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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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!

Enjoying the game a lot. I already know a bit of sql so I was able to make use of it. The game really makes you think to figure out the case.
Wunderschönes Spiel. Sonst bin ich nur in Action basierten Games unterwegs und hätte mir sowas vermutlich nie geholt. Aber die Kombination aus SQL und Detektiv spielen... Diese Quality die in diesem CopOS steckt.... Herrlich für eigentlich jeden. Ich stecke noch in Kapitel 5 fest, aber bestimmt nicht mehr lange. Meiner Meinung nach könnte das Manual etwas mehr <3 bzw "Erklärungen für Dummies" bekommen.

Probably more like being a real detective than most detective games where you walk around with a gun and a magnifying glass. You don't have to know SQL to enjoy this, the game holds your hand as it gives you examples of what to do. You then have to figure out how to swap out the info you are working with for the info in the examples. Seems easy but requires lots of thinking and some logic. Very rewarding when you figure it out without having to ask for suggestions from the game.
Very good game, teaches the basics functions for sql. Hilarious and instigating.
Muito legal, mas nn consegui terminar o capitulo da morte da criança no joguinho, esse capitulo foge muito da proposta de aprender SQL e vira uma jogo de puzzle somente, é legal, mas achei essa fase em especifica exagerada nesse quesito. De resto, nada a criticar, jogo muito legal e divertido, além de ser muito bem feito.
Much more engaging than I expected! Everything is explained well and the complexity increases at a satisfying rate. It never feels frustrating or overly difficult, but it is challenging enough that you have to actually think things through.
This is one of the best detective games I've played and I am hoping more content/second version of this to come.

Satisfying and hillarious puzzles. I love a game that shows dictators can be good. Zoran even banned lung cancer and crime! Zoran had absolutely no involvement in whatever happened in Yargoslavia in 1993.
