Every year, a famous French youtuber (e-penser) presents his enigma of April Fool, but this year, targeting specifically a group of people who have done particularly well last year, he raised the difficulty. Maybe too much. We are about fifty people on discord to seek every day but we do not advance any more. So I share this enigma to see if we are the only ones to be able to draw anything from it.

Here is the list of proven things:

  • The image has only two colors, black and white
  • The image measures 7000x600px and the fact that it gives us 42 is intentional
  • The image is called "avril.gif", but that does not mean anything.
  • Metadatas are useless

Any help and advancement would be of great help to us.

    $\begingroup$ The coordinates of the lines, the obvious ones, and the not obvious ones, might be useful. $\endgroup$

    $\begingroup$ Also, I guess this is the same thing as boards.4channel.org/sci/thread/10515522/crack-this - which appears to be the original form of the puzzle. $\endgroup$

    $\begingroup$ We already have the coordinates of the lines and the rectangles but we don't know what to do with them. And the 4chan thread was posted by a friend who also works on this enigma $\endgroup$ Apr 5, 2019 at 18:04

    $\begingroup$ @Brandon_J Maybe. The OP gives the impression that the question here is being asked on behalf of everyone who's trying to solve it; if that's the case then I think the obvious problem with ongoing contests doesn't really arise. $\endgroup$

    $\begingroup$ Yes the story is real and Gareth is right : there's no contest, we all tried to solve this together $\endgroup$ Apr 6, 2019 at 1:04
