There are two halves to a Pyramidwprd puzzle, with each half consisting of a series of words of increasing length.
Each word is an anagram of the previous smaller word plus one additional letter. For example:-
IN NIB BINS BINDS SINBAD DISBAND SIDEBAND
A clue accompanies each word so that the puzzle can be solved in the same way as a crossword puzzle.
These graphics show a Pyramidword puzzle in the Magnum Opus
and a PNG graphic file produced by the program's print function, showing the complete puzzle solution.
