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 17 day-to-day chart moves that followed a price cut, against 2,502 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.

Reviews
Librarian: Tidy Up the Arcane Library! turns the daunting task of shelving 3,072 scattered books into a strangely satisfying spatial strategy game. If you're an achievement hunter, make your first playthrough completely magic-free. While finishing rows unlocks efficiency-boosting spells, rejecting every upgrade and hauling all 3,072 volumes through pure foot traffic transforms a breezy sorting sim into a rewarding test of pure organizational grit. Highly recommend - skip the magic if you're a total masochist.

Super simple, but fun little game. Worth the few bucks to buy!
無事にお片付け完了!面白かった! 自分的には後発のSMシミュの方が好みだった。 全て同じ本に見えてしまって、なかなか分別ルールが判断付かず魔法に頼ることがほとんどだった。
I love LOVE this game. I only played through twice- but there will be more, in fact, now that I am writing this- I think I'm just going to go ahead and re download it so I can replay it. Again.

Como uma pessoa que adora jogar com toda a paz do mundo, eu amei. Simplesmente levei umas 18 horas para terminar tudo, quase não usei os poderes e fui jogando aos poucos, sem pressa nenhuma. Super recomendo para quem quer dar uma desestressada.
helps calm my brain when things get overwhelming! brilliant chill out game
It is a simple, fun and cozy game to play. Enjoyed the user friendliness of this game and the overall objective.
Amazing game. My ADHD went wild doing the anti magic run! Only complaint is that I don't understand why the Curry/Poop book is in Psychology?
