In 2003, it became an
International Society, (re)founded by Peter Bentley and Albert Frank.
The goal of the society is - without any exception - to
present BEAUTIFUL puzzles.
The members must of course specify if they are the
author of the puzzle, or give the origin. A puzzle may never come from a (active
or inactive) test.
Besides, the puzzles may not be cultural, may not be
related to a language (some members don't speak English), and must not need high
academic knowledge.
