Get a Puzzle

Fetches a new puzzle and stores it as JSON. Output is JSON by default (use --text for human-readable output).

Use --count N to fetch/store multiple puzzles in one call. If a batch does not contain enough unseen puzzles, the command will fetch additional batches until it has enough.

Use --id <fragment> to select a specific source puzzle by matching any unique part of its UUID. If multiple IDs match, the command errors and lists candidates.

Get a Classic Easy puzzle:

./scripts/sudoku.py get easy9

Get multiple new puzzles at once (e.g. 4 easy 9x9):

./scripts/sudoku.py get easy9 --count 4

Get a Kids 6x6 puzzle:

./scripts/sudoku.py get kids6
