Get a random sudoku puzzle from the PlaySudoku.us collection.
Puzzle is returned as an 81-character string: digits 1–9 for given cells, 0 for empty cells.
The response includes the techniques required to solve the puzzle and a solve_url to the interactive solver.
Difficulties: easy (30–38 givens), medium (44–50), hard (50–55), expert (56–62), evil (56–62).
Optional: pass a technique name (e.g. "X-Wing", "Hidden Pair") to get a puzzle that specifically requires that technique — useful when the user wants to practice a particular solving method.
If no puzzle at the requested difficulty uses that technique, the error message lists which difficulties do have it.
Use solve_sudoku for a full step-by-step solution, or explain_next_step to get one hint at a time.
Every response includes a solve_url where the same puzzle can be continued in the interactive solver.
