonderful. It is so satisfying and relaxing to play. I look forward to future updates!!!
As a few other reviewers have noted, the AI disclosure for this game was added later, leading people who otherwise would not have supported this game to purchase it. 1) That's trashy as hell. 2) There is no reason you needed to use AI at all in this game. I'm not gonna be like some others and assume you were lying about the extent, so assuming you were honest, you could have easily done those things without relying on generative AI. The concept was good, the gameplay was good, some of the book titles were extremely funny, and yet you decided 'just a little' genAI was fine? That's like baking brownies and thinking adding 'just a little' dog poo was fine. Do better.
I was finally able to do the last achievement after an 18-hour run, counting the times I went AFK. This was absolutely insane to do, yet it was so satisfying to see the blue lights on every category after using no magic at all. It had been a while since I played a game that made me stay up so late day after day without me even noticing.
