Crossword Generator (requires membership)

What You’ll Create:

  • Themed crossword puzzle books (10-130+ puzzles)
  • Professional PDF output ready for Amazon KDP
  • Each puzzle has a unique theme/category
  • High-quality, creative clues (not generic AI templates)

Time Required: 2-4 hours for a 50-puzzle book

Tools Needed:

  • Claude.ai account (free or paid)
  • Our Crossword Generator (download from PublishPuzzles.com)
  • Excel or Google Sheets (for converting files)

Part 1: Generate Your Word Lists with Claude.ai

Step 1: Understanding the Batch System

To create quality crossword clues at scale, you’ll generate your word lists in batches. Each batch contains 6 themed sub-categories with 75 words each (450 words per batch).

Why batches?

  • Claude.ai has context limits – smaller batches maintain quality
  • Easier to review and fix any issues
  • Better organization

How many batches do you need?

  • 10 puzzles = 2 batches
  • 20 puzzles = 4 batches
  • 50 puzzles = 9 batches
  • 130 puzzles = 22 batches

Step 2: Copy the Batch Prompt

Use this prompt in Claude.ai. Replace the sub-categories with your chosen themes for each batch:

Create 75 crossword entries for EACH of these 6 sub-categories (450 total entries):

BATCH [NUMBER] SUB-CATEGORIES:
1. [Main Category]|[Sub-Category Name]
2. [Main Category]|[Sub-Category Name]
3. [Main Category]|[Sub-Category Name]
4. [Main Category]|[Sub-Category Name]
5. [Main Category]|[Sub-Category Name]
6. [Main Category]|[Sub-Category Name]

CRITICAL FORMAT REQUIREMENTS:

**Output Format:**
MAIN_CATEGORY|SUB_CATEGORY|WORD|HINT

**Delimiter:** 
- Use the PIPE character | as the delimiter (NOT commas)
- The pipe is the vertical bar: |
- Example: Art & Design|Abstract Art|CUBISM|Picasso's geometric style

**File Structure:**
- First line must be header: MAIN_CATEGORY|SUB_CATEGORY|WORD|HINT
- Each following line: one entry with 4 fields separated by pipes
- Hints CAN contain commas freely (they're safe because we're using pipes)

**Words:**
- 3-15 letters, single words only (no spaces, hyphens)
- Words CAN repeat across different sub-categories with different hints
- Each sub-category needs EXACTLY 75 unique words

**Hints - BE CREATIVE AND VARIED:**

Use DIVERSE clue styles. Mix these approaches throughout:

1. **Literary/Cultural References:**
   - "According to Gertrude Stein, a ___ is a ___ is a ___"
   - "The flower in Beauty and the Beast's glass dome"

2. **Wordplay & Puns:**
   - "Card game that rhymes with smoker"
   - "Instrument that's also a fish, plays in the bass section"

3. **Definitions with Flair:**
   - "Thorny symbol of romance, often red on Valentine's Day"

4. **Fill-in-the-Blank:**
   - "Compass _____, navigation diagram showing directions"

5. **Trivia & Facts:**
   - "Only fruit with seeds on the outside"

6. **Pop Culture:**
   - "Shark species featured in Jaws"

7. **Rhymes & Alliteration:**
   - "Shrub that blooms, adding color to garden rooms"

8. **Question Format:**
   - "What do bees collect from flowers?"

9. **Comparisons & Metaphors:**
   - "Like a sunflower's face, it follows the sun's daily race"

10. **Historical/Etymology:**
    - "Named after Turkish headwear, this spring bulb blooms"

**VARIETY IS KEY:**
- No two consecutive clues should use the same structure
- Alternate between short (5-10 words) and longer (15-30 words) clues
- Mix obvious and challenging clues
- NEVER use generic phrases like "related to," "associated with"
- NEVER use templates like "A [category] that [description]"

**Example Output:**
MAIN_CATEGORY|SUB_CATEGORY|WORD|HINT
Art & Design|Abstract Art|CUBISM|Picasso's revolutionary style that shattered objects into geometric fragments
Art & Design|Famous Painters|MONET|Claude who painted water lilies obsessively in his Giverny garden
Board Games & Puzzles|Card Games|POKER|Game where a royal flush beats a full house

Generate all 450 entries now (75 for each of the 6 sub-categories listed above).

Step 3: Example Batch Breakdown

Here’s how to organize your batches. Customize these to your book’s theme!

BATCH 1 (Art, Games, Finance):

  1. Art & Design|Abstract Art
  2. Art & Design|Famous Painters
  3. Art & Design|Sculpture & Statues
  4. Board Games & Puzzles|Card Games
  5. Board Games & Puzzles|Chess Terms
  6. Board Games & Puzzles|Strategy Games

BATCH 2 (Games, Finance, Nature):

  1. Board Games & Puzzles|Party Games
  2. Board Games & Puzzles|Dice Games
  3. Finance & Business|Banking Terms
  4. Finance & Business|Stock Market
  5. Flowers & Plants|Spring Blooms
  6. Flowers & Plants|Roses & Thorny Plants

Continue this pattern until you have all your desired sub-categories.

Step 4: Generate Each Batch

Important: Use a FRESH chat for each batch!

  1. Open Claude.ai
  2. Paste your customized batch prompt
  3. Wait for Claude to generate all 450 entries
  4. Copy the entire output (including the header line)
  5. Save to a text file named Batch_01.txt (or similar)
  6. CLOSE that chat and start a NEW one for the next batch
  7. Repeat for all batches

Pro Tip: Don’t try to generate multiple batches in one chat – quality degrades!

Part 2: Convert Excel to Pipe-Delimited CSV

Claude.ai will likely give you the output in a table or you’ll copy it to Excel. You MUST convert to pipe-delimited format.

Method 1: Using Excel/Google Sheets

If Claude gives you a table:

  1. Copy Claude’s output
  2. Paste into Excel or Google Sheets
  3. Save/Download as CSV

Then convert the CSV:

Option A – Find & Replace in a Text Editor:

  1. Open the CSV in Notepad, VS Code, or any text editor
  2. Find: , (comma)
  3. Replace with: | (pipe)
  4. Save as Batch_01.csv

Option B – Using Excel Formula:

  1. In Excel, create a new column
  2. Use formula: =SUBSTITUTE(SUBSTITUTE(A1,",","|"),CHAR(10),"")
  3. Copy the entire formatted column
  4. Paste as plain text into a new text file
  5. Save as Batch_01.csv

Option B – Request Pipe Format from Claude: At the end of your generation request, add:

When complete, output ONLY the raw pipe-delimited text (not a table).

Method 2: Verify Your Format

Open your CSV file in a text editor. It should look like this:

MAIN_CATEGORY|SUB_CATEGORY|WORD|HINT
Art & Design|Abstract Art|CUBISM|Picasso's revolutionary style
Art & Design|Abstract Art|MONDRIAN|Dutch painter with primary colored grids
Geography & Travel|World Cities|PARIS|City of Love where Eiffel Tower stands

✓ Correct: Pipes (|) separating the 4 columns ✗ Wrong: Commas separating columns (commas should only appear INSIDE hints)

Troubleshooting Common Issues

“Duplicate in category” warnings

Fix: Review your CSV file and remove duplicate words within each sub-category

“Word in hint” warnings

Cause: The answer word appears in the clue
Fix: Uncheck these entries or edit the hint in your CSV

“Puzzles have too many black squares”

Cause: Not enough words or words don’t intersect well
Fix:

  • Increase “Target Words Per Puzzle”
  • Make sure you have 70-75 words per category
  • Check that words have common letters (E, R, S, T, A, I, N, O)

“Only generated X puzzles instead of Y”

Cause: Not enough categories in your files
Fix: Each sub-category = 1 puzzle. Need 50 sub-categories for 50 puzzles.

“CSV won’t upload or parse errors”

Cause: Wrong delimiter (commas instead of pipes)
Fix: Open CSV in text editor and verify pipes (|) are used
