Duke Nukem Forever. Earthbound and Donkey Kong 64 on Virtual Console. DnD RPGs and LucasArts adventure games on GOG.com. What an age we live in, in which vidya games we were once denied are suddenly no longer denied. And now, Chip's Challenge and its fabled sequel, classic puzzle games long thought permanently unrereleasable and unreleasable respectively due to copyright issues, have finally been released on Steam (and let's not forget its spiritual successor from during the drought, Chuck's Challenge 3D). But why stop there? Fans have created a bunch of free extra levels for the original game, including three epic collaborative level packs, and a free program (first version, newer version) capable of running them. The latter version also has a convenient bundle including all three level packs and an intro pack that serves as a tutorial. [more inside]

Simon Tatham's Portable Puzzle Collection "I wrote this collection because I thought there should be more small desktop toys available: little games you can pop up in a window and play for two or three minutes while you take a break from whatever else you were doing. And I was also annoyed that every time I found a good game on (say) Unix, it wasn't available the next time I was sitting at a Windows machine, or vice versa; so I arranged that everything in my personal puzzle collection will happily run on both those platforms and more." In addition to the desktop implementations available at the website, the collection is also available on Android and iOS.
0h n0 is a game of logical deduction where each dot in a grid can only exist in the same row or column as a certain number of like-colored dots. The game will give you specific pieces of information about how many like-colored dots a single dot can "see", and you must deduce the remaining grid of dots. It's from the same people who brought us the zen-like logic game 0h h1 (previously). [more inside]
He was sitting on his bed, surreptitiously surfing the science and math board on 4chan, the notorious underground forum, when he came across a strange image that had appeared on the site three days earlier. It contained a message written in a thin white font against a black background. "Hello," it read. "We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck." It was signed "3301." [more inside]
A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost? Many people give the first response that comes to mind—10 cents. But if they thought a little harder, they would realize that this cannot be right. Keith E. Stanovich writes in Scientific American about “dysrationalia” and how having a high IQ doesn't guarantee that your brain won't take shortcuts when it can.

Ten years ago today saw the English launch of a quirky Japanese puzzler, a sleeper hit that would go down as one of the most endearing, original, and gleefully weird gaming stories of the 2000s: Katamari Damacy. Its fever-dream plot has the record-scratching, Freddie Mercury-esque King of All Cosmos destroy the stars in a drunken fugue, and you, the diminutive Prince, must restore them with the Katamari -- a magical sticky ball that snowballs through cluttered environments, rolling up paperclips, flowerpots, cows, buses, houses, skyscrapers, and continents into new constellations. It also boasts one of the most infectiously joyous soundtracks of all time -- an eccentric, richly produced, and incredibly catchy blend of funk, salsa, bossa nova, experimental electronica, J-Pop, swing, lounge, bamboo flute, hair metal, buoyant parade music, soaring children's choirs, Macintalk fanfares, and the finest theme song this side of Super Mario Bros. Called a consumerist critique by sculptor-turned-developer Keita Takahashi (who after one sequel moved on to Glitch, the supremely odd Noby Noby Boy, and playground design), the series has inspired much celebration and thought [2, 3] on its way from budget bin to MoMA exhibit. Look inside for essays, artwork, comics, lyrics, more music, hopes, dreams... my, the internet really is full of things. [more inside]

On January 5th 2012, an image was uploaded to various image boards. It contained two messages. One was obvious & easy to read. In white letters on a black background it said:
Hello. We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck. 3301As promised there was another message hidden inside the image. It was the start of a bizarre, as yet unexplained chain of complex hidden messages leading those who could solve them on a journey across the Internet and around the world towards a destination none of them could predict with certainty. Is it a highly evolved ARG? Is it a recruitment campaign for the NSA? Welcome to the mystery of Cicada 3301.

A minute is a long flippin' time. Fill it like you care. One of the most minimalistic games to be released last year, Super Hexagon has been praised by many as being hypnotic, addictive, briiliantly designed, and devilishly challenging. It's a game that, like Tetris, delivers pleasure with each inevitable failure, and is simply about reaching escape velocity from your own feeble reflexes. The game has a reputation for turning one's appreciation and apprehension of its challenges into intense addiction, constant improvement, and fervent devotion. [more inside]

What is Spelunky? Well, it's a game that's "as generous as it is bloodthirsty," with "astonishing creativity and spectacular depth." First appearing as a freeware PC game in 2008, Spelunky (previously) is a hilariously brutal and oddly addicting marriage of roguelike, platformer, and puzzler. A new version was released for Xbox Live Arcade on July 4th, with updated visuals and a warbly soundtrack that recall the days of SNES gaming, as well as a deathmatch mode that's been compared to the mayhem of Bomberman. If you're anything like me, you'll get hopelessly consumed. (Trailer. Original freeware version for PC and Mac.)

My father-in-law Jerry is great at word puzzles. Over the holidays, I showed him SpellTower on my iPad.

So I asked Jerry if he would share his strategy

A giant equation is taking form over the course of a few days, on a 46-ft tall "chalkboard" at the corner of Crosby and Broome in NYC. Sponsored by Dow Chemical, it's a mathematical brain teaser with the significance of each term left for the solver to discern. In the first term, for example, the '755' is the length in feet of each side of the great pyramid. Solutions to pieces of the puzzle can be submitted via twitter to @GiantChalkboard. I'm not clear about the commercial aspect of this, or even what exactly "solutionism" is. But if you're a math/puzzle nerd, you'll likely

"Looking at the world through via Google Earth offers striking images of the diversity of our planet and the impact that humans have had on it. Today's entry is a puzzle. We're challenging you to figure out where in the world each of the images below is taken. (You'll find answers and links at the bottom of the entry.) North is not always up in these pictures, and, apart from a bit of contrast, they are unaltered images provided by Google and its mapping partners. So I invite you to open up Google Earth (or Google Maps), have a look at the images below, and dive in. Good luck!"
