## Overview

Fetch, render, and reveal Sudoku puzzles. Use `sudoku.py` to get new puzzles from `sudokuonline.io`, generate printable PDFs or images, and reveal solutions.

## Get a Puzzle

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

```bash
./sudoku.py get kids6
```

## Render Puzzle

**Render latest puzzle as A4 PDF (for printing):**
```bash
./sudoku.py render --pdf
```

**Render latest puzzle as clean PNG (for viewing):**
```bash
./sudoku.py render
```

**Render a specific previous puzzle by short ID:**
```bash
./sudoku.py render --id a09f3680
```

## Reveal Solution

**Reveal full solution as printable PDF:**
```bash
./sudoku.py reveal --pdf
```

**Reveal full solution as PNG image:**
```bash
./sudoku.py reveal
```

**Reveal a single cell (row 3, column 7):**
```bash
./sudoku.py reveal --cell 3 7
```

**Reveal a specific 3x3 box (index 5):**
```bash
./sudoku.py reveal --box 5
