                   PUZZLEMAKER - Paul Stephens 

                   http://www.puzzlemaker.com/

Forms for creating ten computer-generated puzzles linked to 
solutions on the Web: 

 - Mazes
     choose from a variety of shapes and path patterns, and 
     set the dimensions

 - Number Blocks
     create a block of numbers where each row, column and 
     diagonal add up to a total, but some numbers remain to 
     be filled in

 - Math Square
     specify the range of numbers that will uniquely satisfy 
     a grid with arithmetic operations and end totals already 
     filled in

Other puzzles include:

 - Double Puzzle (two-level word scramble)
 - Criss-Cross Puzzle (crossword)
 - Word Search
 - Word Search with a Hidden Message
 - Cryptograms
 - Letter Tiles (unscrambling letter tiles to rebuild 
     a phrase)
 - Fallen Phrase (unscrambling phrases one row at a time)

In addition to computer-generated puzzles, the author
displays unique hand-drawn mazes by artist Tesseract.
The site also features documentation of the ActiveX objects
and the Virtual Basic software used to create the puzzles, 
and a FAQ that includes instructions for saving and/or
transferring puzzles to a word processor.
