LaceFi Sleuthbox is a SQL detective game with 22+ original crime cases — murder, theft, heist, fraud, arson, cyber-sabotage, sports, school, and everyday household mysteries. Each case is a small database: you read the crime briefing, run read-only SQL queries against the evidence tables, follow the clue trail, and name the culprit. There is also a free Learn SQL tutorial and a community pipeline for submitting your own cases. Enable JavaScript to browse and play the cases.
