RegexWord

Overview

Regular Expressions are a superpower for developers, but learning them usually involves boring documentation and confusing syntax.

RegexWord changes that. RegexWord turned learning into a game. By solving crossword-style puzzles where the clues are regex patterns, you'll develop a deep, intuitive understanding of how regex works—without even realizing you're studying.

Key Features

Deep Logic Puzzles

Forget simple fill-in-the-blanks. Our "Intersection Logic" puzzles require you to cross-reference row and column clues to deduce the only possible solution. It's like Sudoku for coders.

Progress through 50+ hand-crafted levels designed to take you from a complete beginner to a Regex Master.

Learn by Doing

Interactive tutorials introduce new concepts right when you need them. No long lectures—just a quick tip and a puzzle to prove you understand it.

Gamified Progress

Stay motivated with a robust achievement system. Earn badges like "The Logician" and "Grand Master" as you conquer difficult concepts.

Technical Details

RegexWord is different. I focus on Logic. You learn by deducing patterns, not by staring at flashcards. See exactly how patterns match text in a grid format. Know immediately if your logic holds up or if you need to rethink. The pattern recognition skills you build here translate directly to writing complex regex in your actual code.
