Three posts, five rings, endless possibilities…

I’ve always been a big fan of DIY puzzling. With seven nieces and nephews to keep engaged and entertained at family gatherings, I often find myself cobbling together new games and puzzles for them from whatever I can find around me.

(For instance, you’d be surprised how many board games are spiced up a bit by the addition of dinosaur figurines.)

So last weekend, I discovered my youngest nieces have three of those ring-stacking toys with the colored rings, the ones I think every kid has played with at some point or another.

And I realized I had all the tools necessary to whip up a challenge for the kids and adults alike… a Tower of Hanoi puzzle.

The Tower of Hanoi puzzle and its many variants look simple, but can be fiendishly puzzling. The rules are simple: move the stack of rings from the first post to the third. You move one ring at a time, and at no point can you place a larger ring atop a smaller ring.

(The standard puzzle is five rings, but variants can go as high as 10.)

I gave the adults first crack at it, and after laughing it off as childishly simple, it took them far longer than expected to solve the puzzle, especially in the later stages as you try to place the largest ring. There was plenty of pointing and strategy and “No, no, not there! THERE!”

The kids, on the other hand, worked together, and managed to solve the puzzle in about fifteen minutes, each taking turns moving colored rings here and there (and for my youngest niece, occasionally biting them, as you do). Their sense of accomplishment was a joy to watch, and each crowed to their parents about their victory.

As a placement puzzle, the Tower of Hanoi is much like a sudoku puzzle, a combination of strategy — where to place a number or a ring — and deduction — determining which moves you can’t make based on the information provided. It’s one of those universal puzzle-solving skills that will serve a puzzle fiend well for decades to come.

Big things brewing at PuzzleNation!

Sudoku: Every number in its place.

Sudoku puzzles are as ubiquitous as reality shows these days, and enthusiastic solvers can find puzzles of nearly any difficulty with ease.

Sudoku puzzles are usually ranked from one to five stars, with five star puzzles being the most difficult. Difficulty can depend not only on the number of starting digits, but their placement and the level of deduction involved.

Sudoku enthusiasts were the first to notice that the lowest number of clues required for a unique solution is 17. Puzzles with 16 clues invariably had alternate solutions.

For comparison purposes, the average newspaper sudoku has 25 set numbers. The sudoku puzzles on PuzzleNation vary in difficulty, but our easy puzzles range from 30 to 36 clues and our expert puzzles range from 25 to 30 clues, with medium and hard puzzles clue counts falling in between.

But the 17-clue threshold was all conjecture until a mathematician from University College Dublin named Gary McGuire put in the time (and the computer processing power) to write a mathematical proof confirming the suspicions of sudoku enthusiasts.

He designed a specific computer algorithm to process various sudoku grid patterns, allowing him to cut down on the computing time necessary to verify his conjecture. (Even with the reduced computing time, it took 7 million CPU hours in total, a monumental amount of processing time.)

From the nature.com article:

The idea behind this was to search for what he calls unavoidable sets, or arrangements of numbers within the completed puzzle that are interchangeable and so could result in multiple solutions. To prevent the unavoidable sets from causing multiple solutions, the clues must overlap, or ‘hit’, the unavoidable sets. Once the unavoidable sets are found, it is a much smaller—although still non-trivial—computing task to show that no 16-clue puzzle can hit them all.

Of course, as I said before, difficulty isn’t just about the number of clues. The puzzle widely regarded as the world’s hardest sudoku puzzle has 21 clues, but their placement makes for a much more mentally-taxing solving exercise.

I guess it just goes to show the old real estate cliche is true: it’s all about location, location, location.

How did you get into puzzling?

More than a few people have asked me how I became a puzzler. What strange, meandering road led me to the hallowed halls of puzzlesmithery? Could aspiring puzzlers follow the same path to puzzlewonderful adventures?

There’s no single path to puzzlerhood. Sure, there are some fairly universal commonalities. Do you have a great vocabulary? Mad trivia skills? Are you a whiz with palindromes, anagrams, or other forms of wordplay? These can all help. Also, a background or degree in English doesn’t hurt.

But every puzzler I know took a different route. It’s not as if we all one day awoke to a knock at the door, only to discover a small basket left on the doorstep, and tiny elfin footprints leading back toward the enchanted forest down the street.

Though, admittedly, that would have been awesome.

Here, let me take you through some of the highlights in my puzzle resume, and we’ll see if my experiences offer some guidance or inspiration for those with puzzletastic aspirations.

Unrecognized Wheel of Fortune Grand Champion, USA, 1988-present

Since I was about seven years old, family members have called me into the family room to see who can puzzle out the quotes, phrases, and punny answers behind the lovely Vanna White, and I regularly school both contestants and kin with ease. While Mr. Sajak refuses to recognize my two decade reign as Wheel of Fortune Grand Champion (Stay-at-Home Division), that doesn’t make it any less noteworthy.

Internship with the Riddler, Gotham City, 2000-2001

There are few puzzle personalities in the world with the flair, cachet, and renown of Edward Nigma, otherwise known as freelance detective and occasional criminal mastermind The Riddler. So when I had the opportunity to sit in with him and learn from his decades of riddle-centric shenaniganry, I leapt at the chance.

I studied the intricacies of mechanical puzzles, wordplay, and punsmithery while under Nigma’s wing, and although I frequently found myself in legal and moral gray areas — and on the receiving end of more than a few POW!s and BIFF!s — the experience was well worth it.

Tetris Foreign Exchange Program, St. Petersberg, 2002

There’s no better spacial awareness training than Tetris — I can feng shui the packages in the back of a UPS truck like nobody’s business, and don’t get me started on my legendary vacation-packing skills — and with the addition of that horrendous tension-inducing “you’re near the top!” music, I’m cool as Siberia under pressure.

Puzzle Summit with Will Shortz, New York City, 2007

Okay, it wasn’t so much a historic meeting-of-the-minds as it was me yelling puzzle ideas at him with a megaphone as I chased him down the street. But that totally counts.

Freelance Puzzle Historian, Self-Appointed, USA, 2009-present

Oh yes, puzzle history is a rich and varied field of study, one to which I have devoted a great deal of time and effort, unearthing some fascinating and surprising discoveries. For instance, did you know that Nero did not, in fact, fiddle while Rome burned? He was far too busy being frustrated by the extreme Sudoku puzzle he’d picked up in the marketplace.

PuzzleNation Citizen, PuzzleNation, 2011-present

Yes, I was granted full citizenship in PuzzleNation, with all rights and responsibilities that entails. (Like walking the Diggin’ Words dogs and such.)

Well, there you have it. A brief glimpse in my particular puzzle experiences and how they’ve shaped me. Here’s hoping you can blaze your own puzzlerific trail, be it through decoding Linear B with Cryptogram-ingrained proficiency or anagramming your friends’ names to your heart’s content.

Good luck, and in the meantime, keep calm, puzzle on, and I’ll catch you next time.

Puzzled what to get someone for Christmas?

The holiday season is upon us, and with Black Friday and Cyber Monday already making way for Thoroughly-Frustrated Shopper Thursday, I’d be remiss if I didn’t offer up some puzzly suggestions for holiday gifts.

As you might expect, I come from a puzzly family. So Christmas has always featured brain-teasing toys, 3-D puzzles, and whatever else parents and other relatives could find to keep us busy and baffled. My younger sister has passed this tradition on to the next generation with puzzle boxes for my nephews, ensuring that any holiday money is well earned by mid-afternoon.

Here are a few ideas for the puzzle lovers in your life.

For any Rubik’s Cube masters in your household, Eric suggests a marvelous variation with The Brain Cube. Instead of matching colors, you’re matching the geography of the brain, ensuring that each fold and wrinkle lines up with its neighbors. This is a real brain-teaser, available at Marbles — The Brain Store.

We’ve featured ThinkFun products on the blog before — most notably their puzzly day-to-day calendar — but that’s just the tip of the iceberg. They’ve got puzzle games and brain-teasers galore, suitable for all ages and levels of difficulty. (This hexagon one caught my eye while I was browsing.)

The folks at Hammacher Schlemmer offer all sorts of gadgetry and products, and two of them caught my eye as I perused their catalog for gift ideas.

The first was the maze bank pictured above, The Labyrinthine Piggy Bank. Any coins that fall off the track are safe and secure, but only someone with the patience and dexterity to navigate the ten feet of track within will be able to gain access!

The second piqued my interest as a lover of words and wordplay. It’s The Lexicographer’s Extended Scrabble game, a 21×21 grid with more tiles and squares than the original, allowing for more flexibility and more elaborate words. Perfect for the verbivore Scrabble enthusiast in your life.

If you’re looking for pen-and-paper puzzle goodness, our pals at PennyPress and Dell Magazines offer perfect stocking stuffers, as well as digest-sized and full-sized puzzle books. Whether it’s logic, crosswords, word seeks, fill-ins, sudoku, variety puzzles, or the Brain Boosters shown above, they’ve got you covered.

And, of course, you can’t go wrong with a one-year PuzzleNation gift subscription! With access to ten different puzzle games, as well as score tracking and two-player mode to solve with friends,  hours of puzzle-solving fun await.

This is just a small sampling of the puzzle-wonderful delights available this holiday season, but hopefully these suggestions will help you trim down your shopping list this year. So good luck, keep calm, puzzle on, and I’ll catch you next time.
