Must-Have Generator Features Explained

1. Grid Size Flexibility

Different audiences need different difficulty levels:

• Kids (ages 6-8): 10x10 grids, horizontal/vertical words only
• Adults (easy): 15x15 grids, horizontal/vertical/diagonal
• Adults (hard): 20x20+ grids, backward words, dense letter placement

Generator must allow easy toggling between sizes—ideally per-puzzle basis for variety in single book.

2. Answer Key Automation

Creating 100 answer key pages manually = 5-10 extra hours. Generator should auto-generate solution pages with highlighted word locations. Place at end of book for customer convenience.

3. Word List Management

Best generators offer:

• CSV import: Upload 500-word theme lists in seconds
• Pre-made themes: Animals, countries, food, professions (saves research time)
• Random word selection: Generate varied puzzles from same word pool
• Word length filters: Exclude very short (<4 letters) or very long (>12 letters) words

Common Generator Mistakes to Avoid

1. Using Generators Without Commercial Licenses

Some free tools prohibit commercial use. Read Terms of Service. KDP books = commercial use. Violating terms can get your Amazon account suspended. Invest in tools with explicit commercial rights.

2. Not Checking Print Quality Before Publishing

Generated puzzles may look great on screen but print poorly:

• Font too small: Elderly readers can't see 8pt letters
• Lines too thin: Grid lines disappear when printed
• Low DPI: Fuzzy/pixelated output

Always order KDP proof copy before going live.

3. Repetitive Puzzle Layouts

Weak generators produce nearly identical puzzle structures (same word placement patterns). Customers notice by page 20. Choose tools with randomization algorithms that create truly varied puzzles.
