Table Editor – best for larger lists, CSV import, and detailed editing.

Step 2 – Add Your Words and Clues

In the textbox, type one word per line.
To add a clue, use a dash - or colon : after the word.
Example lines:
- SUN - Star at the center of our solar system
- MOUNTAIN: Tall natural elevation
- RIVER (no clue – the tool will mark it as “(no clue provided)”)

Option B: Table Editor

Switch to Table Editor.
Click + Add Row to add a word.
Type your word in the Word column (letters only; spaces and symbols are removed).
Type your clue in the Clue column (optional).
Use the ✖ button to remove any row you don’t need.

The tool generates short, generic clues for any empty clue cells.
Review and edit these clues as needed before generating the crossword.

Step 5 – Set Date, Difficulty & Grid Size

Difficulty – choose your own level or leave it on Auto and let the generator estimate difficulty.
Grid Size – choose a grid size (e.g. 10×10, 12×12, 15×15). Larger grids fit more / longer words.

Tip: If your longest word is too long for the selected grid, the tool will warn you so you can pick a bigger grid or shorten the word.

Click Generate Crossword.
The tool:
- Lays out the words on the grid
- Adds black squares where needed
- Numbers the starting squares
- Splits your clues into Across and Down with word lengths (e.g. (7)).

Step 7 – Show or Hide the Solution

Use the Show Solution / Hide Solution button above the grid:
- Show Solution – reveals all letters on the grid.
- Hide Solution – hides letters again, leaving a blank student-style grid.

This toggle is just for your on-screen view; exports handle student/teacher modes automatically.
