Children's Logic Puzzle Has The Internet Baffled
An obscure cartoon riddle has resurfaced on the Internet, causing a lot of people to scratch their heads. It’s thought the puzzle is from an old children’s magazine, although which exactly that is remains a mystery. However, despite being aimed at kids, it's fiendishly hard. The trick seems to be to pick up on every little clue in the picture and then apply every ounce of your logic and knowledge. And even then, it’s pretty impressive if you manage to actually get any of the answers.

Solve lovely-looking puzzles as a pen-and-paper samurai in Inked
Inked, an upcoming puzzle game from developer Somnium Games, has two protagonists. The obvious one is the Nameless Hero, a rogue samurai on a quest for his love Aiko. The other is Adam, the comic book artist who drew the Nameless Hero. "Together they will embark on a journey that will forever change them both," its Steam page reads. The pen-and-papers visuals aren't just for show, then. It sounds like the story is actively being drawn as you play it, which is pretty neat.

100 Prisoners Escape Puzzle
Recently, I wrote about a classic prisoner escape puzzle which, at first glance, appeared impossible. There’s another classic, impossible sounding, prisoner escape puzzle called the 100 prisoner problem. It was first written about by Danish computer scientist Peter Bro Miltersen. In this puzzle there are 100 prisoners, each given a distinct number 1-100. The jailer has decided to give all the prisoners a chance to escape. He prepares a challenge, and if every single one of the prisoners passes, they are all free to go. If even one of them fails, they all die.

Fidgitz™ - Thinkfun
This three dimensional mechanical puzzle begs to be picked up, and may be impossible to put down! Fidgitz twists and turns in a unique fluid motion that will mesmerize players for hours on end. Your goal is to twist and manipulate the puzzle until one side is all blue and the other side is all white. Invented by Bram Cohen of Bittorrent fame, and Oskar van Deventer. I love this puzzle. it is a delight to play with. You solve it and after one move it's gone and getting back to solved seems out of reach.
