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.

It is such a fun and cute little game! It’s really relaxing and perfect when you just want to switch your brain off and do something satisfying for a while. The daily gameplay loop can start to feel a little repetitive. You’re doing the same general routine of mining, refining and selling each day, which is perfectly okay since that’s the whole mechanic. However, I think it would be really fun if the refining process varied a little more from gem to gem. That being said, for the price point, I think this is a fantastic game and definitely worth picking up if you’re looking for something chill and relaxing.
I'm 15 hours in and despite not loving it in the beginning, now that I've got some solid upgrades under my belt I'm hooked in. I love that there are options to adjust the loan shark's intensity and to make the chisel game simpler (it's fine for me on the gems but for some reason the artifacts mess me up) and it's super nice you don't have to restart the whole game when you make adjustments. The art style of this game is adorable, I'd buy plushies of any and all of these characters. It is grindy, but the upgrades actually matter and they feel worth achieving. Personally a big fan of the speed boost. I can't really afford anything in the Bazaar yet, but I'm excited to cute up Grandmole's home. Speaking of! I like the storyline with her and the relationship between her and Moel. This game is definitely worth a try, and if you're frustrated in the start remember to check the upgrades. I cannot stress enough that they're so worth it and they make the game so much more enjoyable.

I enjoy the relaxing nature of owning a cute little shop to sell gems out of. I personally really enjoy gems and rocks so this is perfect for me. There is also the option for a slower pace without deadlines if you prefer to not have a timer.
Cute, Cozy, Gem
不好玩,挖矿和打磨的设计都很不上心很无聊,人物只有4个面甚至没斜面,手感和指引奇差不如rpgmaker,打磨更是糟糕得非常无聊,说是增量目前看起来一眼就看得到头,喜欢这个题材的还不如随便打开抖音一个鉴宝小游戏
its super cute
玩法挺有意思的,但是感觉玩久了有点单调
Sí buscas relajarte mientras escuchas un poco de musica, y quieres ser un topo donde solo debes pulir gemas hasta pagar la deuda de tu abuela en definitiva es tu juego, no es complejo
Gemporium is a cozy mining and shop-management sim where you play as a mole running your Grandmole's gem shop while trying to pay off the $1 million debt she left behind. You mine gems, refine and polish them, sell them to customers, and upgrade your tools and shop as the days go on. Pros ✔️ The core loop keeps building - Mining gems, polishing them, selling them and putting that money into upgrades already works well, but new tools and systems keep adding a little more to the routine instead of leaving you doing the exact same thing all game. ✔️ The Twitch integration fits really well - Viewers can show up as customers and leave messages, which works naturally with the shop instead of feeling like a random streaming feature slapped on top. ✔️ It stays cozy without removing the goals - You have deadlines, upgrades to work toward and Grandma's absolutely terrible financial decisions hanging over you, but I never found it overwhelmingly stressful. Cons ❌ Early debt payments should count for more - If I pay extra toward the debt ahead of schedule, I would like that to lower the minimum I still owe at the deadline instead of basically having both payments expected from me. ❌ Mining needs a better explanation - It took me longer than it should have to understand where I was supposed to hit around a gem and how to get it out without cracking it. ❌ Opening the shop locks up too much of the day - I would rather sell everything, close the shop while there is still time left, and go back to polishing gems or doing other jobs before deciding when I am actually done for the day. Conclusion By around ten days in I had settled pretty comfortably into Gemporium and could see why this routine could carry a much longer playthrough. It is very cute and fun, and there is something weirdly motivating about slowly improving your tiny gem business because Grandma apparently decided a million dollars of debt was also part of the inheritance. Score 7.5/10 Precious Gems - 2.5 of them cracked.
Cute little game, but don't let the aesthetics fool you! It wants you to play at break-neck speeds. It's a bit short, I finished the main "story" after 5 hours and could have probably done it an hour sooner. But for the price I paid for it (5€) its well worth it. I wish there was more to everything, because the gameplay loop is satisfying.
