I happened to meet one of my friends after about a couple of years. Obviously we both were very happy, but still, she didn't leave her habit of challenging me to decipher what she was saying. I thought that again she'll give me some seemingly random characters to search for some meaning; but she didn't.

Instead she started drawing some boxes on the ground, which turned out to be two 5x5 grids, and yes there was a number in each cell too. This was what it looked like:

Obviously I couldn't decipher at that time what in this world she was trying to say, so I just clicked the photograph, and continued with the rest of our talks. And yes, she said that it is more of a visual puzzle.

All this happened some time back, but today I found that photo again, and as usual I didn't know what it meant.

What in this world was she trying to say?

By the way, this is a direct hint to this puzzle.

    $\begingroup$ Is the cell in the second grid (col 4, row 5) supposed to just show half of two? $\endgroup$ – Elpharya Mar 20 at 18:56

    $\begingroup$ @Elpharya It is supposed to show the complete "2". Thanks, I'll update the picture. $\endgroup$ – Eagle Mar 20 at 18:59

She's saying

"HI"

The puzzle is

A Pair of Slitherlinks

  • $\begingroup$ +1, but note that the solution is far from unique, you can basically do whatever you like in the middle and then fill out the exterior accordingly. $\endgroup$ – Arnaud Mortier Mar 20 at 21:04
  • $\begingroup$ That's the right answer! Maybe you should try the puzzle linked in the question? I think it'll be very easy now. $\endgroup$ – Eagle Mar 21 at 3:24
  • $\begingroup$ @ArnaudMortier Are you sure? Slitherlink has specific rules - you have to form a single loop without crossings or branches. I tried the puzzle and there is only one solution. I'd like to see a counterexample if you have one. Unless you mean multiple solutions to the puzzle itself, assuming it's NOT slitherlink, then, of course, all bets are off... $\endgroup$ – Amorydai Mar 21 at 18:41
  • $\begingroup$ @Amorydai I was not aware of the closed loop condition. Thanks. $\endgroup$ – Arnaud Mortier Mar 21 at 18:42
