You can use the Connected Cube to track your progress and solve times.
AI learns to solve a Rubik's Cube in 1.2 seconds
Researchers at the University of California, Irvine have created an artificial intelligence system that can solve a Rubik's Cube in an average of 1.2 seconds in about 20 moves. That's two seconds faster than the current human world record of 3.47 seconds, while people who can finish the puzzle quickly usually do so in about 50.
Celebrate the 40th birthday of Rubik's Cube with today's Google Doodle
It must be hard being Ernő Rubik. Back in the 1980s, the architect and toy inventor had the rare good fortune of becoming one of very few self-made millionaires from communist Europe. But in the process he was horribly pigeon-holed. His patented Rubik's Cube sold 350 million units, while his other creations -- Rubik's Snake, Rubik's Magic, and presumably a few blocky buildings somewhere in Hungary -- barely got a mention. Today, you can contribute to the injustice of it all by celebrating the 40th anniversary of the first Cube prototype, courtesy of a playable Google Doodle. Meanwhile, the inventor is currently touring the world with an exhibition that is pointedly titled "Beyond Rubik's Cube." Ernő, you have our sympathies.
CubeStormer II rocks a Samsung Galaxy S II, makes CubeStormer I look downright slothful (video)
CubeStormer I was pretty cool, we guess, but that was way back in 2010. Now we're all about CubeStormer II. Built by Mike Dobson and David Gilday, the puzzle-cracking robot is capable of solving Rubik's Cubes at blazing fast speeds, shaving precious fractions of seconds off of human world records. The 'bot was constructed from four Lego Mindstorms NXT kits, with our old pal the Samsung Galaxy S II serving as the its "brain." CubeStormer will be making a public appearance at ARM TechCon 2011 in California, later this month (and really, the whole thing seems like a bit of an ad for ARM -- albeit a really awesome one). In the meantime, check out some video of it in action after the break.
Scientists develop algorithm to solve Rubik's cubes of any size
A computer solving a Rubik's cube? P'shaw. Doing it in 10.69 seconds? Been there, record set. But to crack one of any size? Color us impressed. Erik Demaine of MIT claims to have done just that -- he and his team developed an algorithm that applies to cubes no matter how ambitious their dimensions. Pretty early on, he realized he needed to take a different angle than he would with a standard 3 x 3 x 3 puzzle, which other scientists have tackled by borrowing computers from Google to consider all 43 quintillion possible moves -- a strategy known simply as "brute force." As you can imagine, that's not exactly a viable solution when you're wrestling with an 11 x 11 x 11 cube. So Demaine and his fellow researchers settled on an approach that's actually a riff on one commonly used by Rubik's enthusiasts, who might attempt to move a square into its desired position while leaving the rest of the cube as unchanged as possible. That's a tedious way to go, of course, so instead the team grouped several cubies that all needed to go in the same direction, a tactic that reduced the number of moves by a factor of log n, with n representing the length of any of the cube's sides. Since moving individual cubies into an ideal spot requires a number of moves equal to n², the final algorithm is n²/log n. If we just lost you non-math majors with that formula, rest assured that the scientists expect folks won't be able to apply it directly, per se, though they do say it could help cube-solvers sharpen their strategy. Other that, all you overachievers out there, you're still on your own with that 20 x 20 x 20.
Robot Ruby solves Rubik's Cube in 10.69 seconds, still can't beat humans (video)
There are a few robots smart enough to solve a Rubik's Cube in seconds flat, but a group of students at Swinburne University of Technology think theirs may be the fastest on Earth. Their bot, named Ruby, recently mastered the puzzle in just 10.69 seconds, including the time spent analyzing the cube. To achieve this feat, the device scanned the toy with a webcam before its software processed the images to crank out a solution. According to the university, Ruby's 10-second mark smashes the current world robot record of 18.2 seconds, unofficially making it the fastest cube-solving machine on the planet. But Ruby still has a long way to go before it catches Feliks Zemdegs -- a 16-year-old Australian who solved a Rubik's Cube in 6.24 seconds and continues to carry the torch for all of humanity. Twist and turn your way past the break for the full PR and a video of Ruby in action, as well as a clip of Zemdegs showing us how the pros do it.
HTC Desire solves dodecahedron Rubik's Cube, will blow your mind (video)
If this image doesn't have you completely dumbfounded, scroll down and watch the video. Sufficiently awestruck? Good. Now, for a little background on exactly how someone got a pile of Legos and a smartphone to solve the devil's puzzle Megaminx. The aptly titled Megaminxer enlists the Mindstorms NXT kit to do the dirty work and an HTC Desire, running a custom Android app, as the brains of the operation. Said app uses the phone's camera to take individual images of each of the puzzle's 12 faces, then processes the information and sends a signal via Bluetooth to the NXT controller, which in turn goes to town. Unfortunately, there's no explaining how they got the Android to dance like that, but, really, why ruin the magic? [Thanks, Stuart]
Rubik's Cube solved in twenty moves, 35 years of CPU time
The term "God's number" refers to the minimum number of moves that it takes to solve a puzzle like the Rubik's Cube. Because, you know, if God truly is omniscient (and not a node in a vast satellite network, à la Philip K. Dick) you can bet your bubby that it would be able to solve such a puzzle in the minimum number of moves -- and it would have nothing better to do all day than solve puzzles. According to a team of engineers and some thirty-five CPU years worth of idle computer time (supplied courtesy of Google) it has been established that of any of the cube's 43,252,003,274,489,856,000 potential positions, a solution can be found in twenty moves or less -- making God's number twenty. And we're guessing that any of those solutions has to be more satisfying than our Uncle John's own Rubik's Cube solution (which he taught us in the early 1980s), removing the stickers and putting them back on in the proper sequence.
Motorola Droid solves Lego-encased Rubik's Cube in 24 mind-melting seconds (video)
Oh sure, you've seen your disgustingly hairy cousin solve a Rubik's Cube in 3 minutes and 13.4 seconds, and we've seen quite a few sophisticated robots do it in far less time. But in the latest episode of "Yes, Droid Really Does," we've got Motorola's darling solving a Lego-encased Cube in just over 24 seconds. Let's recap: a Droid, a Mindstorms NXT monstrosity, a Rubik's Cube and faux techno. Is there any chance you aren't clicking through to watch this video? Update: Whoops -- had the wrong image in there somehow. Fixed now! Update II: Drats -- the video owner removed the clip. We'll keep it embedded should it return. Update III: It's back! Check it after the break.
Lego Cubestormer robot solves Rubik's Cube in sub-12 second whirlwind (video)
Robots born with the sole purpose of solving the Rubik's Cube are nothing new, but we're pretty sure we haven't seen one crack the code in under a dozen seconds before. The Cubestormer, which is built from a myriad Lego Mindstorm kits, recently took hold of the famous block and lined up every color without breaking a sweat. Oh, and did we mention that it took less than 12 seconds? It's worth noting again, either way. Hop on past the break and mash play to have your mind blown, not to mention your own intelligence insulted.
NintendoWare weekly: Bejeweled, Blaster Master, Earthworm Jim 2
As promised, Sunsoft's brought Blaster Master to the Virtual Console -- though we think the impact is somewhat dulled by the quantity of other games available for download this week. There's a total of 11 different games available, so head past the break for the full list.
Kid plays Guitar Hero while solving two Rubik's Cubes
We frequently like to joke that people who show remarkable adeptness at Guitar Hero are actually robots, but as you might imagine, we don't really mean it. However, after viewing a recent video (posted after the jump) showing a young man who not only plays through Ozzy Osborne's "Mr. Crowley" on Expert, but solves two Rubik's cubes while doing so, the only logical explanation we can come to is that his deft hands and keen mind must be composed of wires, servos and cold, unfeeling steel.By the way, if you happen to speak ill of this young automaton's abilities due to his only receiving a score of 77 percent on the song, we're going to punch you in the heart. We may even call you a "stupid jerk," depending on how much of our ire you end up evoking.[Via Kotaku]
Rubik's TouchCube to make debut this weekend... on QVC
It's not every day that QVC gets first dibs on hot new gadgets (though it's occurring far more frequently than we're proud to admit), but we're hearing that the teleshopping channel will be the place to go if you want to be among the first to own a Rubik's TouchCube. Believe it or not, the swipe-controlled retro toy will be available to buy for the first time on the Christmas in July segment this weekend. Look - if you've been wondering what QVC looks like in full, unadulterated HD, but have up until now failed to secure a good excuse to check it out, this is your chance, and yes, you're welcome. The full statement from the company is after the break.
Rubik's TouchCube hands-on and video
We just stopped by TechnoSource's booth at the Toy Fair to check out its just-announced Rubik's TouchCube, a fully touch-sensitive update on the old classic Rubik's Cube. The new model boasts a few features the old one did not (besides the lights and touchscreen), namely undo and hint options if you get stumped. Each of its six sides are touch-sensitive, and the cube's got an internal accelerometer so that it only recognizes the touching going on on the top side of the cube. It also remembers your place even if you turn it off -- great for those of us who will likely spend years trying to solve it just once. The Rubik's TouchCube is going to hit shelves this fall for $149.99. Check the gallery and video demo after the break %Gallery-45090%
Rubik's Cube gets spherical twist as Rubik's 360
Unlike Microsoft's own Xbox 360, the Rubik's 360 is actually round. Imagine that, right? Said device is about to be officially unveiled in Germany this week at a national toy show, and while many question its ability to recreate the wonder and amazement associated with the original Cube, puzzle aficionados the world over are still enthusiastic about giving it a go. The unit features six balls trapped inside of three transparent plastic spheres; in order to solve it, players must figure out how to get the internal balls "from an inner sphere into matching slots on the outer sphere by shaking them through a middle sphere that has only two holes." Sadly, we'll have to wait until August before being perpetually frustrated by yet another Rubik's invention, but needless to say, we're pretty stoked to get irate later this year. [Thanks, Sam]
CubeCheater solves that Rubik's Cube for you
As we know from the iPhone television commercials, if there's something you need to do, there's an app for that. And so apparently, if the thing you want to do is solve a Rubik's Cube, then yes, there is an app for that. CubeCheater will help you quickly solve a Rubik's Cube -- all you do is punch in the colors on your cube right now, and then you get directions, complete with rotating graphics, on what steps to take to solve the cube. It's not built from scratch -- the app uses an algorithm already developed for solving the Cube -- but it does take advantage of a surprising amount of the iPhone's features. You can draw the colors on the virtual cube yourself, or even take a picture of your cube's sides and the app will recognize where the colors are. The latest update adds support for non-standard cubes, so if the colors aren't quite the same on your cube as on the screen, you can change things around. Impressive, even if it is a little limited in practicality. It's in the App Store right now for 99 cents. Obviously, the point of a Rubik's Cube is solving it yourself. And if you really want to cheat, you don't need an iPhone. Just do what I do: take the little stickers off and replace them in the right places. [via Cult of Mac]
ELAC's MicroSUB 2010 BT: the most rumbling Rubik's Cube you ever did see
We've seen some pretty ingenious covers for earth-movers, but ELAC's Rubik's Cube-inspired MicroSUB 2010 BT is really something special. Sure to please both puzzle and bass lovers alike, the dual-driver subbie features built-in Bluetooth (A2DP), 100-watts of power and a pair of speaker outputs for satellites. For those looking for less vivid versions, it is available in black or white, but really, where's the fun in that?[Via Unplggd]
Rubik's World looks neat, is presumably a game of some kind
The first screens of Rubik's World, the puzzle game based on the colorful cube (which is, of course, a decorative item only, and not a solvable puzzle) show a beautiful, stark white environment and items made of Rubik's Cube components -- and no information at all about what the game is or how you would play it. Do you build a Rubik's Tree? Do you arrange parts into the shape of a tree? Do you throw a ball at it and knock it over? We're going to have faith that this is a game and not merely a 3D block building kit.The press release accompanying the game refers to stuff like living "Cubies" you can interact with, music composition, and unspecified puzzles of some kind, as well as the classic Cube gameplay. We hope that whatever this turns out to be is as cool as it looks, because we could spend quite a bit of time staring at what basically amounts to 3D pixel structures.
Rubik's World set to stump Wiis
This blogger is more likely to throw a Rubik's Cube into a raging fire than make a realistic attempt at solving one, but surely some of you superfreaks readers out there enjoy the challenge. It's for people like you that Rubik's World was conceived, as it combines the iconic 1980s toy with modern-day technology.This piece of software by The Game Factory promises "extremely addictive" puzzles that involve constructing 3D objects (therefore, you needn't worry, it won't simply be a virtual Rubik's Cube game). The press release also mentions navigating through mazes and creating your own soundtrack, the latter of which piques our interest.Local multiplayer will support up to four players, but sadly, there will be no online play (aside from picture swapping and leader boards).
