The latest addition to my puzzle menagerie is STAR BATTLE, a newish (well, 21st century, at least) puzzle that was originally created by Hans Eendebak for the 2003 World Puzzle Championship. If you like Suguru you will probably find these fairly easy to get into, as they are somewhat similar. But instead of placing numbers, […]

I get a lot of requests for new puzzle varieties (all different kinds) but I started getting a lot of requests for one particular puzzle the past couple of years. I didn’t notice at first, because the different requesters were using different names: Binairo, Tic-tac-logic, Binoxxo, Binario, (I later discovered it is also called Takuzo, […]

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 […]

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, […]

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. […]

Hey 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 […]

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 […]

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 […]

There’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 […]
