# Solo Solving and Single-Player Board Game Fun!

Have you ever been in the mood to play a board game or do some non-paper-and-pencil puzzling, but you don’t have anyone around to play with?

Well, there’s no reason to fret, fellow puzzlers, as there are plenty of options out there for solo gamers and puzzlers.

Today, we’d like to suggest a few options for a terrific single-player solving experience!

The Abandons

I’ll start us off with one of our most recently reviewed games. The Abandons is a one-player maze game where you’re exploring a labyrinth that’s different every time you play. You’re at the mercy of the draw pile for the most part, but the more you play, the better you get at managing your meager resources and exploring the seemingly endless corridors. Can you find your way out?

[If you’re looking for a similar gaming experience, you can also try One Deck Dungeon or Brad Hough’s The Maze.]

Puzzometry

For a more traditional solving experience, Puzzometry presents classic puzzle-solving with a modern twist. This next-level jigsaw-style solving will push your Tetris skills as you twist, turn, and maneuver the pieces into seemingly endless combinations, trying to find the one solution that completes the grid.

There are several different Puzzometry puzzles — the standard one, an easier junior one, and a squares-based one — but each offers its own challenges.

Knot Dice

Can you twist, turn, and spin these dice to complete beautiful, elaborate patterns inspired by Celtic knots? That’s the name of the game with Knot Dice, a dice game as challenging as it is gorgeous.

This is one of those games I find tremendously relaxing as I trace the various patterns and try to form different designs.

Chroma Cube

Deduction puzzles have never been so colorful! Each challenge card offers a different layout of set cubes, along with clues to unravel in order to place all twelve cubes. The clues grow trickier with every card, ensuring that you’ll constantly find new challenges as you solve.

Thinking Putty Puzzle

Our friends at ThinkFun are masters at putting together single-player puzzle-game experiences, and Thinking Putty Puzzle is just one example. It sounds simple at first: connect two colored dots with a length of stretchable putty. But when you have multiple colors on the board and you can’t overlap your paths, suddenly it’s a much more challenging deductive endeavor.

Lightbox

A puzzle box unlike anything you’ve ever seen, Lightbox creates different patterns of shadow and light as you shift and arrange the various plastic plates that make up the box. As you twist and reset them, different electrical connections are made, and different plates light up.

This is another puzzle game that I find quite soothing, even if I can be frustrated by the seemingly endless combinations available.

Pandemic

Although co-op games are designed to bring together several players as they work to defeat the game itself, many co-op games also offer satisfying single-player campaigns. Pandemic allows you the chance to singlehandedly save the world from four deadly outbreaks, if you’re quick and clever enough!

[Forbidden Island, Castle Panic!, and other co-op games are also worth your time if you enjoy this kind of gameplay.]

# A Coin Puzzle: My Two Cents (Plus 97 More)

Our friends at Penny Dell Puzzles recently shared the following brain teaser on their social media:

Naturally, we accepted the challenge.

Now, before we get started with this one, we have to add one detail: which coins we’re allowed to use. It’s safe to assume that pennies, nickels, dimes, and quarters are available, but the question doesn’t say anything about half-dollar coins.

So we’re going to figure out the correct answer without half-dollar coins available, and then with half-dollar coins available.

Let’s begin.

The easiest way to get started is to figure out the smallest number of coins we need to make 99 cents, since that’s the highest number we need to be able to form. Once we have that info, we can work backwards and make sure all the other numbers are covered.

For 99 cents, you need 3 quarters, 2 dimes, and 4 pennies. That’s 25 + 25 + 25 + 10 + 10 + 1 + 1 + 1 + 1 = 99.

Right away, we know we’re close with these 9 coins.

You don’t need more than 3 quarters, for instance, because your possible totals are all below \$1.

Now, let’s make sure we can form the numbers 1 through 24 with our chosen coins. (If we can, we’re done, because once we’ve covered 1 through 24, we can simply add one quarter or two quarters to cover 25 through 99.)

Our four pennies cover us for 1 through 4. But wait, there’s 5. And we can’t make 5 cents change with 4 pennies or 2 dimes. In fact, we can’t make 5, 6, 7, 8, or 9 cents change without a nickel.

So let’s add a nickel to our current coin count. That makes 3 quarters, 2 dimes, 1 nickel, and 4 pennies. (Why just 1 nickel? Well, we don’t need two, because that’s covered by a single dime.)

Our four pennies cover 1 through 4. Our nickel and four pennies cover 5 through 9. Our dime, nickel, and four pennies cover 1 through 19. And our two dimes, one nickel, and four pennies cover 1 through 29. (But, again, we only need them to cover 1 through 24, because at that point, our quarters become useful.)

That’s all 99 possibilities — 1 through 99 — covered by just ten coins.

Well, we can apply the same thinking to a coin count with a half-dollar. For 99 cents, you need 1 half-dollar, 1 quarter, 2 dimes, and 4 pennies. That’s 50 + 25 + 10 + 10 + 1 + 1 + 1 + 1 = 99.

Now, we make sure we can form the numbers 1 through 49 with our chosen coins. (Once we can, we can simply add the half-dollar to cover 50 through 99.)

Once again, we quickly discover we need that single nickel to fill in the gaps.

Our four pennies cover 1 through 4. Our nickel and four pennies cover 5 through 9. Our dime, nickel, and four pennies cover 1 through 19. Our two dimes, one nickel, and four pennies cover 1 through 29. And our one quarter, two dimes, one nickel, and four pennies cover 1 through 54. (But, again, we only need them to cover 1 through 49, because at that point, our half-dollar becomes useful.)

That’s all 99 possibilities — 1 through 99 — covered by just nine coins.

# PuzzleNation Product Review: Zendo Expansion

[Note: I received a free copy of this game in exchange for a fair, unbiased review. Due diligence, full disclosure, and all that. And this concludes the disclaimer.]

Expansion sets have become an integral part of the gaming experience. Whether they offer new wrinkles to an established game, allow you to add additional players, or create new ways to use the same game pieces, they revitalize games that might’ve become less fun or interesting after lots of play.

It’s difficult to strike a balance with expansion sets, since they must respect the game that came before and add to it in a meaningful way, but without introducing any game-breaking mechanics or otherwise compromising what made the original game fun in the first place.

The designers at Looney Labs are absolute pros when it comes to balancing their expansion packs. Each one enhances the gameplay without sacrificing any of the original game’s clarity or cohesiveness.

In the past, we’ve looked at Looney Labs expansions like Fluxx Dice (which add further mayhem to an already chaotic game of Fluxx), the Just Coffee and Better with Bacon expansions for Just Desserts (which add new dishes and characters to deepen gameplay options), and the Bridge Expansion for Star Trek Fluxx and Star Trek: The Next Generation Fluxx (which allow you to combine both games into one).

Today, we’re looking at an expansion pack for one of the company’s most immersive and challenging puzzle games: Zendo.

In Zendo, the players pull pieces from a communal pile in order to build different structures, using pyramids, wedges, and blocks. One player, the moderator, chooses a secret rule for the players to uncover, and builds two structures. One of these structures follows the secret rule, and one does not, and both are marked as such.

Secret rules can be as simple as “must contain all three shapes” or “must contain exactly four pieces.” They can be as complex as “must contain more blue pieces than blocks” or “must contain at least one yellow piece pointing at a blue piece.” Some rules involve how pieces touch, or how they’re stacked, while others demand no touching or stacking whatsoever. The field is wide open at the start of the game.

Players then try to deduce the secret rule by building structures themselves, arranging pieces from the communal pile into various patterns and asking the moderator for more information.

So, how does the Zendo Expansion affect the original?

[The gray areas of the card are variable options to choose from, meaning each card offers several different possible rules depending on the moderator’s choices.]

The Zendo Expansion is a ten-card deck of new secret rule cards that allow the moderator to create more complex and challenging structures for the other players to unravel.

But these ten cards offer much more than just the rules themselves. They encourage both the moderator and the players to be more creative, considering not just the shapes and how they interact, but the overall look of the structure.

One of the cards requires players to shape the structure’s shadow into a given shape. Moving beyond the pieces themselves and incorporating the light and shadow of the play area is a clever and unexpected way to use the Zendo pieces.

It immediately sends your brain in new directions, both as a player trying to deduce other secret rules in later game sessions and as a moderator looking for new ways to prove or disprove players’ theories with your own builds.

Not only does the Expansion deck add all sorts of new twists on the original game, but it makes you want to be more ambitious and clever in your guesses and structures the more you play.

With new rule cards ranging from easy to difficult, players of all skill levels will benefit from adding this set of cards to their puzzle game arsenal.

Zendo and the Zendo Expansion are available from Looney Labs, and both are featured in this year’s Holiday Puzzly Gift Guide!
