Schema Defender
Tetris-style data quality. Rows fall from the top. Send valid rows to silver (←), invalid rows to the DLQ (→). Three mistakes and you lose.
An arcade take on the Data Quality Platform idea. Falling rows of JSON, a schema in the sidebar, and a quick decision: pass or fail. Speed-up every three correct decisions. Three mistakes and the game ends.
The fun part is also the lesson — the rules look simple in the schema panel, but at speed your eyes start missing the type mismatch on user_id or the country code being three letters instead of two. That’s exactly why the production version of this game runs as a platform, not a person.
