After a near 5 year hiatus the diverse and devious puzzles of M have returned. As of yet, we don't know how frequently we'll be given our next challenge from the shadowy M. Previously puzzles were posted weekly, while further puzzles lurked within the seals. All the puzzles, prior to the interregnum are still up and waiting for you to have a crack at them.
"Below are sixty wee puzzles. I’ve tried to provide a heads-up where there’s a whisper of off rhyme or a slight shift of emphasis. The one consistent exception I’ve allowed to perfect rhyme is that at the center and fulcrum point of the puzzle, there may be a possessive “s.” The answer to “White whale’s home haircutting gizmo,” then, would be “Moby[’s] Flowbee.”" [more inside]
Here's a great new game: Find the ThingX among a sea of ThingYs... It began with a panda in a picture full of snowmen. Then a cat in a flock of owls. (YOLO: You Obviously Like Owls) Another panda, hidden among elephants (harder than you'd expect). More pandas among Star Wars Stormtroopers and Black Metal Rockers. Also, for Star Wars Fans and all movie lovers, one Oscar among dozens of C3POs. A literal Easter Egg among bunnies. Some puzzles like these are easier (and less creative) than others. And the latest and greatest: find a certain celebrity/candidate's hair in a pile of tribbles.

"In keeping with James Joyce’s own love of lists, here’s a terribly subjective list of ten books published in this century that are in different ways as inventive as Ulysses was in 1922. These novels aren’t necessarily inspired by Ulysses, except insofar as it has affected every subsequent novel, but like Joyce’s masterpiece they challenge us in ways we never knew to expect. If nothing else, Bloomsday should remind us to pick up some books not despite their difficulty but because of it." (Electric Literature) [more inside]
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]

"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!"
