{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"How do these story-driven SQL games teach SQL?","acceptedAnswer":{"@type":"Answer","text":"SqlInt's SQL puzzle games teach SQL through stories: investigate crimes, recover ancient artifacts, and save civilizations using nothing but queries. Each story runs on real PostgreSQL inside your browser — read the chapter, write SQL, run it, and unlock the next twist. Start free with no signup, from your first SELECT to window functions and CTEs."}},{"@type":"Question","name":"Are these SQL games really free?","acceptedAnswer":{"@type":"Answer","text":"Yes. Every SQL puzzle story starts free with no signup — you can read the story, see the schema, and try the first chapters in your browser. Advanced stories and later chapters are part of the paid challenge packs."}},{"@type":"Question","name":"Do I need an account to play SQL puzzles?","acceptedAnswer":{"@type":"Answer","text":"No account is needed to browse every puzzle story and preview its schema. A free account is required to run queries and save progress; logging in keeps your solved chapters synced across devices."}},{"@type":"Question","name":"Which SQL dialect do the puzzles use?","acceptedAnswer":{"@type":"Answer","text":"Real PostgreSQL, running entirely in your browser via PGlite — no server, no setup. The JOIN, CTE, window-function, and subquery skills you learn transfer directly to SQLite, MySQL, and SQL Server."}},{"@type":"Question","name":"Can beginners learn SQL through these games?","acceptedAnswer":{"@type":"Answer","text":"Yes — that is what they are built for. Stories start with basic SELECT and WHERE and progress chapter by chapter to JOINs, aggregations, CTEs, and window functions, each with hints. If you prefer a structured curriculum first, start with the Learn SQL Roadmap, then come back and play."}},{"@type":"Question","name":"How are SQL puzzles different from SQL interview questions?","acceptedAnswer":{"@type":"Answer","text":"Puzzles teach SQL through story-driven games where each chapter builds on the last — ideal for learning SQL from scratch. Interview questions are standalone real-world problems for practice and preparation. Many learners play a puzzle story first, then drill the interview question bank."}},{"@type":"Question","name":"Is my progress saved?","acceptedAnswer":{"@type":"Answer","text":"Yes. Once you are logged in, solved chapters and attempts are saved to your account automatically, so you can switch devices and continue the story where you left off."}}]}
