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 Sep 11 → 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.

Cute idea, but does an exceptionally poor job of demonstrating the principles it's trying to teach and frequently leaves out tools that'd make things substantially easier in the name of faux replayability, resulting in a game best played while ignoring its unhelpful "helpful tips" and just looking at a regex command list on a 2nd monitor. Pity!
「与えられたテキストを正規表現で置換して目的のテキストにする」っていう、 システムエンジニアをやってる身としては、ゲームなの?仕事じゃなくて?…みたいなゲームです。 基本的なゲームルールは以上の通りで、 これだけだと "テキストが用意されているだけやん!" となりますが、 ・置換数、文字数や使える文字に縛りのある問題がある ・各問題で、置換数や文字数がカウントされ、それによって評価(星:1~3つ)が変わる という2点がゲームとして成立しているシステムになります。 より少ない置換数・文字数でテキストを生成することで、 その問題の解放の評価が良くなります。 また、昨今のパズルゲーム(例えば、Opus Magnum)らしく、 他プレイヤーの分布が出るため、星3つ取っても、 "もっと少なく!もっと少なく!"と熱くなれる要素があります。 前々から正規表現で遊び散らかすゲームが欲しかったので、 個人的にはドハマりですが、一般的にはどうなんでしょうね…。 べた褒めできない部分としては、 (よく確認しない私も悪いですが)ゲームを閉じるのと間違えてデータリセットしちゃったり、 過去のリザルトの確認がちょっと面倒だったりと、 UIがちょっと微妙だなと感じることがあるところです。 目は瞑れます。

These little puzzles are repetitive just enough to finally cement regex into my head. This is mindlessly chill, perfect for having to work on a holiday. Need to learn regex? Might as well make it enjoyable.
Sadly Im also agreeing with bad reviews here. Great potential. Fails to deliver the lesson before it gives you puzzle. Every regex rule should have one lesson and then it can also dive into some tricks to ease the work, but it is not doing much. The star system is badly implemented, it demotivates. while, similar to Zachtronics, its giving a graph, which would be on its own enough to hint that perhaps robust solution could be polished. Im so so sad this didnt work as I imagined it would.
Regex made fun. Well, maybe, not quite, but very entertaining and can play and, genuinely learn something useful.
I have no clue what I should do. Totally lost!
Recommendation: Not Recommended I bought "Copy Editor" hoping to get better at practical, real-world Regex, but I have ended up incredibly frustrated by the game's artificial throttling. Instead of letting you solve text challenges using standard, elegant, and efficient Regex patterns, the game constantly locks basic syntax elements (like the * or ? quantifiers, or $1 backreferences in the replace field). While the developer likely intended this to create iterative "puzzles," the actual result is that it forces more knowledgeable developers to write four or five fragile, brute-force rules to do a job that a single, standard Regex rule would solve instantly. It doesn't teach you how to write good, efficient Regex—it teaches you how to write clumsy workarounds to satisfy an artificial game engine. If you want a puzzle game that very slowly iterates over logical puzzles using Regex characters as a skin, you might enjoy this. But if you are actually trying to learn practical Regex to use in your day-to-day work, this game will only slow you down, frustrate you and teach you bad habits.
可以多放点教程吗QAQ,每关我都是网上查半天文档才能写出符合要求的表达式
Es gibt keine Tutorials oder Einsteiger Zeugs. Genauso wie keine Lautstärke Regelung oder sonstige advanced einstell Möglichkeiten. Es läuft so ab: spiel Start das was ich habe und das, was er wieder haben will. sonnst ist da nicht viel Nützliches. Ich habe erhofft, dass das spiel, mir etwas mit RegEx hilft, weil ich da ein kompletter noob drin bin aber da hilft simples Trial-and-Error mehr als das Game. Sorry, dass ich so eine negative Bewertung abgebe aber, dass musste sein
It's pretty good. Haven't gotten to the complicated stuff yet. I like using regex but have to relearn it every time I need it. Having the target text in front of you offloads some of the brain capacity needed to solve problems with regex, so you can just concentrate on solutions. You can also highlight all the parts your rule is changing, which makes it more fun to optimize.
