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 2,400 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.

Reviews
I really loved the gameplay and the obsessive rhythmic loop you can get into with this game, but I cannot recommend this game as long as it used AI for any part of its creation. Extremely disappointing as it for sure did not need it! Makes me feel like the developers can't trust their own abilities or players.
I liked the concept of this game, but I wasn't aware the game uses Generative AI. Making the paintings on the walls with Gen AI is not "supportive work". Thankfully I'm just under the refund mark and should get my money back. Would not recommend if you have standards.

I liked this game, until I found out it was Gen AI.
boring game, didn’t realize it was AI or i never would’ve bought it. removing it from my account so i don’t even have to look at it
I love sorting games like this, they are so much fun for me and tickle my brain in just the right way. HOWEVER, I do not recommend this game due to their use of AI, humans have been making video games for humans for the past 40 years- there's no need to bring a fake intelligence into the equation.
It's too late for me to get a refund. But this games uses AI for the most pointless reasons (entirely on me I should have checked). Grammar? Just pay someone to do it, if its that important. The artwork on the walls?!?! Find some free asset (there's so many if you look) if you refuse to pay for it.
Previously undisclosed AI.
I'm genuinely really sad to be writing this review in this fashion. This game was everything my AuDHD heart desired. I LOVE this game, as evidenced by the fact I've already got well over 40 hours in it. But I missed the AI disclosure and had I seen it, I would NOT have gotten it. It's heartbreaking as an artist to see other creators relying on the use of GenAI when it does so much damage to other creatives and the environment both. It's unethical, it's actively *harmful* and it should not have been used at any point in the process to create this game. This game was perfect but for that, and I'm genuinely upset one of my new favorite games is one I can't ethically play anymore.
Tired of any AI usage in games. I regret this purchase, I bought it on a whim. Should've looked in the BURIED disclaimer that Steam refuses to put higher up to better inform buyers. The game was okay, the mechanics trivialize the game and there was NO REASON to not hire artists or editors/spellcheckers to give the game a once over instead of using AI generation for SIMPLE ASSETS. I'm sad to have contributed to the growing expansion of AI-usage in game development and now there's a trend of other garbage sorting games like simulator games on Steam. Don't play, don't buy, don't support.
Heavy use of AI throughout it, not recommended.
