Books, books and more books

February 22nd, 2018

I started publishing print-on-demand puzzle books a few months ago, and I’m now up to 22 books. Yay! The latest are four volumes of Killer Sudoku, available in Large Print and 4-per-page. The most popular, at the moment, are the “Tough Kakuro” and the “Stupendous Suguru” books.

The easiest way to find my books is to search for “Krazydad” on Amazon.

If you think I’m getting rich from my burgeoning publishing empire, you would be wrong! I make a few dollars per book, and I’m selling about a book a day, which is keeping me in coffee, but not exactly paying for my dog’s chiropractor. If you’d like to help me work my way up to TWO cups of coffee, you can help by reviewing my books (honestly) after you buy them. Thanks!

The print-on-demand company I’m using is CreateSpace which is owned by Amazon. There are rumors that CreateSpace might get merged into Amazon’s very similar KDP (Kindle Direct Publishing) service. If/when this happens, it may affect the availability of my books for a short time, but they should reappear. My reason for not initially publishing on KDP is that it requires that the book be made available in digital form for the Kindle. Since my books require pencils/pens, they need to be on paper, not Kindles. I wouldn’t want Kindle owners buying virtual versions of my books only to be disappointed, and leaving bad reviews.

If you’re curious how this whole self-publishing thing works, and want more gory details, I’m happy to share – just contact me via email.

Topple puzzle magazine

December 19th, 2017

Looking for a little more variety in your daily puzzle consumption?

Gregory Gray wrote to tell me about his indie puzzle magazine, Topple. Each issue costs a buck to download and print yourself, and there is a very wide variety of puzzles, many with illustrations which remind me a bit of the Sam Loyd Cyclopedia, if you know what that is.

Greg is currently up to Issue #7, as of this writing. The latest issue contains 16 puzzles, of which four are Nikoli style puzzles (Masyu, Hashi, Nurikabe, Kakuro) and the others are from further afield. I very much like the anagram ring puzzle shown here.

Here’s a sampler that Greg sent me.

And here’s the website where you can get more!

Where are the logic puzzles?

June 22nd, 2017

I sometimes get emails that ask where the logic puzzles are. “I thought your site had logic puzzles, where are the logic puzzles?” they ask.

My site does indeed have logic puzzles, by which I mean puzzles in which you employ logic to solve them. Pretty much every puzzle on my site meets this description. However, I’m being pedantic. I believe the logic puzzles being referred to by my correspondents are the kind that involve a group of girl scouts, sitting at a counter in a Boba shop, each with a different skill badge, a different pet, and a different beverage:

The 7 year old sits on a red stool.
The 8 year old has a schnauzer.
The 9 year old is drinking a green tea boba.
The green stool is just to the left of the white one.
The girl on the green stool is drinking a mocha boba.
The girl with the computer-expert badge has a one-legged parrot.
The girl on the yellow stool has a dancer badge.
The girl in the center is drinking a strawberry boba.
The 11 year old is on the first stool.
The girl with the hiking badge is next to the girl with an ocelot.
The girl with the pottery badge is drinking taro boba.
The girl with the magical pony is next to the dancer
The 12 year old has a home scientist badge.
The 11 year old is next to the girl on the blue stool.
The hiker is next to the girl drinking a plain tea boba.
Who’s got the Ferret?

Although these are commonly called logic puzzles, I prefer to call them “logic word puzzles”, since there are all kinds of puzzles that employ logic, not just these. I’ve also seen them called Einstein’s Puzzle, also a terrible name.

Whatever they are called, I don’t carry them. This is because of those pesky words. In order to produce them, I would have to come up with 4-6 lists of related things (girl scouts, boba beverages, sweaters, mood-rings, troll figurines, etc.) for each individual puzzle, and this would be extremely labor-intensive, especially since I like to put out many thousands of each puzzle variety, so you don’t run out.

This website currently has over a million puzzles on it, and the reason there are so many is because I’m able to use power tools (namely, computer programming) to produce them. I’ve thought about combining various word lists in combinatorial ways to produce these puzzles, but I don’t think the results would be very appealing (there are five girl scouts, each has a favorite muscle car, lives on a different planet, and has a different number of legs). Probably the best solution would be for me to crowd-source the word lists. The idea being that you, the visitors to this website, could suggest lists of things to use in puzzles), but setting this up would also be very time consuming, and would probably require moderation so as not to be abused by spammers and trolls.

For similar reasons, I don’t carry Fill-a-pix, Mosaik, Connect-the-dots, and other puzzles that employ unique pictures for the solutions, not to mention Word-Search and Crosswords. If you want to set up a moderated crowd-sourcing system for word-puzzle and picture-puzzle content that I can use, let me know when it’s running! I’d love to use it!

Krazydad books are coming!

March 1st, 2017

Suguru Book CoverHey folks, I’m currently working on a series of puzzle books which will be available on CreateSpace and Amazon, starting sometime in March, 2017. [ UPDATE: They’re available! ]

I’m starting with a Suguru collection. Each Suguru book contains 300 puzzles and is priced at $9. The puzzles in the books are all new, and do not appear on the website. Learning how to self-publish has been (and will continue to be) an interesting journey. I had a lot of fun figuring out how to make a book cover that uses the Droste effect.

After Suguru I’ll be working on books of Kakuro, Krypto Kakuro, Killer Sudoku and more. If there’s a particular puzzle variety you’d really like to see in book form, let me know!

I’d love to include a variety of short testimonials from actual Krazydad visitors, like yourself, on the back cover. If you’d like to submit a short testimonial, drop me an email with the subject line “Krazydad Testimonial”, and let me know how I should credit you (e.g. “Jane from Pittsburgh”). By sending the email, you are tacitly agreeing to let me publish your testimonial on one or more back covers.

Also, if you’d like to receive (very occasional) announcements by email, when I publish new books, let me know!

Thanks so much!

UPDATE: My first Kakuro books are now available on CreateSpace.

UPDATE: My first volumes of Easy and Challenging Suguru puzzles are now available on the CreateSpace store, as well as on Amazon. Enjoy!

Through the Looking Glass

February 28th, 2017

Part 7. Through the Looking Glass

This is one of a series of posts about my health/fitness journey. The first one is here.

It’s been a while since I’ve written one of these, so here’s a quick update. It’s late February, 2017. I’ve been hovering around 180 pounds (plus or minus 3 pounds) since early November, last year. This is a good thing in that I’ve been able to maintain a healthy weight for several months, and I’m not experiencing diet fatigue (a big problem for me the last time I made it down this far). I’d like to be a few pounds lighter, but I’m very happy with the weight I’m at, especially considering I was at 245 a year ago.

I’m the most fit I’ve been in, well, ever. Certainly since I was in my early 20s, and even then I never exercised. Now I’m going to the gym 4-6 days a week, and I can see the effects in the mirror.

Alice through the looking glassWhen I was a kid, I was fascinated with mirrors. We had a big floor-to-ceiling mirror in our living room, when I was growing up, and I liked to play with it. Early on I discovered the trick of making spiders or crabs, by sticking my hand out on the edge of the mirror, and exploiting the symmetry. A friend and I would stand on opposite ends of the mirrors in department stores, bisecting our bodies as evenly as possible to make it look like we had three legs, or were floating in the air.

And very early on, I discovered some of the laws of mirrors. For example, I noticed that if you looked at someone’s reflection in the eyes, then they would see that your reflection was making eye-contact with them. And the corollary of that: if you can see someone’s eyes in a mirror, then they can see you.

I remember looking in the mirror at the age of six or seven, and imagining what my future adult self would look like. I imagined an older single man, with the same bowl haircut and bangs, his house filled with boxes of the froot loops my mom wouldn’t buy (too much sugar!). As I grew into my adolescence, and got more into music, I would look in the mirror and imagine my future album covers, posing as a serious brooding rock star.

I found mirrors more troublesome in my twenties. I remember a Mexican restaurant near my work that had a wall of mirrors. I found that if I sat facing the mirrors, it was difficult for me to concentrate on what my colleagues were saying, because I would be distracted by my reflection. I learned to sit with my back to the mirror.

And as I continued to age, that distraction became more unpleasant. I stopped wearing bangs pretty quick, and pretty soon, by my early 30s, I lost a lot of my hair. My dreams of being a cereal-eating guy with bangs were dashed! The slight double-chin I had developed in my late teens became more and more pronounced, and I grew a beard to cover it. As I grew into my thirties, forties and fifties, the act of looking at myself for long periods in the mirror became a distant memory. The occasional Hitchcockian glimpses of the mirror became almost frightening – reminders that I wasn’t the abstract cereal-eating child in my head, but a physical creature, mortal, fat and frail.

It had been so long since I was at a healthy weight that I thought I had created a permanent condition. The fat on my belly had become a big hard slab. The idea of reversing or easing my condition seemed like an insurmountable wall. At 53, I thought I had probably abused my body so much, that I was basically done; just watching the clock until the end. Of course, I didn’t allow myself to think about this very much; I spent most of my time (as I still do) “in my head”. But, I was far more distressed than I allowed myself to realize.

And of course, there was that whole “endomorph” thing. Based on my conversations with others, and my reading, I had classified myself as an “endomorph”. It was the equivalent of Cartman on South Park insisting he is “big boned”. I was endomorphic, that’s the body type I had, and there was no changing it. I wished I was an ectomorph, but you get the genes you’re dealt, or so I thought.

So now, I can say, with the benefit of hindsight, that the whole endomorph/ectomorph thing is pure and utter bullshit. When I first met a nutritionist I was working with, last year, she told me confidently I was an endomorph. A few months and about 30 pounds later, I asked her, “if I came in for the first time today, what would you classify me as?” “A mesomorph” she said.

So was I fat mesomorph? Am I now a skinny endomorph? No. I reject the whole notion. To paraphrase Popeye, I yam what I yam (which is mostly yams, if it’s Thanksgiving).

If you have only a passing familiarity with the terms ectomorph, endomorph, and mesomorph. I suggest you read the wikipedia article about William Herbert Sheldon, the doctor who invented “somatotypology” back in the 1940s. He published volumes of nude photographs of young men and women, with very precise descriptions of their body types, and it is very clear, from reading his actual work (I bought his 1954 book “The Atlas of Men” on EBay) that the guy was an utter quack. It is also quite possible, by the way, that nude photos of Bill and Hillary Clinton are included in his photos of Yale students which are sealed at the Smithsonian!.

While it might be useful to use somatotypological language to discuss the state that a body happens to be in at the moment these terms should definitely not be used to describe a permanent state-of-being from you which cannot recover. Any health professional who casually uses those terms to describe you is participating in a form of pseudo-science, not much different than astrology or phrenology.

So at the moment, I look at the mirror again, after all these years, without fear or disgust. I can see that I am not an endomorph, ectomorph or mesomorph. I am me. It is certainly clear that I have some issues which are different than you, different than some of my skinny friends who seem to be able to consume vast quantities of beer and fried foods. My issues aren’t really with my body type. They are with my relationship with food. I know that if there is a plate of cookies in the house, I am going to be thinking about that plate of cookies, nearly continuously until the plate of cookies is gone. I know that if I have a plate of food in front of me, I’m going to finish it. Those issues are pretty much the same as they were a year ago. What is different is how actively I am working to prevent those issues from running me into the ground.

My frequent visits to the gym are a huge part of this. Let’s be clear: the exercise is not having much of an effect on my weight loss. I cannot lose weight simply by exercising more. But it has a massive effect on my energy levels, my positive outlook, and my muscle tone. I have regained some of the narcissism of my youth, actually enjoying periodically gazing at my biceps in the mirror, trying on clothes, looking at them — something I thought I would never do.

And I’ll allow myself a little narcissism at this point. I’ve been on the other side of the mirror.

An advanced Kakuro technique

January 18th, 2017

I got a letter a few days ago, asking for help with a particularly intractable Kakuro puzzle: 8×8, Volume 14, Book 99, Puzzle #8. Since my Kakuro puzzles are arranged by difficulty, this is a particularly hard one, since it is in Book 99. Here you can see where the solver got stuck:

I was able to make a little progress using an advanced technique I call “Implicit pairs”. Take a look at the 4 circled cells near the top of the puzzle.

The vertical ovals show two containers, each containing a pair of cells, with the clues 13 and 11. The top horizontal oval is also a 2-cell container, with the clue 16. The bottom horizontal oval is around a pair of cells which are part of a much longer container.

Because we know the 4 cells sum to 13+11, we can work out the sum for the bottom two cells. It must be 13+11-16, or 8. So we can treat the bottom two cells as an “implicit pair” which sums to 8. Since it sums to 8, we can see that we can’t use the 4s, because 8 = 4+4, and this would cause a duplicate number. So we can eliminate the 4s, and this enables us to solve the four cells.

Are you stuck on a Krazydad puzzle? Send me a snapshot and I’ll try to help!

Happy puzzling!

Serpentomino Puzzles for Christmas

December 13th, 2016

Sample Serpentomino SolutionThere’s a snake in my inbox!

Bulgarian puzzle constructor Galen Ivanov sent me two collections of interesting new puzzles, Serpentominos, of his own design, which I’m passing on to you, as a Krazydad Christmas present. These puzzles share some characteristics with Pentominos, Dominos and similar mathematical recreations, and are quite different from the Sudoku and Slitherlink variant puzzles you may be used to.

As the illustration shows, you fill the grid with line segments, completely filling the grid with 13 “serpents” – each of which occupies 6 squares, and begins and ends on one of the provided dots. Serpents may not cross or touch each other. No two serpents may have the same shape (including rotations and reflections), and due to the constraints of snake skeletal anatomy, no serpent’s shape may include a sharp “u turn” — you can’t make two rights in a row, or two lefts in a row.

Please reread the preceding paragraph carefully, because all the rules are absolutely necessary to solve these puzzles, otherwise you will find them impossibly maddening (as I did, before I understood the sharp u-turn rule).

Galen has provided two sets of these puzzles, small-sized puzzles, as shown here, in which you fill a grid with 13 six-block serpents, and medium-sized puzzles, in which you fill a larger grid with 30 seven-block serpents.

If you get completely stuck, send me a snapshot, and I’ll try to help you make some headway.

Weight loss recipes

December 2nd, 2016

So I’m still down about 65 pounds, currently fluctuation between 179 and 183 lbs most days. I survived Thanksgiving and my birthday, both in near proximity, gaining and losing about 4 lbs over a week. A lot of folks have asked “what plan I’m on”. I’m not really on a plan, just a system of my own reasoning: Eat fewer calories than I exert. However, there are definite trends in my dietary habits. I eat far less sugar, I don’t eat fast food, I avoid quick/easy foods, and eat a lot more fruits/vegetables. I make a lot of omelets, and I eat a lot of yogurt. There are two foods in particular that I am currently eating so often that they show up at the top of my “MyFitnessPal” lists: Protein shakes and homemade soup. I thought I’d give my approximate recipes for both.

I probably have five or more protein shakes a week. I almost always have them in the mornings after I work out. My recipe has evolved – I started out using pre-sweetened/flavored protein powder mixed with yogurt and fruit, and now I use a pure whey protein that I mix with cocoa powder, and I don’t always add yogurt. I’ve gradually been adding “superfoods”
like chia seed and hemp seed, as a way to boost certain desirable properties. I’ve replaced milk with almond/cashew milk to reduce the calories. I’ve replaced Cacao powder with Hershey’s Cocoa, which also has fewer calories. Here’s my current typical recipe:

Krazydad Protein Shake

1 scoop Whey Protein Isolate (Now Sports)
1 scoop Green Powder (Amazing Grass Green Superfood Chocolate)
* 1 Tablespoon Chia Seeds (Viva Labs)
2 Tablespoons Non-Alkalized Cocoa Powder (Hershey’s “Natural”)
2 Tablespoons Psyllium Husks (Yerba Prima)
* 2 Tablespoons Hempseed (Healthworks)
* Optional: 1 Stevia Packet (Stevia in the raw)

UPDATE: I’ve stopped using the ingredients marked with a star in recent months, mostly because I’m trying to simplify things.

All the preceding ingredients can be pre-measured and stored in baggies in the freezer.

1.5 cups Unsweetened Almond,Cashew or Coconut Milk (Almond Breeze)
2/3 cup Frozen berries/kale (Wegman’s Strawberries, Blueberries, Cherries w/ Kale) OR fresh fruit & kale.
1 cup ice

Note, all the dry ingredients are available on Amazon. I’ve put unaffiliated links on each line.

Final numbers: 513 calories, 40g carbs, 26g fat, 44g protein, 9g sugar.

I try to restrict my daily sugar to 40 grams a day, which comes out to about 13 grams of sugar a meal. So this comes in below that and gives me a few grams to play with. It is easy to exceed this number by adding a banana (which adds sugar and carbs) or other fruit (and pay for it with a lower sugar lunch or dinner). I also sometimes add a half container of plain greek yogurt, which ups the protein, and possibly the fat. If I’m working out I also add two BCAA capsules (an amino acid, which may help with muscle recovery).

The main reason I’ve stopped using pre-mixed protein powders is that they tend to contain artificial sweeteners like Sucralose which my gut objects to. I have a higher tolerance for Stevia, so I’ll use that sometimes, but not always. The longer I’ve gone without sugar, the less I crave it.

I blend my protein shakes in a Nutribullet, and have learned, through experience, to remove and clean the gasket every time. Ideally, you want to fill the container about 2/3 full – this produces a thicker shake when there is available air to make bubbles, expand and fill the container. If you fill the container with ingredients, the result is soupier and less “shake like”.

I am a chocolaholic so my recipe makes a very chocolaty shake. If you are of the vanillaholic persuasion, do your thing.

Okay, now on to the soup! I make this soup at least once a week, and it feeds the entire family one evening, and then me for another day or two.

I’ve been making all my soup in a 6 quart Instant Pot electric pressure cooker. This is super fast, compared to the traditional method, and gives the meat a great texture.

Krazydad Pressure Cooker Chicken Soup-like substance

1. Saute one chopped onion, 5 cloves chopped garlic, and chopped bulbs of 7-8 green onions.
2. Optional: Once brown, add a cup of a robust grain (Ferro, barley or brown rice) and saute it for a minute.
3. Add a 14 can of fire roasted tomatoes.
4. Add 4 cups of chicken stock or bone broth (when I make bone broth in the pressure cooker, it makes enough for two batches of soup. If you start making bone broth around 2 or 3pm, you can have soup for dinner. More recently I’ve been getting lazy and using a single 32 oz box of soup stock from the market).
5. Add a ton of chopped veggies. My veggies typically include 2 stalks celery, 2 carrots, a half or whole eggplant, a zuchini, a poblano pepper, a jalapeno, some chopped kale or spinach, mushrooms, a handful of pitted kalamata or other good olives.
6. Add 2 or 3 chicken breasts or an equivalent amount of chicken meat.
8. Dried herbs/spices (Oregano, Basil, Thyme, Roasted Cumin, Black Pepper)
9. Pressure cook for 6 minutes (it’ll take 20 minutes or so to get up to pressure), then let it sit for 10 more minutes, and release the pressure valve.
10. Remove chicken, discard bones, if any, shred the meat and add it back in.
11. Add fresh herbs (cilantro or Italian parsley) and juice of 2 limes.

My pressure cooker liner has a “don’t fill above here” line. I totally ignore this line and generally fill the pot to the top with veggies, and then cram the chicken in. It seems to work okay, as long as the fluid level isn’t above the line. The result is probably closer to a stew than a soup, and by the second day, the ferro, if added, have absorbed most of the fluid.

Pretty much all the ingredients in this soup are optional (especially the grain and the non-savory vegetables). The only thing you really need is stock and onions. I use whatever vegetables I have on hand, and try to change it up a little each time I make it. Its hard to imagine a vegetable that won’t work in this soup, although I’d be hesitant to use a lot of beets.

Sometimes it’s closer to a restaurant chicken tortilla soup (cumin/lime/avocado), and sometimes I emphasize the Italian herbs and olives. Every batch is great, but roughly every fourth batch is knock-your-socks-off great. I don’t know why but I suspect it has something to do with getting the proportion of savory ingredients right. Over time, I’ve been adding more and more green onions than I thought I originally needed, and this seems to help.

I can eat two bowls of this soup, for dinner, without too many ill effects.
