Theme: Birthday Mystery

Author/Opus: This is the 108th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Draw a single loop of horizontal and vertical segments that passes through all of the white cells (and only the white cells) exactly once. Like last week’s puzzles, there is also a second puzzle style that this grid can be solved as. Doing so will help you find a secret answer word.

• James McGowan says:

Very nice, thanks!

• Jack Bross says:

Happy Birthday, Grant and very nice seeing both puzzle styles come together for the finale.

• skynet says:

What other puzzle genre is hidden in here?Can someone post the spoiler ?I tried solving this as a Uvgbev and the puzzle breaks down no later than just a few steps.

• Jack Bross says:

There’s a clue near the bottom of the puzzle…

• skynet says:

Thank you .I understood what you alluded

• Francis says:

I saw the same clue but it took me a little while to believe that was the correct puzzle type because I’m used to it having ertvbaf orfvqrf ebjf naq pbyhzaf.

• drsudoku says:

Formally, this is more of a “Onggyrfgne”. I commented to Grant several times throughout the longer than usual puzzle approval process here that he was probably wrong to think many people would know that variation even if we have posted it once before.

• Bryce Herdt says:

I got WANDER, but I think that was by starting in the wrong place. >u<

• skynet says:

WANDER??I am getting PLANETSHK ,HELP TASK N and so on…Just don’t understand what is to be done here after solving it as a Fgne Onggyr

• Scott Handelman says:

The puzzles work together in the final step.

• skynet says:

Thank you..Got it at the last!

I love this site and all the different puzzle types, but I have no idea what is going on here. Could someone please tell me what are the rules? I don’t think I have ever seen anything like this before.

Also, I realize that some commenters are using a replacement cipher. Is it a different key every time? I cannot figure out what some of you are saying. Sorry, I’m feeling very frustrated.

• drsudoku says:

Everyone uses a rot13 cipher here (take each letter to its inverse in the alphabet). I recommend you just copy the phrases to this site to get a few hints/spoilers.

• Grant Fikes says:

You don’t take each letter to its inverse; that’s atbash!

• drsudoku says:

I guess I’ve learned to view the alphabet as a circle because of years spent with secret decoder rings and cryptexes.
