## Description
_+=3: A Controversial but Nevertheless Logical Adventure_ is an interactive
fiction game, written as a counter-example to a claim made on the
rec.arts.int-fiction newsgroup that “there could be no puzzles which are
logical yet unsolvable”. The game essentially has one puzzle, but one that –
as the authors believe – is practically impossible to solve despite making
perfect logical sense.
The player takes control of an adventurer who has already solved all the
puzzles in the game, and now faces one last challenge, a “Three Troll”
guarding a bridge. In the player’s inventory is a “qualitative calculator”,
and the player also knows that “something is ticking” in the vicinity. The
goal is to get past the troll.
