A Doublet puzzle consists of a list of words, all of the same length. The first and last words in the list are given, and are called
Anchor Words. Each of the intervening words is defined by a clue, just as in a crossword puzzle, but in addition
it is formed from the previous word in the list by the application of one of a set of Doublet Rules.
Currently, there are three rules, giving rise to a family of three types of Doublet puzzles.
The following graphics show a Doublet puzzle in the Magnum Opus
and a PNG graphic file produced by the program's print function, showing the complete puzzle.
See also a full size version of a PDF file
showing the complete puzzle.
The key features of the Magnum Opus Doublet Construction function are as follows:-
Fully automatic construction of puzzles using anchor words ranging in number from 2 to 5.
Puzzles can be printed in an unprecedented range of user controlled colors and formats.
Output can be sent direct to the printer or, if you install the appropriate software, it can be sent to a PDF file. The
recommended software for this purpose is Primo PDF which
you can download free from their website, although you might consider sending them a small donation if
you find their program useful. Mac users will be able to create a PDF file directly from the screen provided by
the printer driver.
A fully interactive Solve function is available to allow you to solve the puzzles "on screen"
without needing to print them.
