Puzzle Apps I’ve Been Playing

Puzzle Apps I’ve Been Playing

After a drought of decent puzzle games for my iPad, a whole bunch of them were simultaneously brought to my attention.

G30

You know that feeling where you can’t quite think of a word you need? It’s just on the other side of a fog that seems to have coalesced inside your brain? That’s the problem faced by the protagonist of G30, except it’s not words that have been forgotten — it’s objects. On each level of this absorbing little game, you are given a target item to assemble. You start off with something that seems close to right, but isn’t quite there yet. By turning an assortment of dials, you adjust the details — changing the shape of this part or that part, or rearranging the whole — until finally you magically assemble the eyeglasses, or the file cabinet, or whatever it is you’re trying to remember.

The game quickly becomes fairly complicated, as certain dials can’t be turned until other dials are properly positioned. Turning those dials, however, might screw up the evolution of your target item. Getting to the finish line then becomes a careful, logical ordering of steps — or, quite possibly, a whole lot of random turning combined with a vague intuition of how to reach your goal.

Pavilion

A maze game in which you’re not the one running through the maze. That job has been filled by a thin man in a brown suit. He, however, is more often than not at a complete loss at how to proceed through the game’s many gorgeously detailed levels.

You’ll help him out by ringing a series of bells. When our man hears a bell, he runs toward it — climbing up and down ladders, scuttling through passageways, anything it takes to get to the source of the sound. The only thing that will stop him on his way is the ringing of another bell. That will get our friend to swerve in his tracks and head for the new ringing sound.

Figuring out the order of the bells and the timing of ringing them is a tricky but fun challenge. (I am highly adept at making the little man run in endless circles.)

Pavilion: Touch Edition by Visiontrick Media AB. $3.99.

OCO

A maze game so abstract, it doesn’t look like a maze game at all. You are nothing more than a white square, and all you can do is run and hop. Your goal: Collect all of the yellow bits on each level, and do so in the least amount of time and/or with the smallest number of hops. (On many levels, these two goals cannot be accomplished at the same time.) This is easy enough on the lower levels, but before too long it’s going to take a lot of trial and error before the correct path through the maze becomes clear.

Achromatic!

In general my feeling is, spare me from any more “minimalist” puzzle games, and yet this one sorta snagged me. You have a field of random-seeming shapes: Circles, squares, oblongs. On each turn, you’ll trace a path from two like-colored shapes, passing through an assortment of shapes of a second like-color. (So in the above example, you can draw a straight line from one dark green circle to the other, passing through the blue circle-in-a-circle. If there had been other blue shapes along the way, that’s fine, too.) The path completed, all of the shapes you touched along the way will become the color of the starting and ending shapes. (So our blue circle-in-a-circle will turn dark green.) The object of the game: Make all the shapes the same color.

Additional rules throw complications galore into the mix. Your path can only turn on a square. Oblongs can only be passed through on their long side. When that circle-in-a-circle changes color, so does all its neighbors.

Ostensibly this is a logic puzzle, but unlike a pencil-and-paper visual logic puzzle, where each step leads inexorably to the next, it’s not always easy in Achromatic to see the path to the solution — trial and error is the order of the day, and a certain amount of feeling your way along. But when you finally do see how to reach the goal, it can be pretty darn satisfying.

Achromatic! by Nick Carney. $1.99.

Typoman

A side-scrolling platform game with a wordplay twist. You’ll do the usual things one does in a game like this — run, jump, avoid monsters and obstacles — but along the way you’ll encounter various letters and words. By manipulating these, you’ll literally change your environment. (Need an obstacle to get out your way? Perhaps the word PRAISE sits nearby. Just get rid of the first letter.) A very neat twist on the dustiest of genres.

Puzzlesnacks is Live on Kickstarter!

Puzzlesnacks is Live on Kickstarter!

Yesterday I officially launched a new Kickstarter, to help me get my rebranded puzzle project off the ground. Puzzlesnacks, as of this moment, is already 89% of the way towards its goal — and it reached that level in less than a day!

I’m hoping the whole thing might get funded just over 24 hours, which would be thrilling, and then we can move on to all of the fun stretch goals: Supersized Puzzlesnacks!

So if you like the idea of quick little puzzles that aren’t too easy but also aren’t too hard, click on through. For just $3 a month, you’ll get Puzzlesnacks in your in-box every week, plus lots of bonus puzzles. Climb into the higher reward tiers and I’ll send you some (or even all!) of my books, including the first volume of Puzzlesnacks, which will be in bookstores this summer. (More about that very soon.)

Band Weaving

Band Weaving

This past weekend at the American Crossword Puzzle Tournament, Mike Shenk was honored for his long and deeply influential career in puzzles. Among his many achievements is the introduction of two mainstay variety crossword types:

  • Marching Bands, in which two words read across each row, and then also wind clockwise around each concentric band.
  • Spellweaving, in which words weave together in a dizzying diamond pattern.

Patrick Berry (an assured future honoree) made a tribute puzzle for Mike, and it is jaw-dropping. It is a Marching Bands grid AND ALSO a Spellweaving grid, overlapping significantly, so that a bunch of letters are used in both puzzles.

Those of you who solve crosswords regularly are likely familiar with the concept of “checked” and “unchecked” letters. In your typical daily crossword, every letter is “checked” — that is, it is used in an Across answer and also a Down answer. Sometimes a crossword might have an extra message appearing on the diagonal, in which case the letters in that message are “triple checked” — each one used in three times.

Most of the 35 letters in the overlap of Patrick Berry’s puzzle are QUADRUPLE CHECKED — used twice in the Marching Bands puzzle and then used twice more in the Spellweaving. That Patrick thought he could do this at all is audacious. That he succeeded as wildly as he did, making it look, as usual, like a matter of no particular consequence, is beyond bananas.

Patrick has now made the puzzle available in the Free Puzzles section of his Web site, A-Frame Games. Solve it and be amazed.

Mystery Hunt 2019

Mystery Hunt 2019

As the captain of a team of superb puzzle-solvers who theoretically do not care whether or not they win the annual MIT Mystery Hunt as long as everybody has a good time — but who, let’s face it, kinda do want to win one of these days — it is difficult not to be of two very conflicting minds about the chart you see here.

The chart was shown at this year’s wrap-up by Setec Astronomy, the team that had spent the previous year creating nearly 200 incredibly challenging puzzles and activities, which they had parceled out to thousands of solvers in Boston and around the world over the course of the weekend. Setec had earned this responsibility by winning the 2018 Mystery Hunt; the winner of their Hunt will, naturally, go on to create a Hunt of their own for 2020.

When the chart appeared on the screen, nobody on stage said anything at all. They simply displayed it and stood back. Within moments, its meaning became clear, and the groans began. Palindrome (my team) and the eventual winners, Left Out, had been neck and neck through the first thirty hours of the Hunt. And then, lo and behold, Palindrome started to pull away! We eventually would reach a thirteen puzzle lead over our closest competition… at which point we hit what I shall now call the Palindrome Plateau.

We’ve plateaued before, heaven knows, but rarely this dramatically. (Or anyway, I’ve never seen it so dramatically depicted.) Ten hours — ten solid hours — of being stuck on every single puzzle we had left. And in that same ten-hour period, Left Out never faltered — they maintained their steady pace, overcame us, and seized the day.

It’s tough to be 100% blasé about that.

And yet, my main takeaway from this year’s Hunt was how much fun I had. The structure of it was ingenious. Every Hunt has a theme, and this year we were treated to a trip through the Holiday Forest, sort of like the one Jack Skellington wanders into in A Nightmare Before Christmas. Now, normally, a Hunt is divided into specific sections, each with its own set of puzzles. Solve the puzzles, and you get a set of answers. Tie those answers together in some magical way, and you’ll have solved a metapuzzle — a major leap forward in your team’s progress. In a typical year, given a holiday-themed Hunt, you’d expect to have a bunch of Christmas puzzles and then the Christmas metapuzzle, and then Halloween puzzles followed by a Halloween metapuzzle, and so on. But the Setec folks are far more clever than that. Yes, we had Christmas puzzles and Halloween puzzles, and puzzles for plenty of other holidays besides — but to solve one of the important metapuzzles, you had to take some answers from one round and some answers from another, and you didn’t know which answers you needed and which ones you had to reserve for later. For die-hard puzzlers who have seen their share of metapuzzles, this was a delightfully crafty curveball, one that raised the trickiness factor just enough without pushing things into the red zone of impossible.

Except I didn’t solve any of the metapuzzles this year. And in fact… as I look through the long, long list of puzzles served up in the 2019 Hunt, it would seem that I didn’t solve any of those, either. Oh, I kept a hand in, don’t get me wrong. I entered information on spreadsheets. I researched things. I nailed down a few cryptic clues here and there, and my brother Dan and I even solved an entire variety crossword and discovered its secret message, which proved valuable to solving the larger puzzle that it was a part of. But at no point was I ever the person who stood up and said “The answer to this puzzle is WHATEVER!”

So why on earth do I go to this event where the puzzles are so hard that some years, like this year, I can float through the entire weekend without solving any of them?

The team, folks. That’s why. The team. I enjoy solving puzzles all by myself, heaven knows, and I enjoy going to events where I’ll co-solve puzzles with three or four friends, but there is nothing like being a part of a Mystery Hunt team. It’s the difference between a solo violin player, a lovely string quartet… and a symphony orchestra so brilliant, their music blows you out of the room.

I’m sure most solid Mystery Hunt teams feel like that to some degree, but I can only talk about my own. Palindrome is an ever-evolving collective of teachers, engineers, programmers, scientists, writers, and who-knows-what-else. We get people who join the team for a single year, just for the experience of it, and we have folks (like me) who have been on the team for decades. As you might expect of people drawn to a gigantic puzzle-solving competition, many of them are smart, and some of them are brilliant. We set up shop online and in a couple of MIT classrooms, and together we assemble a human machine that, it sometimes seems, can solve just about anything. I love being a gear in that machine.

You might think that if you cram dozens of people into a small classroom in the dead of winter and give them puzzles in languages they don’t speak, they might, somewhere around 3 or 4 in the morning, get a little cranky. This doesn’t seem to happen on Palindrome. I’m not even sure why. It’s not like we have a screening process. We’re an open team. Anybody can join us. (Unless we get too big. Then, alas, we have to shut the door.) But somehow each year we wind up with a group that strikes just the right balance of competitive and carefree. We work hard, and God knows we have periods of burning frustration, but it never stops being fun.

And so if you gave me advance warning that in 2020, Palindrome will once again screw up a massive lead and drop down to second place, it wouldn’t stop me for a moment from packing my bags next January.

On the other hand: But seriously, what the hell happened to us? A ten-hour period with no correct solutions? I knew we were stuck on things, of course, but I didn’t realize how long we spent spinning our wheels. Time gets kinda slippery at the Mystery Hunt.

Looking at the puzzles we had open during that time, our weaknesses become clear. They are very human weaknesses. To wit:

Information Overload. Several puzzles required a key insight before you could really start rolling on them. Standardized Mess is a good example. We had that baby open and unsolved for sixteen hours, and there is simply no excuse for it. It’s a fake multiple-choice exam, followed by the seven Scantron forms of various test-takers. Their grades appear on the forms, but for several students, their real grades don’t match the percentage shown. Why? And what sort of hint is tucked into the (as we call it) “flavortext” — that bit about teachers needing to grade these exams quickly. What does that mean?

We filled many different worksheets in a Google Spreadsheet with gobs of information. The true answers; each student’s false answer; if you assign a 0 to each wrong answer and 1 to each right answer, what that would look like in binary, or in hex, or in ASCII.

There was a note on each Scantron form, and the first letters of these notes spelled the word COMBINE. So let’s combine the forms! Let’s combine the grades! Let’s combine the answers! Let’s combine things no reasonable person would expect us to combine!

After sixteen hours, our spreadsheet for this puzzle was an imposing wall of data. Because entering data feels useful: You’re doing something, not just staring, and besides, if you do the right thing — if you cross-reference two pieces of information in just the right way — you never know, the answer might leap out at you!

And yet what was needed here was a fairly simple insight: Why did the puzzlemaker use these questions to generate the right and wrong answers we used to fill our spreadsheets? The light bulb, at long last, flickered to life. Go take a look at the 21 questions and see if you can spot the common element. Go on, I’ll wait. Believe it or not, it’s not really all that hard.

Did you try? Okay. It turns out that every question — every single question on the test — makes a reference to the phrase “upside-down,” or to something famously known for being upside-down. (Houdini, bats, Tobey Maguire in his first Spider-Man movie.) And now it all becomes clear: The teachers graded some of these tests a little too quickly, feeding them into the machine the wrong way. They’re upside-down. If you orient them correctly, and then lay the seven forms on top of one another, the darkened bubbles form the letters in the word FLUNKED, and that’s the answer to this puzzle. We aimed a fire hose of information at our faces, and that kept us from seeing it.

Miscommunication. Palindrome is a large team. In 2017, we peaked at a rather insane 150 people. This year, we had about 100 — not quite as staggering, but still pretty sizable.

In a group that large, it’s pretty easy to miss it when somebody says the exact right thing.

One of the metapuzzles I alluded to earlier combined answers from the Indian holiday of Holi and the Boston holiday of Patriot’s Day. The instructions for the metapuzzle were obscure: We were told we had to start on “the RED route,” without being told what that meant. Okay, then, what are some possibilities? The Red Line of Boston’s T made a lot of sense, but that went nowhere when you tried to apply the puzzle’s other instructions. So maybe another subway system, somewhere else? Tokyo? New York? Maybe a board game like Ticket To Ride?

We discussed this on and off for hours. Along the way, several people said the right answer — Olympic rings — without being heard. It’s not like they knew their suggestion to be correct and trumpeted it with euphoria. No, it was simply a suggestion: Something to consider. We didn’t, until we did, and then got to hear the agony of several teammates smacking their foreheads and saying “I suggested that hours ago!”

Institutional Memory, or Lack Thereof. An excellent point one of my teammates made in our post-mortem is that a small group of solvers could easily waste their time going down the same wrongheaded avenue on a stuck puzzle as a previous group of solvers, because nowhere was the basic idea behind their approach recorded, and the result of that approach revealed. (That data was probably somewhere on the puzzle’s Google spreadsheet, but without a more coherent organizational system, good luck finding it — see Information Overload, above.) One of the key items on my checklist for next year some kind of brainstorming space for each puzzle, so that solvers can see what’s already been tried.

So, yeah. I’d say we learned some valuable lessons this year — the hard way, which is how most valuable lessons are learned. I shake my head in disbelief every time I look at that chart. But the Palindrome Plateau doesn’t shave more than an atom or two off of the sheer enjoyment of Mystery Hunt weekend. Furthermore, our descent from the lead means that Left Out, a stellar team featuring puzzlemakers I admire very much, will be serving up next year’s Hunt. I can’t wait to see what they have for us.

National Spaghetti Day!

National Spaghetti Day!

January 4th is National Spaghetti Day (for some reason), and on this puzzle-intensive blog, we’re naturally going to celebrate it with a game of Spaghetti.

I’m going to give you five words. These words are not — NOT — a puzzle. I chose them at random from a paperback dictionary. Your mission is to find the answer to this set of words, despite the fact that there is no answer and the entire exercise is ridiculous.

If you are a newcomer reading this, you might think this is impossible. How the heck do you solve a puzzle that isn’t really a puzzle? All I can say is, come back often, read the comments, and be amazed. Not every answer is going to make a lot of sense — but somebody is going to find an answer that will make you wonder if the words were really chosen at random in the first place. It happens every time.

Whether or not you submit an answer yourself, I invite you to Like your favorite comments to this thread. The submission with the most Likes will be the winner.

Here are your five words:

SWEEPSTAKES
JOBBER
NEUROTIC
INFANT
VASE

When crafting your answer, you have the option of adding a sixth word to this list–any word you like. Or you can stick with these five.

Good luck!
