Hi there people.
Up for a real challenge?
Visit [Edited by Pappocom]
You will need:
1. Acrobat reader (free at adobe.com)
2. To read the instructions
3. Java Runtime Environment (free at java.com)
Basically, you need to fill in all rows, columns, boxes AND hyperboxes.
N.B. A hyperbx is a set of cells whose relative positions within their box is the same.
Good luck!
