Copy Editor: A RegEx Puzzle

Copy Editor: A RegEx Puzzle is a puzzle game about using Regular Expressions (RegEx) to process and revise famous texts for demanding publishers. You use “find and replace” commands to transform input text until it matches an objective. Tutorials teach the basics, so you do not need prior experience with RegEx; the puzzles focus on tactics and lateral thinking.

Rules and obstacles

Levels can limit how many rules you use or disable particular keyboard keys. The game also extends RegEx with Natural Language Processing tools, letting you filter text by criteria such as sentiment, word stems and parts of speech.

Optimization and custom levels

You can optimize your solutions and compare your performance with others through detailed breakdowns. A level editor lets you create challenges for the community.
