A gamified SQL challenge platform. Write real queries, beat real puzzles, climb the leaderboard — and prove you're a true data wizard.
Six tiers of increasing difficulty. Start at Rookie and progress upward — each tier unlocks only after completing all challenges in the previous one.
Story-driven SQL challenges. Solve mysteries, explore galaxies, survive dungeons — all with real SQL queries.
Powered by SQL.js — a real SQLite engine in your browser. Your queries actually execute against real datasets.
See results in milliseconds. Hints when stuck. Understand exactly why your answer is right or wrong.
Earn XP for each solved challenge. Compete on the global leaderboard and unlock adventure modes.
Detective, Space, and Dungeon modes make SQL exciting. Real narrative, real queries — not just dry exercises.
