It all began when you opened that letter. Penned by your late master, it details how you are now heir to his mysterious legacy. You set off for the island on which he'd spent his final years... and so a truly unsettling journey begins, a journey into the deepest secrets of magic and the occult.

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): 0/day in the week to Aug 20 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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
49 Keys is a narrative-focused game that will test your wits and nerves. Peruse the pages of a Lovecraftian tale, interact with maps and solve the puzzles encountered along the way. Trace your master's footsteps to uncover the deepest secrets of the arcane, on a quest brimming with horror and magic.
Embark on a Disturbing Journey
Alas, I knew not of the extraordinary, bizarre, and gut-churning sights that awaited within those walls.
The year is 1520. You receive a letter from your old mentor, the first step on an unnerving journey like none before. One that shall expose you to the forbidden arcane and all its mystery in which you shall concoct mixtures both wondrous and strange, and summon forth beings of other-worldly power. You must steel yourself, for terrors buried deep within shall soon awaken within you, Dantean horrors that bleed into reality. Endure these trials and, in time, the truth shall draw near. Yet will you be brave enough to pay its price?

An Immersive Literary Feat
Its lauded writing aside, 49 Keys is an audio-visual work of art. Intricately-designed menus hark back to manuscripts of the Middle Ages through to the Renaissance, with a unique art style throughout. Pore over incredible full-colour illustrations, and feel the thrill as original themes perfectly complement each twist and turn. All this combines for a deeply immersive world.

Unique Riddles and Marvellous Mysteries
Akin to point-and-click adventures, 49 Keys has you search through a meticulously-crafted world collecting items to aid you in solving its intricate puzzles. Read every word with care, for vital clues are hidden within. Put your reasoning skills to the test, and push onward; but fear not—an array of detailed in-game tips are at hand, if ever you need them.

Directly Adapted From The Best-Seller
49 Keys was developed and adapted by the original author behind the 2022 gamebook of the same name (49 Chiavi), a best-selling puzzle adventure. Gaining overwhelming praise from critics, it also achieved a place on Italy's 2022 gamebook best-seller list, going on to win two highly-coveted awards that year.

垃圾得很别买,全程旧纸底色上的简陋的线描图,即使是这样的图像也少得可怜,百分之就是的游戏内容就是读文字猜字谜,想读书直接去看小说好了,何必来玩这个又臭又长的枯燥游戏
指引很差很对脑回路的同时又几乎是线性流程,不喜欢,,,
Pretty fun little puzzler. Has good prose and great atmosphere. I did find all the puzzles pretty easy (except [spoiler] using the red eye drops on the mirror [/spoiler]) but also clever enough to be enjoyable. My biggest gripe with the game is that it is [i] extremely [/i] short of my 4 hours of play time nearly half of that was from repeat playthroughs for the speed run and all endings achievements. As such, for those on a budget I would not recommend this game.
之前就对这款游戏感兴趣,趁着冬促直接拿下了。感觉体验下来游戏的整体难度还是比较高的,需要一定时间的思考,但是看到本作是由同名畅销解迷书改编的一下子就理解了游戏谜题难度为何如此设计,并且游戏中也设计了完善的提示系统,玩家并不需要担心卡关的问题,游戏归给予细致的引导帮助。 游戏的氛围营造效果很好,游戏的剧情表达方式比较特殊,有点像一位说书人正在娓娓道来手中书籍的故事。或者换种说法玩家可以把这款游戏当作一本单人的解密本,去寻找自己的导师在孤岛上留下的宝藏。剧情的题材偏向玄幻色彩中融合黑暗元素,在那泛黄的羊皮纸上书写着黑色的字迹,书上刻画的图案都非常细腻,满满的中世纪风格,真的很有感觉。再加上剧情中玩家可以获得隐身、水上行走这种不可思议的魔法与书中出现的炼药环节,又使得整体游戏氛围蒙上一层神秘学的面纱。
7/10 解谜书的形式,看起来比较新颖,本质上其实就是文字解谜 主角对迷宫的探索让我想到《化学婚仪》(以七日婚礼仪式隐喻炼金过程中物质的转化,这使得整个故事很多地方读起来都很幽深),推荐对炼金、占星和宗教感兴趣的玩家购入。
[h2]An incredible atmosphere had been crafted in this interactive book[/h2] [b]For the most part, this game is like reading a book (I'd say the game is ~90% reading), but it also kind of plays like a dungeon crawler and escape room, while having a few interesting puzzles to figure out here and there.[/b] 49 Keys is expertly written, the text is eloquent, and feels fit right in the medieval era it is set in. The story is very good, it explores occult and mysterious themes, in search of the cryptic book of your Master, his grand work of '49 Keys'. Higly recommended if you are looking for a dark, medieval story. The few puzzles this game has are not easy, but can be figured out with some moderate effort, if you pay attention to the texts and clues. Still, I would not say this game is a puzzle game. There are 4 different endings, and the 'good' ending(s) can be easily missed. And since there are NO manual saves, if you choose a wong option, you get locked out of it in that run. Though you can speedrun the game in about half an hour or so, it is just not worth it IMHO, for the extra few pages the different endings give you. Just read them in the Guides page, you won't miss anything. For some reason, the games rating is dragged down by chinese reviews exclusively. This game does not deserve it, this is an awesome game if you feel intrigued by the general premise of an interactive book.
