Progress updates when you confirm that you ran and checked the SQL in DB Fiddle. Results are not sent back to Crack SQL.
Choose a domain and level above, then generate a fresh scenario from validated templates and the existing sample data.

Loading today’s challenge…
Explain your approach in your own words, as if you were telling a colleague how to solve it.
Write your complete reasoning first, then select Check My Thinking. The score checks the requested result, relevant data, solution steps and a result check. It is not an AI judgement.
Score: requested result 2 · relevant data 2 · reasoning steps 4 · checking the result 2.
Your thinking score is ready. Generate the reference SQL, then open DB Fiddle to run and test it.
Your reasoning covers the key points. Here is one reference query for this scenario:
Copy the scenario data and SQL into DB Fiddle to run and validate your answer.
Select PostgreSQL in DB Fiddle. Paste the copied schema + data into its schema pane, then paste the SQL into its query pane and run it. DB Fiddle's results stay there and are not sent back to this app.
If the new tab did not open, open DB Fiddle here.
This is one reference approach; other correct SQL solutions may also work.
