Puzzle 284: Room and Reason 19

Remember my cover version of the song "7 Joyful Automatons" that I keep promoting? Don't worry, I promise that this will be the last time I promote it. For behold, the puzzle below contains a 7. Additionally, it has seven other numbered rooms, and seven unnumbered rooms. Last, but not at all least, the puzzle is pretty easy, just like how the aforementioned song is calm and easy to listen to. There is truly no better way to pay tribute to the song using a puzzle. :)

Puzzle 283: Polyominous 30

Foggy Brume said that my previous puzzle "looks a little too much like a swastika", and not enough like 7's. Well, as I said in the comments, the puzzle wasn't intended to look like 7's, but was retroactively deemed to "kinda look like 7's" when I wanted to post a puzzle in honor of my cover version of the song "7 Joyful Automatons", and was too lazy to actually make a new puzzle. However, I'm less lazy now. Behold, six 7's, and not a swastika in sight. It would have been nice to have seven 7's, but for obvious reasons involving my insistence on arranging the givens symmetrically and the asymmetry of the digit 7, this couldn't have been done. (For similar reasons, half of the 7's are upside down.) Oh, and the largest number in the puzzle is 7, too. Hope you're happy, Foggy! :) ;) But seriously. . . enjoy this puzzle.

Puzzle 282: Fencing Match 31

As some of you may already know and care about (or maybe even know and not care about), I am a creator of NES chiptunes. Yesterday, I created a cover version of "7 Joyful Automatons", a song originally composed by an individual who calls himself Oren Otter. Then I got a crazy idea to make a puzzle themed around the number 7, and post it with a link to the song. But then I found this puzzle I made about three weeks ago, and thought, "Hey, those kinda look like 7's. Yeah, let's go with that." Please feel free enjoy this puzzle and the aforementioned song -- possibly at the same time. :)

Logicsmith Exhibition 3: Polyominous

Would you like to try your hand at logicsmithing, and possibly be featured on my blog? Read on!

In an intriguing experiment on its online puzzle site nikoli.com, the Japanese company Nikoli asked its authors to create different Slitherlink puzzles all using the same arrangement of givens. More recently, they asked its authors to create different Akari puzzles all using the same arrangement of black cells. I've decided to try a similar experiment here, using the puzzle Polyominous (link to rules, Polyominous puzzles from my blog). Your challenge is to replace each of the question marks in the grid below with an integer to create a uniquely solvable Polyominous puzzle.
Send your puzzle (and optionally, its solution) to my e-mail address at glmathgrant@gmail.com. After three weeks (meaning the deadline is September 7), I will post the puzzles that my readers and I have constructed for this layout. Good luck, and have fun!

Puzzle 275: Tetra Firma 18

275! It's a number! It's a big number! And it's the number of this puzzle, which is a big puzzle!

Normally, when I decide I want to post a huge 31x45 puzzle on my blog to celebrate some milestone like 275, I have the puzzle made many days, if not weeks, in advance of actually reaching that number of puzzles. However, in this instance, I didn't even decide I would have a giant puzzle for 275 until last night. The initial construction was done in about three and a quarter hours; it took about half an hour more to create the image, after which I went to bed. Vetting the puzzle and fixing a mistake I found took about three hours. My brain is now kind of throbbing from all of those hours -- I hope you're happy!

By the way, if you happen to find some regions in the grid that are shaped like digits, such as, say, I dunno, 2, 7, and 5. . . that's just a total coincidence.

Puzzle 270: Reunion Tour 3

This puzzle is a prime example of why Nikoli discourages Numberlink solvers from trying to be too logical, and encourages a healthy dose of "inspired guessing". This, of course, doesn't make things easier on the constructor, who must make sure that only one solution exists for each puzzle. I suspect that my solvers will have a much easier time with this puzzle than I did. *laughs*

Rules -- Reunion Tour

AKA Numberlink.


1. Draw paths that connect the pairs of identical numbers on the grid. The paths may only travel horizontally or vertically, and never diagonally (so all turns are of 90 degrees). The paths may only turn at the centers of cells.
2. The paths may not cross each other, pass through other numbers, or otherwise share cells.
