Answers to Our 6th Anniversary Instagram Brain Teasers!

Last week, we celebrated six years of PuzzleNation Blog by announcing a week-long puzzly social media blitz.

Facebook and Twitter saw twice-daily alerts for the puzzle of the day for both Daily POP Crosswords and Penny Dell Crosswords App, cuing solvers to contact us with the answers to particular across and down clues.

Instagram solvers were encouraged to tackle a series of brain teasers, and today, we’ve got all the answers for you! Let’s jump right in.


We started off on Tuesday with this relatively straightforward brain teaser: How can you add eight 4s together so that the total adds up to 500?

We got the most responses to this one, and it’s no surprise, as we have some very crafty followers on Instagram. The trick here is number placement. By grouping 4s, you create larger numbers that make it easier to add to your total.

Solution: 444 + 44 + 4 + 4 + 4 = 500


Wednesday’s puzzle involved placing the numbers 1 through 8 into the grid above. Consecutive numbers cannot appear in an adjacent or diagonal box.

This puzzle was actually created and submitted by a PuzzleNationer named Sanjana, so kudos to you, Sanjana, as you made one heck of a brain teaser!

Here’s the solution. (Using the same numbers in reverse or flipped layout creates four different variations on the same solution.)


Thursday’s brain teaser put your Scrabble and Upwords skills to the test, as we played a round of Quad-Doku! The goal is to play each tile, one at a time, onto the board, forming a new common word (or words) each time. Do this with all 8 tiles in any order. By the end, all four corners will have changed.

This is a nice chain-solving puzzle, and here’s the solution we came up with:

F makes FOUR/FIND, S makes FINS/SEEM, A makes SEAM, B makes FIBS, C makes SCAM, W makes SWAM, L makes FOUL/LOOM, and P makes LOOP/SWAP.


On Friday, we posted a riddle to test your puzzly skills. Once I am 24, twice I am 20, three times I am unclean. What am I?

Solution: The answer is X. It’s the 24th letter of the alphabet, two X’s makes 20 in Roman numerals, and three X’s marks something as inappropriate for some viewers.


Monday brought us our final brain teaser, a matchstick puzzle (or, in this case, a toothpick puzzle). Can you move four toothpicks in order to change the zigzag path into 2 squares? The two squares do not have to be equal in size.

In the image above, we’ve circled the four toothpicks to move.

And here is the completed puzzle, with two squares of unequal size.


How did you do, intrepid solvers? Well, based on the responses we received, pretty darn well! We’ll be reaching out to contest winners later this week!

But in the meantime, we’d like to thank everyone who participated in our PN Blog 6th Anniversary event. You help make this the best puzzle community on the planet, and we are forever grateful.

Lollapuzzoola 11 This Weekend!

This Saturday, August 18, marks the eleventh edition of the Lollapuzzoola crossword puzzle tournament!

For the uninitiated, Lollapuzzoola is an independent crossword tournament run by Brian Cimmet and Patrick Blindauer, featuring puzzles constructed with a more freewheeling style than the traditional American Crossword Puzzle Tournament. As they say, it’s “the best tournament held in New York on a Saturday in August.”

The format is similar to BosWords. Competitors are placed in one of four divisions: Express (solvers with tournament experience), Local (other solvers), Rookies, and Pairs.

With seven tournament puzzles — designed with inimitable style, both fun and befuddling in how often they innovate classic crossword tropes — you’re guaranteed to get your money’s worth as you solve.

And for those who reach the top of mountain, “winners in each division are awarded prizes, which could range from a box of used pencils to a brand new car. So far, no one has ever won a car.

Registration is still open if you want to attend in person!

But if you can’t, the At-Home Division is open for any and all solvers to enjoy. For $15, you’ll receive the tournament puzzles the next day for your enjoyment (or frustration, depending on the difficulty).

It should be a great time, either in person or for solvers at home. Lollapuzzoola is one of the highlights of the puzzle calendar.

Are you planning on attending Lollapuzzoola or solving from home? Let me know! I’d love to hear from you!

Six Years of PuzzleNation Blog (Plus a Contest)!

Yes, we’re celebrating today, fellow puzzlers and PuzzleNationers!

We’re celebrating because it is the sixth anniversary of the very first post here on PuzzleNation Blog! Yes, we’ve been on this puzzly journey together since August of 2012, and in my admittedly biased yet humble opinion, it’s been a brilliant one.

In those six years, we’ve published over a thousand posts! (More than nine hundred of them penned by yours truly.) We’ve delved into puzzle history, cracked diabolical brain teasers, marked milestones like the centenary of the crossword, and even rejoiced at puzzly proposals of marriage!

And to celebrate six years of PuzzleNation Blog, we’ve got a week of activities planned for our marvelous readers and fellow puzzlers!

For starters, we’re loading over a hundred new pins to our Pinterest account for your viewing pleasure!

And we’re launching a promotion across all of our social media platforms to celebrate the anniversary. It’s our PuzzleNation 6th Anniversary Contest!

Starting today, and every day for the next five days, we’ll be posting a different brain teaser on Instagram.

Also starting today, keep your eyes peeled on Facebook and Twitter, because each day for the next five days, we’ll be asking for a single answer from that day’s Daily POP Crosswords App puzzle and that day’s Penny Dell Crosswords App puzzle.

(These will be separate from the usual Crossword Clue Challenge posts, and we’ll mark them with “PuzzleNation 6th Anniversary Contest” to distinguish them.)

Message us on FB or Twitter with the answer, or message us on Instagram with the answer to a brain teaser, and you’ll go into a drawing for a terrific prize! (And yes, since there are different brain teasers each day and different answers for each of the two daily puzzles, you can enter multiple times to increase your odds of winning!)

Enjoy the contest, fellow puzzlers. It’s a small thank you for being a part of the PuzzleNation community.

Lollapuzzoola 11 is near!

Saturday, August 18, marks the eleventh annual Lollapuzzoola!

The marvelous indie offspring of the American Crossword Puzzle Tournament, Lollapuzzoola is a favorite of both solvers and top constructors, all of whom descend upon New York City to enjoy what can only be described as “the best tournament held in New York on a Saturday in August.” (At least, that’s what they say on their website.)

The format is simple. Four divisions — Express (experienced solvers who have contended in or won tournaments before), Local (solvers with some experience), Rookies, and Pairs (allowing you to team up to solve) — pit their puzzly minds against clever clues and crafty constructors.

With seven tournament puzzles — designed with inimitable style, both fun and befuddling in how often they innovate classic crossword tropes — you’re guaranteed to get your money’s worth as you solve!

And for those who reach the top of mountain, “winners in each division are awarded prizes, which could range from a box of used pencils to a brand new car. So far, no one has ever won a car.

But if you can’t make it to NYC that weekend, worry not! There’s an At-Home Division that will allow you to participate as if you were there! You’ll get your puzzles by email the day after the actual tournament for a very reasonable $15 fee! Not only that, but you’ll be able to submit your times (and your number of blank/wrong squares) to be officially ranked in the At-Home Division lineup!

It’s one of the highlights of the puzzle world each year, and I’m definitely looking forward to tackling the puzzles! They’re a diabolical treat each and every year! (For a full rundown of the event, check out this interview with Local Division winner and friend of the blog Patti Varol!)

Are you attending Lollapuzzoola or solving from home? Let us know! We’d love to hear from you!

Winning Monopoly With Math!

I’m always on the hunt for tips to make myself a better puzzler and gamer. Sometimes you stumble across those tips in unexpected places.

For instance, I was reading, of all things, a book about mathematics and Christmas — The Indisputable Existence of Santa Claus: The Mathematics of Christmas — and inside, I found a statistical analysis of the best strategy for winning a game of Monopoly.

Yes, we’ve discussed this topic before, but even that previous deep-dive into the mechanics of the game wasn’t as thorough or as revealing as the work by Dr. Hannah Fry and Dr. Thomas Oleron Evans in this Christmas-fueled tome of facts and figures.

They started with a breakdown of how your first turn could go, based on dice rolls. This is the same breakdown as in our previous post, but with some important differences. For instance, they also considered the chances of going to jail after multiple doubles rolls.

Also, they covered the statistical impact of how landing on card spaces can affect where you land on your first turn. The Community Chest is a curveball, because of the possible sixteen cards, three will send you somewhere on the board: Go, Mediterranean Ave, and Jail.

A simple statistical analysis is complicated even further by the Chance cards — nearly half of the sixteen cards send you elsewhere: Go, Income Tax, St. Charles Place, Pennsylvania Railroad, Illinois Ave., Jail, and Boardwalk.

If you extrapolate forward from this point, you uncover some interesting patterns:

The orange property set benefits from all the ex-cons leaving their cells, and after their next turn the reformed criminals will likely end up somewhere between the reds and yellows… Illinois Avenue, with its own dedicated Chance card directing people to it, gets an extra boost, making it the second most visited square on the board.

The property that is visited least frequently is Park Place, where players spend just 2.1% of their time.

Check out this graph. This shows potential earnings from each complete color set, with the dotted line marking the point where your purchase of the property is canceled out by how much the property has earned in rent thus far. Everything above that is profit.

As you can see, blue and brown properties start close to the dotted line, because they’re affordable to buy and build on. The standouts on this graph are New York Avenue (which earns $30 a roll up through thirty rolls statistically) and Boardwalk, which is an expensive investment, but pays off handsomely down the line, remaining the top earning spot past thirty rolls.

Of course, that’s only single properties, and you can’t build on single properties. Let’s look at a chart for full color set revenue:

Some of our previous findings change radically. Boardwalk’s rating drops significantly, because of Park Place’s relative infrequency of being landed on (as we mentioned above).

So which properties should you nab to give yourself the best chance of winning? Well, that depends on how long the game lasts.

The average game of Monopoly takes approximately thirty turns per player, so the larger the number of players, the longer the game will last.

So, for a two-player game, your best bet is to go after the light blue or orange sets, since they’re better in the short term, and the odds are in your favor if the game stays short.

In a three- or four-player game, the orange and red sets are better, because the game is likely to last a while.

And if five or more people are playing, you’re really playing the long game, so the green set becomes your best chance for success.

What about building on those properties? Well, Fry and Evans considered that as well. If you’re playing against multiple opponents and know you’ll be in for a long game, then you definitely want to buy and place houses. But don’t fear if the first house takes a long time to start paying for itself.

As it turns out, your best strategy is to put three houses on your properties as quickly as possible, because the third house is the fastest to recoup on investment. So once the three houses are in place on each property, you can rest for a bit and regenerate your bank before investing further.

And there you have it. Better gaming through mathematics! The only thing better would be, well, playing practically any other game.

Kidding! (But not really.)
