REAL SQL, NOT A SIMULATION
Every query runs against an actual embedded SQLite engine. Syntax errors are real syntax errors. Nothing is faked for the story.
MYSTERY, THEN RESTORATION
Season one investigates a conspiracy using SELECT and JOIN. Season two lets you fix what it broke — real UPDATE, INSERT, and DELETE.
HINTS THAT DON'T HAND OVER ANSWERS
Three tiers per case, revealed one at a time, plus a full field manual you can check any time without penalty.
LEADERBOARD & COMPARE
Track cases solved, hints used, and time taken. Compare your solving path with anyone else who's cracked the same case.
