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.
Same day: best AU #89, worst UK #97 · 2 markets collected
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): 5/day in the week to Sep 11 → 24.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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

There’s been a backlog of unsolved cases piling up in the Minor Crimes Division of the Los Zorangeles Police Department and we’ll need a Database Detective to help solve them.
We’ll need you to analyze clues and manipulate data using SQL, a database querying language, to figure out who perpetrated crimes from as minor as littering to as serious as not checking out of a hotel after the check-out time.

Don’t worry! This role is intended to be accessible for those without any SQL experience, so each Database Detective is given an introductory textbook when they start! This short textbook is less than 20 pages and explains everything that’s needed to solve each case.
If you still have trouble writing queries, our comprehensive error messaging system will tell you exactly where your query went wrong, making it easy to correct your mistakes.
Still not enough? Each Database Detective is assigned an assistant who’s ready to answer any questions you might have, whether they be about the case itself or the SQL queries you’ll need to write!


Understanding how to manipulate data using SQL is not the only part of being a Database Detective! Your job will also require you to piece together evidence and clues, just like a real detective! Further on in your Database Detective career, you’ll have to sleuth through the internet and piece cases together yourself.
Fully voice acted mission briefings at the beginning of each case!
Fully hand drawn art for you to enjoy!
More than 40 websites to explore!
10 cases for you to solve, each case getting longer and more complex!
A total of around 8-10 hours of valuable work experience to add to your resume!

Excellent game, I have a lot of fun playing it. I hope there will be more cases
Muito divertido apesar de ser difícil depois da metade, vale a pena mesmo se for jogar só pelos puzzles. Legal para relembrar sobre SQL

If you like SQL and puzzles, this is the game for you!
Lovely game, full of funny little details that help to keep the queries going
Very fun!
No pase del 5 caso. Obra maestra.
I feel like I'm not the audience for this game. I cleared 4 chapters, but I constantly have to go back into the book and remember what to type and how to type and it's a lot of going back and forth. I feel like I'm not learning about how the game works as much as taking an open-book test which is frustrating. By chapter 5 of the "war crime" story, I understand the end goal, but not the process of getting there. And if I can't understand basic mechanics of a game by part 5 I know I'm cooked.
Игра отличная, я системный аналитик по профессии и с огромным удовольствием использовала конструкции, которые редко нужны в работе. Я бы рекомендовала ее всем своим коллегам! Захватывающий сюжет, который не ожидаешь от симулятора SQL, с продуманной альтернативной вселенной, очень затягивает. Видно, что игра сделана с душой и очень много продумано нюансов, браво разработчику! Чудесное приключение)
lo compre para practicar, pero SQLazo que se carga el jefe no me deja concentrarme xd
[h1]SQL 玩法很棒, copOS 交互很烂!3 / 5 ⭐⭐⭐☆ ☆[/h1] [h2]关于 copOS[/h2] 桌面大小是局促的 文件排列是平铺的(没有文件夹!) 窗口数量是有限的 浏览器是没有 Tab 的(只能开四个!) 记事本每页居然真的只有一页纸长度! [h2]关于 SQL 窗口[/h2] 没有自动补全(??!!) 同时只能开启一个 SQL 窗口 [h2]我的一点建议[/h2] 在 copOS 上,使用 SQL 作为[b]唯一[/b]的推理工具,有点太难了。如果能再给个全局的字符串检索工具(grep),多是一件美事啊! [b]等等,好像有人在敲门,我去去就回……[/b]
