Puzzle games are good brain food, and this recent addition to the iPhone library is no exception. The first mobile app from EatonLabs Ltd., PixBlock, reincarnates a well-known kind of logic puzzle that puts your pixel painting logic to the test. It's picross, folks, and it's a stylish and simple implementation that makes playing as easy as scribbling on a piece of paper.

It's a well-known fact that one can never get enough of Picma Squared. The browser release introduced us a stylish version of Fill-a-Pix (or, as some like to call it, picross meets minesweeper), and with the mobile release of the game, your digital logic puzzles are now portable!

Have you ever wondered how to combine a puzzle you love, like sudoku, with something you've always feared, like gym class? Maybe not gym class, but how about math class? Conceptis Puzzles' CalcuDoku Light is the latest edition in their Conceptis Light series, and this puzzle pack features plenty of mathematical mayhem to keep you occupied.

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. Or the one where the Netbots keep your bowling ball from coming back down the ball return at the local bowling alley. Managing the Netbots can be quite a tricky task, as a group of scientists find out in Maik Haider's Netbots, a puzzle where you have to learn to divide to conquer.

Need a dash of rainbow splashed across your logic puzzles? Conceptis delivers a cacophony of colorful curiosities with Color Pic-a-Pix Light, the latest addition in their Conceptis Light series.

Regardless of your experience level, these path-forming challenges are a great way to spend a good stretch of time.

If you've spent any time around the indie gaming scene, you're familiar with the name increpare, also known as Stephen Lavelle.

The game looks fantastic and plays like several of your favorite logic puzzle games rolled into one superb, pseudo-3D package.

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.

A Day in the Woods is a sliding puzzle adventure from Retro Epic that stars none other than Little Red Riding Hood.

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!

Flush with the success of its recent movie adaptation, Minesweeper's star had never been higher in the eyes of the world. However, taking to heart the criticism that it's gameplay has been a little "flat" since the Windows 3.1 years, it began to seek a new dimension in its to hook the younger audience. One conference with foreign auteur Vjekoslav Krajacic later, and the result is Minesweeper 3D: Universe. No entry surcharge neccesary.

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. At JayIsGames, we're always on the lookout for good online versions of pen-and-paper games, and Nextoy has provided with 6 daily, devious, and easily-printable KenKen. Why? Because they Ken Ken Ken!

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.)

It's another great entry in the logic puzzle universe that's primed to be your main resource for picross!

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.
