PuzzleNation Product Review: Pocket Brainteasers

[Note: I received a free copy of each brain teaser in exchange for a fair, unbiased review. Due diligence, full disclosure, and all that.]

Whether it’s composed of two simple pieces of twisted metal or a elaborate arrangement of parts, a mechanical brain teaser are great fun. It’s a plaything, a curiosity to be fiddled with, tinkered with, and explored, twisted and turned every which way until you feel like you’ve got a handle on all the different ways you can manipulate it.

And then, suddenly, BAM. Inspiration strikes! The a-ha moment happens, and you unravel its secrets.

ThinkFun, purveyors of deduction and logic puzzle games galore, have returned to the field recently, and in today’s product review, we look at a collection of brain teasers that each offer their own unique a-ha moment, if you’re willing to work at it.

ThinkFun’s Pocket Brainteasers range in difficulty from one to four (one being the easiest/least challenging), and you’ll find your puzzle skills tested in several ways as you tackle each. Although intended for solvers 8 and up, older solvers will still enjoy the puzzly tricks awaiting them in ThinkFun’s latest line of puzzle products.

4j1

4-Piece Jigsaw

It sounds simple, doesn’t it? A four-piece jigsaw puzzle. Better yet, it’s already assembled for you! All you have to do is take it apart.

This level 1 brainteaser is obviously more than meets the eye, as the puzzle pieces shift back and forth but never quite seem to separate the way you’d expect.

4j2

The large plastic pieces are perfect for younger solvers to play around with, solid and resistant to the sometimes harsh manipulations of younger hands.

It’s not much of a challenge for an experienced solver, but it was genuine fun to suss out how the pieces worked together and how to finally separate them.

4j3

4-T Puzzle

This level 2 brainteaser followed the same basic formula as 4-Piece Jigsaw — four pieces to assemble — but in this case, their interactions were constrained by the small tray included with the puzzle.

4j4

As you can see, the solution offered on one side simply won’t work on the other because the tray is smaller, so solvers will have to be extra crafty to place all four T-blocks into the available space.

The T-shaped pieces made for curious solving — since they don’t fit flush with the corners the way traditional tangrams or Tetrominoes would — but patience and cleverness will be rewarded. It’s amazing how a relatively simple set-up — shapes and a tray — can result in a satisfying puzzly experience.

4j5

The Fifth Chair

This time around, there’s no tray or framework to negotiate. Instead, you’ve got four L-pieces (or “chairs”) and your goal is to make a larger L-shaped chair by combining the four you already have.

Like a three-dimensional version of tangrams, The Fifth Chair is an enjoyable solve, requiring you to maneuver the chairs in all sorts of combinations, seeing different relationships between them all as you try to figure out how to bring the fifth chair to life.

Despite being the level 3 puzzle in the set, I actually found this to be the most challenging of the quartet, as I was briefly overwhelmed by the sheer number of options available to me.

Of course, as soon as I figured out the solution, it felt obvious, and I breathed a sigh of puzzly relief as I conquered the third of four brainteasers for the evening.

4j6

Rec-Tangle

Designed to resemble the service bars of a cellphone or an internet connection, the “bars” are cut diagonally into halves, leaving the solver with 8 pieces to arrange.

This level 4 puzzle solves quite similarly to 4-T Puzzle. You have an array of pieces to place into a smaller space on the backside of the puzzle tray.

4j7

The unusual pieces — long and thin, with an angled edge on one side and a flat end on the other — offered all sorts of possibilities when it comes to placement in the tray, so I found myself discarding quite a few theories and ideas before alighting on the correct solution.

Nonetheless, I would still consider this puzzle easier than The Fifth Chair, though still harder than 4-T Puzzle or 4-Piece Jigsaw.

Tackling this tetrad of brainteasers was a treat, especially as it felt like I was exercising plenty of puzzly skills that aren’t used nearly as often as pen-and-paper puzzles usually demand.

The combination of spacial awareness, physical manipulation of puzzle pieces, and the strategy involved in cracking each made for a feast of puzzly experiences. Any one of the four would be fun, so getting to try all four was a delight.

Whether intended as stocking stuffers or affordable little puzzly surprises for the solver in your life, I suspect these pocket-sized puzzles will have the younger solvers you know puzzling away for a while to come.

Pocket Brainteasers are available from ThinkFun and select online retailers, only $6.99 each for 4-Piece Jigsaw, 4-T Puzzle, The Fifth Chair, and Rec-Tangle!

PuzzleNation Product Review: Chroma Cube

Posted on by

[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.]

As longtime readers know, puzzle games centering around logic and deduction can come in many different forms, from cats milling around a living room to abstract shapes interacting in curious ways. They often have many moving parts and solving mechanics to keep in mind.

But other logic puzzles strip away flashy trappings and overly elaborate designs and take a minimalistic approach to puzzling. The subject of today’s product review, Chroma Cube, falls neatly into the latter category.

Chroma Cube boils a deduction puzzle down to its essentials, employing pleasing design that seems basic, but allows for great depth and challenge nonetheless. All you need to tackle Chroma Cube is a game board, twelve colored cubes, and your challenge cards.

The object of the puzzle is simple: complete each challenge card by placing all 12 cubes in the correct positions on the board.

Most of the challenge cards place some of the colored cubes for you to get your started. Once you’ve set up your board to match the starting pattern on the card, it’s up to you to use the clues provided to figure out how to place the remaining cubes.

The challenge cards ease the solver into the puzzle at first, relying mostly on clues about positioning on the board, referring to rows, columns, and neighboring cubes.

As you might expect, with each new challenge card, the puzzles increase in difficulty, and the clues grow more complex and inventive. Some refer to colors only by the first letters — leaving you to ponder whether it applies to Brown or Black, for instance) — while others offer contextual clues, like a rule that the cubes in each row should be in alphabetical order from the left to right.

A few even rely on knowledge outside the puzzle game itself, like knowing the colors in the Irish flag. These clues are rarer, but add a nice bit of crossword-style flavor to an otherwise Sudoku-like solving experience.

The team at Project Genius did an excellent job of keeping the clues fresh and interesting, constantly introducing new rules and wrinkles to the puzzles. By the time you’re encountering puzzles with no set cubes, or ones that require you to swap set cubes with newly placed cubes — a very clever twist on the idea of “set” pieces — you realize that no matter how many tricks you’ve figured out, the challenge cards have new ones waiting for you.

(Naturally, these are only some of the clue mechanics you’ll encounter. I don’t want to spoil some of the really inventive and challenging ones.)

Chroma Cube’s later challenge cards offer plenty of difficulty and cluing craftiness to keep established puzzlers coming back for more, but without alienating new solvers that have developed and honed their deductive talents by playing through the game’s earlier scenarios.

I was thoroughly impressed by how much the creative team at Project Genius got out of 12 colored cubes and a wooden board to place them on.

Not only that, but the game is beautiful, eye-catching in its presentation. The wooden pieces have a weight to them, and solving is a delightfully tactile experience. (The challenge cards can be tucked away in a slot within the board, making it a breeze to move around the house.

Heck, you could easily leave it on your coffee table as a puzzly conversation piece and it wouldn’t look out of place.

Chroma Cube is a wonderfully visual take on classic deduction-style solving, one that will keep you on your toes from the first challenge card to the last.

Chroma Cube, distributed by Project Genius, is available at Barnes & Noble and other participating retailers.

Other puzzles you might not know! (Volume 3)

Posted on by

In previous editions of this series, we’ve presented some new puzzles for crossword devotees and Fill-In fans to try out. Today, let’s turn our attention to Sudoku enthusiasts.

Now, before we talk about other types of puzzles, there are numerous Sudoku variants to choose from, if you’d like just a little twist on the familiar Sudoku formula. In fact, I did an entire blog post about them, as well as posts about new variants like Will Sudoku and Pentdoku Puzzles!

There are a few lesser-known number-placement puzzles out there that might scratch your puzzly itch if you’re a Sudoku fan: Futoshiki and Beehive Hidato.

[Futoshiki image courtesy of PuzzleMagazine.com.]

Futoshiki will seem fairly familiar, since the row and column rules of Sudoku are in effect. But you have an additional placement rule to consider: the less than/greater than signs in the grid, which indicate where to place lower or higher numbers in the grid. (Futoshiki translates to “not equal” in Japanese.)

[Hidato image courtesy of TheGuardian.com.]

Beehive Hidato eschews the traditional Sudoku row/column system of the deduction in favor of chain-placement of numbers in its hexagonal grid. Your goal is to fill every cell in the grid by filling in the missing numbers between 1 and the highest number. So, instead of placing the same numbers in every row and column, you’re placing a different number in each cell, forming a single chain from 1 to the last number.

The cell containing the number 1 must neighbor the cell containing the number 2, and the cell containing the number 2 must neighbor the cell containing the number 3, and so on, all the way around the grid.

If you’re looking to go a little farther afield and leave numbers behind, I’ve got you covered.

After all, some people tend to think of Sudoku as a math puzzle, but it’s really not; it’s more of a deduction and placement puzzle. You could check out not only Fill-Ins, but also all the puzzles I’ve previously recommended for Fill-In fans. That’s a great place to start.

You could also try your hand at Brick by Brick.

[Click here or on the grid for a larger version.]

Brick by Brick puzzles are a terrific bridge between placement puzzles and crosswords, using aspects of both. You’re given the complete first row of a crossword, and all of your clues, both across and down.

But, instead of the black squares you’d normally rely on to help guide you through answering those clues and placing your words, you’ve got 3×2 bricks filled with letters and black squares, a scrambled jigsaw puzzle to reassemble.

Here you can use your deductive Sudoku skills to place black squares and entire bricks into the grid as you apply crossword-solving skills toward answering the across and down clues, working back and forth between the two to complete your grid, assembling chunks of answer words as bricks fit neatly together.

And if you prefer quote puzzles to crossword puzzles, there’s always Quotefalls.

[Click here or on the grid for a full page of Quotefalls.]

Quotefalls gives you all of the letters in a given quote, plus the black squares that separate each word from the next. But it’s up to you to figure out where in each column to place the letters above so that the quotation reads out correctly.

Sometimes that’s easy, like in the fourth column of puzzle 2 above. Since there’s three black squares and only one open square, you know exactly where that E will go. Seedling letters like that can go a long way toward helping you fill each word, and eventually, the entire quote.

It’s a different form of deduction, but one not too terribly far from the number-placement solving of Sudoku.

Any one of these puzzles could add some welcome variety to your puzzle solving, while still honoring the style and play inherent in your favorite puzzle. Give them a shot, and let us know how you like them.

Next time, we’ll be tackling recommendations for Cryptogram fans, but if you’ve got puzzle recs for your fellow puzzlers in the meantime, please let us know in the comments!
