*Insert Clever Title Here*

I'm proud of this puzzle I made today.

A small one to keep you guys occupied.

Yeah, I'm still here. WARNING: The Loop-de-Loop is quite challenging for its size. I do not recommend it to beginners. :)



I have a HUGE backlog of solutions to check. I'll see if I can get to it.

This one's a smorgasbord of stuff.


Enjoy solving, and send your solutions to the address on my info page. :)

This puzzle is dedicated to Zotmeister, who turns 30 today (well, in his Rhode Island timezone, anyway). If it weren't for him, I would never have learned how fun pure logic can be. And then this blog wouldn't exist! :)


See, I have baked two cakes for you, one to celebrate your 30th year, and one to celebrate your upcoming 30th puzzle, which I look forward to eagerly. (Clearly, the cake on top is a pineapple upside-down cake. :))
The color is there for aesthetics only; it can be ignored for solving purposes. If you'd prefer a standard black-and-white version of the puzzle, click here.

Send your solutions to my e-mail address. I especially look forward to Zotmiester's reaction to this puzzle. =D

Here are two more Loop-de-Loops I made recently. The first one has symmetric givens, which required a lot of strategizing to achieve; the other one is just HUGE. Enjoy, and send your solutions to my usual e-mail address. :)

Here's another Loop-De-Loop puzzle which ought to interest veterans of other logic puzzles. Read the following lj-cut to see more info:

Here's another big Loop-de-Loop. But remember, just because it's big does not necessarily mean it's hard. :)

ANOTHER Loop-De-Loop! I hope you like this kind of puzzle. :)

Another puzzle that's been sitting on my pad of graph paper waiting to be rendered as an image. It's also big, so here's a thumbnail which links to a full-sized image:

A VERY special thanks to Zotmeister, who pointed out that this kind of puzzle is possible by my new rules. Re-read the rules, and keep in mind that the loop may ONLY turn where a dot is present, and that the white and black circle parts of rule 4 refer to dots and not spaces.



Solutions, comments, and PayPal donations may be sent to gbf87ATcoxDOTnet, as per usual.

The puzzle is kinda huge, so click the thumbnail to view it.

This is my version of another puzzle from Zotmeister's blog. This one is a semi-original creation of Zotmeister; it combines elements from several other popular puzzles, including Masyu and Slither Link.



Puzzle on left, solution on right. Rules:
1. Draw a single loop that connects the square "dots" on the grid. The loop may only travel horizontally or vertically, and never diagonally (so all turns are of 90 degrees). The loop may only turn at the dots. The loop may not cross itself or branch off. In other words, the interior of the loop will be a single polygon.
2. All edges shown in the grid must be incorporated into the loop.
3. All numbers inside the grid indicate how many of the four edges of the imaginary square surrounding the number are in the loop.
4. Some of the dots have symbols in them which dictate how the loop may travel.
Concentric squares: The loop MUST pass through this dot.
White (open) circle: The loop MUST pass through this dot. Additionally, the loop MAY NOT turn at a white circle, but MUST turn at ONE or BOTH of the adjacent dots on the loop.
Black (filled) circle: The loop MUST pass through this dot. Additionally, the loop MUST turn at a black circle, but MAY NOT turn at EITHER of the adjacent dots on the loop.
Circle with a slash through it: The loop MAY NOT pass through this dot.



This puzzle isn't terribly difficult, but hopefully it is fun to solve. It is demonstrative of the aesthetics that a good puzzle designer can work into such a puzzle. (Whether or not I actually am a good puzzle designer is up to you. :))
