Puzzle fans are used to searching for multiple avenues of entry when it comes to solving.

Crosswords have the across and down clues. Some people go straight for the pop culture clues, while others seek out fill-in-the-blank clues. Diagramless crosswords add an additional challenge by removing the black squares and set numbers that guide you.

Fill-Ins and Word Seeks have all sorts of entries you can start hunting through the grid for. Logic problems have several clues you can use to whittle down possibilities and utilize the information you have.

Heck, Rubik’s solvers are positively awash in potential paths to success.

Fans of more complicated jigsaw puzzles are also familiar with this concept. The standard approach is to find the edges and work your way in, but I know plenty of solvers who either sort by color or build from the middle around recognizable figures in the image.

Of course, jigsaw puzzle companies know this and they abandon the traditional rules of jigsaw puzzles, creating some diabolical ways to force you to change your tactics and find new ways in. There are jigsaw puzzles with no edge pieces (meaning no flat edges), so-called “infinite” puzzles like the one pictured above, and brain-teaser jigsaws where the pieces can be assembled in many different ways, but there’s only one correct solution.

And as it turns out, there are a few historical items that prove this sort of multi-approach thinking isn’t limited to puzzles.

Say hello to a marvelous variation on the dos-à-dos book concept that resides in the National Library of Sweden.

Normally, dos-à-dos books (or back-to-back) books are just what they sound like: two books bound together at the spine. But this religious text is six books in one. Depending on which clasps you have open and shut, you can read this book six different ways.

Each book is a devotional text printed in Germany during the 16th century — including Der Kleine Katechismus by Martin Luther — and it’s a masterwork of craftsmanship, skill, and design. It boggles my mind just looking at it.

And yet, a single book with six ways to read it seems like a drop in the bucket when you compare it to a poem that can be read thousands of different ways.

This is Star Gauge, also known as Xuanji Tu (Picture of the Turning Sphere). It is a palindrome poem by Su Hui, a 4th-century female Chinese poet whose most famous creation still amazes to this day.

Written in the form of a 29 x 29 grid of characters, Xuanji Tu can be read forward or backwards, horizontally or vertically or diagonally, or organized by its color-coded grids.

As you might have guessed, it’s called a palindrome poem because it can be read backwards or forwards, though some scholars have estimated more than 2,800 different rhyming poems can be produced by reading it different ways.

Most of her other works have been lost to history, but this one piece alone leaves an incredible legacy.

Whether it’s a six-fold book, a puzzle with an infinite number of arrangements, or a poem with thousands of different interpretations, it’s amazing what you can create with a puzzly mindset and the insight to approach things from a unique perspective.
