Beholder presents PLANETARIUM
a puzzle story


A girl with complete foresight but no recollection of the past receives a love-letter from beyond the end of her future. Guided by her friend the mathemagician, she begins a journey through the events which his calculations have predicted and her intuition has foreseen, towards the source of the curious letter.

Each instalment contains three puzzles — usually one riddle, one number problem and one tricky puzzle — whose answers themselves form an overall puzzle, which can only be solved when the whole of Planetarium has been completed.

There are no clues to the puzzle hidden on this site outside of the story. Planetarium is a puzzle, not a trick. However, if you are seriously attempting the puzzle, it's worth looking at the FAQ and glossary — especially the bit about no plurals.

Planetarium is a work of fiction, and any resemblance to characters living or dead is entirely coincidental.
