SQL Arcade: learn SQL from zero

Every ship is a row. Every shot is a real SQL query.

SQL Arcade is a tiny retro shooter for learning SQL from zero. Build a query by tapping tiles (SELECT, WHERE, AND, OR, =, <>) and fire: only the rows that match your WHERE go down. Hit an innocent and you lose a life.

• 3 worlds, 12 levels, 3 bosses: SELECT and WHERE, GROUP BY and HAVING, JOIN and LEFT JOIN
• The queries run for real in your browser (DuckDB), nothing to install
• No typing: works on a phone
• Stars for clean runs, combos, a hi-score, and the classic traps (= NULL, AND vs OR, double quotes)

The game counts anonymous events (level reached, no personal data) to know where people get stuck.

Cada nave es una fila. Cada disparo, una consulta SQL de verdad. Arcade retro para aprender SQL desde cero: armas la consulta con fichas y disparas; sólo caen las filas que cumplen tu WHERE. Tres mundos, doce niveles, tres jefes. Sin teclear: se juega en el teléfono. Está en español: el juego elige el idioma de tu navegador (o cámbialo abajo). El juego completo: Caso Abierto.
