The 42 Puzzle, as it appeared on pages 80 and 81 of The Illustrated Hitchhiker's Guide to the Galaxy

The 42 Puzzle is a game devised by Douglas Adams in 1994 for his popular The Hitchhiker's Guide to the Galaxy series. In the books, 42 is known as The Answer to the Ultimate Question of Life, the Universe, and Everything that Deep Thought, a sophisticated computer constructed by pandimensional beings, returns (after seven-and-a-half million years of calculating). Referencing this, he created a puzzle whose question was unknown, but whose answer is already known to be 42. Image File history File links This is the 42 puzzle, taken from http://www. ...

The puzzle is an illustration consisting of 42 multi-coloured balls, in 7 columns and 6 rows. According to Douglas Adams (in an interview reprinted at Douglas Adams Continuum), "Everybody was looking for hidden meanings and puzzles and significances in what I had written (like 'is it significant that 6 * 9 is 42 in base 13?'. As if.) So I thought that just for a change I would actually construct a puzzle and see how many people solved. Of course, nobody paid it any attention. I think that's terribly significant."


The puzzle first appeared in The Illustrated Hitchhiker's Guide to the Galaxy. It was later incorporated into the covers of all five reprinted "Hitchhiker's" novels.

Solutions to the Puzzle

In another interview, the author mentioned that there were 10 solutions to the problem, some of which are:

  • There are 6 rows which, multiplied by 7 columns, gives a total of 42 spheres.
  • The white globe on the left, with a bar code on it, is 42 using Interleaved 2 of 5 encoding.
  • All 6 lines of the diagram can be read as "0101010", which is 42 in binary code, if one considers the red hued spheres (red, purple, dark yellow, and black) as a '1' and those without (white, blue, green, light yellow) as a '0'.
  • If the reader looks at the spheres with a blue tint (blue, green, purple, and black), they spell '42' (in a manner similar to a test for colorblindness).
  • The Earth-coloured sphere is in the bottom right corner, the 42nd position on the grid.
  • The spheres with a yellow tint (yellow, dark yellow, green and black) spell out "XLII", 42 in Roman numerals, across the top three rows.
  • The Earth-coloured sphere appears to be centered on Latitude 0° and Longitude -42°
  • The light is shinning on the shperes at a 42 degree angle.

The Answer to Life, the Universe, and Everything - Wikipedia, the free encyclopedia (1270 words)
Later in the series, it is revealed that the Vogons had been hired to destroy the Earth by a consortium of philosophers and psychiatrists who feared for the loss of their jobs when the meaning of life became common knowledge.
It was later pointed out by readers that 6 × 9 = 42 if the calculations are performed in base 13, not base 10.
Prak confirms that 42 is indeed the answer to the ultimate question of life, the universe and everything, but reveals that it is impossible for both the ultimate answer and the ultimate question to be known about the same universe.
