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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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.

Love these chill games.
So satisfying. So frustrating. The level of detail that went into the design of the covers of the books is incredible. The design of the math books is so identifiably a text book. I find myself identifying books by the covers as much as the titles. It truly is fantastic.

I really really enjoy this game - tho I personally find it more fun to sort without the magic help. I wish there was a multiplayer on this bc I think it would be so fun to just spend time together with my friends sorting through all of the books like little book worms
For a game made by only TWO people, this is honestly amazing. If you’re looking for a calm, relaxing game that you can just sit down and get lost in, I highly recommend it. Even my 6-year-old got into it and enjoyed playing with me! My only complaint is that I loved it so much I managed to complete the entire game in ONE DAY. 😂 It’s seriously addictive. I would absolutely love to see DLC in the future with expansion rooms, more books, upgrades, areas to unlock, or even more secrets to discover. I would happily keep expanding that library forever. Absolutely loved this game. 10/10. 📚❤️
好玩,专制强迫症!!!无聊的时候整理一下感觉又累又解压。。。。
Good game, a bit tedious initially but it ended up captivating me for way too long until I completed all the achievements. Would give it around a 7/10 difficulty to 100% just based on time alone.
love the game is there any more rooms after done first one
Muito bom! Só que eu vi que tem mágica só no final, mas mesmo assim eu tava querendo um jogo que me fizesse desacelerar. Acho que vou abrir outro save só pra ir atrás das mágicas hehe.
This game is shockingly resource intensive, however, it is very fun. A good time killer that has surprising replayability. Worth the $5 I paid.
as an autistic person that loves sorting stuff this is my literal dream come true
