Prices
The United States storefront in every case, so this compares stores and not countries.
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): 1/day in the week to Aug 7 → 7.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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

Grow your small gem business in this short, casual simulation miner, Gemporium! Manage your time wisely between mining gemstones, refining them for more profit, and selling them to awaiting customers. After your Grandmole goes on vacation, you’re in charge of running her shop, and you quickly learn it also comes with a price of massive debt. Now, on top of building your business, you must appease the Loan Shark without going broke!
Gemporium features a timed day cycle where you have to balance completing tasks and running the gem store. Each day consists of:

Explore deeper and deeper in the local mines to stock up on gems of different rarities. Utilize various mining tools to prevent cracks and maintain the highest quality product for your shop!

Polish and prepare your recent finds in the mine to convert those lumps of rock into something collectors adore! Unrefined gemstones sell for way less than their refined counterparts, so make sure to visit the refinement table before you set up shop.

Sell your stockpile of gems to eagerly awaiting customers, but make sure to keep their tastes in mind to maximize your profit and increase your shop's reputation! The shop is only open for a limited amount of time each day, so don't be late!

Upgrade your tools, shop, and home to progress from being an anxious little mole to a master market manipulator.

For fans of a more relaxed experience, you can activate Cozy Mode to turn off the daily timer entirely and play at your own pace.

Love this game! It's really cute and the initial the looming dread of the amount of debt and the expectation of time management honestly feels kind of overwhelming at first as you get your bearings but its a really fun game once you get the hang of it! Though I would love a patch to help fix where your cursor starts when selling gems, since I have a 2 monitor set up and play games on the left every time I go to the shop to sell gems my cursor actually starts on the edge of the right monitor so the moment I go into the shop I have to click back into the game to start selling. This isn't a huge deal but with an emphasis on trying to make the most out of every moment and trying to watch something on the 2nd monitor it is a little annoying(and funny) that I almost always accidently pause what I'm watching but out of panic tab back into the game to get to selling, and only until I come back to the shop the next day do I accidently unpause it.
First off: this is a very cute indie game. I did enjoy my time with it. However, I do have a couple of things I would feel remiss in not commenting on to future buyers - this is a short experience - there is very little for character interaction. Characters talk at each other, and there's cute scenes, but no narrative choices at all - the UI is. Really rough. I'm not sure if this is the dev's first game or not but I felt like I was fighting the UI half the time. Your place in menus doesn't save, so when you're in the serving customers minigame, you continually have to keep scrolling each time back to your place to get the gem for the next customer. There's no way to see what you have for gems during the nighttime, which isn't part of the timed day. so you have to memorize how much of each gem you have to make decisionsn (like for the bats). There are two ways to format the menu for gems (it's a big list) but neither is really helpful, and I would have really appreciated some filters (filtering out non-refined gems during the selling section, for example) In general, this is a fine game with a few painpoints. I did encounter a few glitches (I think the trigger for the DLC got buried under a bunch of phone calls from the pet rock and I'm unsure if I can even access the DLC, a few lag spikes, etc) I am saying all this with the hope the devs can read it and improve in the future. I don't think it's a bad game, but I will say the devs should look into UI design for the future to avoid a lot of issues.

Залипаловка топ
Gioco carino e rilassante. La ricerca delle gemme e la relativa rifinitura diventano gradualmente più facili proseguendo con il gioco. La storia non è nulla di eclatante, ma è simpatica. Una pecca che ritengo abbastanza importante è: il debito. Dinamica piuttosto rilevante è quella di pagare una quota ogni tot. giorni. Se non lo si paga, l' unica conseguenza è il debito che aumenta, ma lo si ripagherà facilmente più avanti nel gioco. Ho comprato prima tutti i potenziamenti, ignorando completamente la cosa, poi alla fine della run in 3/4 giorni l'ho ripagato tutto insieme. Voto complessivo: 7/10
jogo curto mas muito divertido diálogos bobos em promoção e um ótimo jogo para relaxar
Gemporium is a fun cozy mining game with shop keeping! You play as a Mole who takes over his grandma's gem shop, but she owes a debt to the Sharks you must pay off. The main part of the game is digging for and cleaning gems; I wish shop keeping played a bigger part. You go into the mines and dig up gems during a digging mini game. Then you clean up and polish your gems with another mini game. Shop keeping is last (and typical shop keeping), but it's my favorite part! They recently added a timer to the day and two loan payments a week, but I disabled both of these as they make the game far less cozy. It does get repetitive, but I just play a few days at a time so I don't get burned out. This is best for PC instead of Steamdeck.
希望能降低一点难度,游戏时间太短了,一天过得好快,一下就挖几个就结束了
good casual fun game i played cozy mode as after a little bit its gets hard to do everything without running out of time
中规中矩,体感上更想打中评,思来想去还是打差评了,感觉比及格线略差一点。剧情看不太懂,有一种很浮夸的诡异氛围,不知是想故作松弛还是想讲笑话,中间还紧张了一会,结果什么也没有,就很普通。本身是打发时间的无脑小游戏,但每天时间卡得太紧,打发时间的话又重复太多(这个在同类型倒不算缺点),而且和键鼠的适配非常差,有一些很奇怪的bug,大量的行走卡顿等,但就算不考虑这些,本身大量的拖动操作也很卡手,总之就是观察增量的时候还挺舒适的,但其他的地方都有一些磕磕绊绊的小问题,目前想不到适合什么样的人群,但也不贵
