It's Snake! It's Snazzy! It's Snazzle! A simple idea puzzle game by Amidos, Snazzle takes its inspiration from the classic formula of slithering reptiles extending themselves by chomping on fruit, and trying to avoid crashing into itself.

At 18 levels including 4 challenge levels, LogicBox is a little short, but Jahooma promises more to come.

Robot wants dots! Okay, the star of Robot Arm, a simple idea puzzle game by Amidos2006 might be missing his torso, head, and legs, but his desires are no less poignant. Robotic Arm offers a cunning test of spatial logic that should appeal to any fan of mechanical manipulation puzzles.

When one wakes up in a featureless white room, apparently at the whims of a malevolent steam-punk computer, the first instinct is to escape. But... why? What's your argument? Can you justify your actions? Such is the question posed by ir/rational Redux, a puzzle adventure game by Tom Jubert, of Penumbra story-telling fame. Propositional logic has never felt so intense!

Are they conveyor belts? Are they fallen trees? To be completely honest, we can't figure out what those strange laser-emitting bricks in increpare's aptly-named Puzzles are supposed to be. All we know is that they cause trouble if you touch them, but yet that danger might be the key to solving the eight enigmas in this game.

Sqr is a retro-styled gravity-based puzzle game from Denis Shilo and Constantine Zaytsev. It looks all simple and unassuming on the surface, what with its 8-bit pixel art and plain tile layout, but once you get twisted within its arrows and buttons, boxes and automated turrets, you'll stop thinking "sokoban" and start thinking "crazy logic puzzle that's trying to kill me"!

We've all had that problem. You know, the one where the Netbots start to plug up the kitchen sink so the water doesn't drain.

When a work has an excellent premise, it's always interesting to find variations on the theme. Haydn knew it. Beethoven knew it. Now Conceptis gets on board with another in their popular series of browser versions of pen-and-paper puzzles, and this time the focus is on perhaps the most popular remix of that ongoing phenom, Sudoku. Chain Sudoku Light Volume 1, designed with the same care as its fellow works, is a twisty variant that's very, very good.

The name of Hashi, the Japanese logic puzzle, is short for Hashiwokakero, literally "Building Bridges". This is entirely appropriate for the game of lines and connections that it is. It's interesting however, that "Hashi" can also be translated as "chopsticks", which also would be a perfectly applicable title. Of course, the appeal of the game goes far beyond linguistic trivia. That should be clear from the success Conceptis found in its previous browser collection of the puzzle. Classic Hashi Light is back in a second volume, and, with a palpable boost in difficulty, your logical reasoning will be tested like never before.

What do you get when you mix the logic of sudoku with the clue-solving challenge of a crossword? Kakuro Light is Conceptis Puzzles' latest entry in their miniature puzzle series, but don't let the tiny package fool you. These puzzles really add up to a tricky challenge!

Created by Japanese math teacher Tetsuya Miyamoto in 2004, Kashikoku naru Puzzle translates literally as "A Puzzle That Makes You Smart". Hitting that exact right combination of mathematical calculation and logical reasoning, it soon became an international sensation under the name KenKen. As the story goes, "Ken" translates as Cleverness, so KenKen (or, I guess Ken^2) is Cleverness-Squared. That's an apt description for this arithmetic grid-based brainteaser.

First Sudoku, then Picross, then Battleship... and now Link-A-Pix. Is there any pencil-and-paper puzzle Conceptis can't expertly translate to the flash medium? Painting by Pairs might be a little more obscure than the previous puzzles collected, but B&W Link-A-Pix Light Vol. 1 continues the streak of high-quality logical mind-benders and is filled with nonograms you'll not want to miss.

Playing God has a bit of a poor reputation: the kind of reputation that leads to torch and pitchfork wielding villagers smoking you out of a burning windmill. However, Alxemy, the new Doodle God-esque puzzler by Hyptod, reminds us that sometimes combining elements to make new life feels more like toying with a new Lego set, rather than a crime against nature.

Classic Battleships Light is the new addition to the Conceptis series of logic puzzle packs. So then, will you sink or swim? With this new batch of quality puzzles, any experience level can dive right in. Anchors aweigh! (And there's plenty more ship puns where that came from.)

In the beginning, there was nothing. Then, some things were created by an all-benevolent superbeing-type god. A not-so-benevolent deity also has a job to do, though, and once the world exists, his task is to cause a little mayhem. The original Doodle God, both the iPhone version and the browser game, focused on creating the universe by mixing basic elements one after the other. Doodle Devil, on the other hand, is about crafting the darker side of life, blending rudimentary concepts together to create chaos.

Bart Bonte's Me and the Key sent us all on a voyage of self- and key-discovery. But the hunt for the self/key is an eternal quest, is it not? Luckily, the journey has been lengthened by another 25 levels in Me and the Key 2.
