SQL Shadow : Learn SQL

🔍 Learn SQL by solving real detective mysteries.

SQL Shadow is a story-driven SQL learning game where you play a detective solving cases by writing real SQL queries — not simulations, not flashcards. Every SELECT, JOIN, WHERE, and ORDER BY statement you write runs against an actual SQLite database on your device.

🕵️ SOLVE REAL CASES
Investigate a growing set of hand-crafted noir mysteries — from your first SELECT statement to multi-table JOINs, aggregation, and filtering with GROUP BY and HAVING. Talk to suspects, gather evidence, and write real SQL queries to uncover the truth. New cases are added regularly, each one built to teach a specific SQL concept as you go.

📚 LEARN SQL STEP BY STEP
Short, focused lessons cover the fundamentals before every case — SELECT, WHERE filtering, JOINs, wildcards, aggregation, and more — so you're never guessing what to type.

🎮 PRACTICE WITH MINI GAMES
Sharpen your skills with 450+ questions across three game modes: SQL Quiz, Spot the Wrong Query, and Fill the Gaps — at Beginner, Intermediate, and Advanced difficulty.

📰 THE DAILY DETECTIVE
A newspaper that updates as you play — dev updates, top-detective shoutouts, and behind-the-scenes notes, so there's always something new to check.
