11 Variations on the Rubik's Cube


The classic Rubik's cube is available in different configurations, such as 2x2 pocket cube, the standard 3x3, and the more difficult 4x4 Rubik's revenge, and the 5x5 professor's cube. Yes, there are more difficult ones, too.

1. Grayscale Rubik's Cube


The Grayscale Rubik's cube is the same as the standard 3x3, but without the bright contrasting colors. The sides are different shades, but just barely! The moves are the same, but difficult because of the extra concentration required in distinguishing the colors.

2. Photo Rubik's Cube

You can have a personalized Rubik's cube made from six photographs. Each photo will be sliced into nine squares. This will make it hard for anyone who isn't familiar with the photos to solve it, so if you've never solved one, there's a chance someone else might mess it up for you. And cubes that must have all squares lined up in a certain orientation are more difficult, as they have a thousand times more possible configurations.

3. Rubik's Cube Earth


This is cool. The basic Rubik's cube with a map of the earth printed on it. Even if you're a cube quiz, you have to have some basic idea of geography to solve this. And it's a great conversation starter.

4. Magnetic Dice Cube


When I first saw this, I thought it was awesomely retro to make a Rubik's cube from even older gaming cubes, but that's not all there is to it. This dice cube is held together by magnets instead of the Rubik's mechanism! If you can't solve it, you can easily take it apart.

5. Sudokube


Sudoku is one type of puzzle I deliberately avoided learning to do, for fear it would suck up all my time. But if you know a Sudoku enthusiast, they'd have a ball with the Sudokube.

6. Fentix Cube

Andrew Fentem designed this electronic touch-sensitive cube to emulate a Rubik's Cube. It's as much art as it is a game!

7. Megaminx


The Megaminx is shaped like a desk calendar paperweight, with 12 sides. It has 50 moveable pieces, compared to 20- on a standard Rubik's cube.

8. through 11. Other Variations


Other shape variations include the Pyraminx, the Skewb Diamond, the Dogic, and Alexander's Star. I can only imagine the crazymaking that comes with these.

The Richest Person of All Time From Each State

Looking for inspiration in your quest to become a billionaire? This map from cost information website, spotted by Digg, highlights the richest person in history who hails from each of the 50 states.

More billionaires live in the U.S. than in any other country, but not every state has produced a member of the Three Comma Club (seven states can only lay claim to millionaires). The map spans U.S. history, with numbers adjusted for inflation. One key finding: The group is overwhelmingly male, with only three women represented.

The richest American by far was John D. Rockefeller, repping New York with $257.25 billion to his name. Amazon's Jeff Bezos and Microsoft's Bill Gates clock in at the third and fifth richest, respectively. While today they both make their homes in the exclusive waterfront city of Medina, Washington, this map is all about birthplace. Since Gates, who is worth $90.54 billion, was born in Seattle, he wins top billing in the Evergreen State, while Albuquerque-born Bezos's $116.57 billion fortune puts New Mexico on the map.

The richest woman is South Carolina's Anita Zucker ($3.83 billion), the CEO of InterTech Group, a private, family-owned chemicals manufacturer based in Charleston. Clocking in at number 50 is the late, great socialite Brooke Astor—who, though a legend of the New York City social scene, was a native of New Hampshire—with $150 million.

A hidden image illustration by Gergely Dudás, a.k.a. Dudolf

Gergely Dudás is at it again. The Hungarian illustrator, who is known to his fans as “Dudolf,” has spent the past several years delighting the internet with his hidden image illustrations, going back to the time he hid a single panda bear in a sea of snowmen in 2015. In the years since, he has played optical tricks with a variety of other figures, including sheep and Santa Claus and hearts and snails. For his latest brainteaser, which he posted to both his Facebook page and his blog, Dudolf is asking fans to find a pet ghost named Sheet in a field of white bunny rabbits.

As we’ve learned from his past creations, what makes this hidden image difficult to find is that it looks so similar to the objects surrounding it that our brains just sort of group it in as being “the same.” So you’d better concentrate.

If you’ve scanned the landscape again and again and can’t find Sheet to save your life, go ahead and click here to see where he’s hiding.
