Tired of combining elements on a tiny mobile screen? Ready for something bigger, more feature-rich, and Retina-optimized? Doodle God has finally made the leap to iPad with Doodle God HD. The release coincides with a big 2.0 upgrade for the iPhone version, adding a brand new interface, new artifacts, new reactions, new achievements, improved mini-games, and more. Two new modes of play have also been added: Puzzle and Quest. Puzzle challenges you to create buildings, trains and all sorts of massive objects by combining basic elements, while Quest gives you three different story scenarios you must find a way to solve. Lots of great stuff for the Doodle God fans out there!

Do you like numbers and loops? Of course you do! You're only human. Conceptis, the team who brought pencil puzzles like Link-A-Pix and Nurikabe to the web, are continuing their trend of porting their browser puzzles to the iOS platform, trading in the scratch of a pencil or the click of a mouse for the tap of a finger. Their latest App Store addition is Conceptis Slitherlink, a mobile iteration of their loopy logic puzzle Slitherlink Light.

NonoCube from Graycode Software takes the familiar picross puzzle and bumps it into the world of 3D. Now, instead of filling in squares on a flat grid, you carve out a shape by twisting and turning a cube shape floating freely in space. The same rules of logic still apply, you just have another dimension to worry about solving!

Yummies is a logic-based puzzle game from YUMMY Factory, the team behind the mobile brain teasers IQ Mission and IQ Mission: Epilogue. Your goal is to guide squishy-looking aliens to their respective capsules, nudging them along paths while you deal with all sorts of barriers and blockades. It's an extremely cerebral experience that's softened by a phenomenal visual presentation, right down to the grinning little aliens you'll be helping out.

Adrift is a stylish logic puzzle game from Tack Mobile. It follows the gameplay outline of classic browser games such as Hyper Frame and 3D Logic II, eliminating the rotating cube in favor of a fixed isometric viewpoint, simple touch controls, and a sweet-as-candy visual presentation. Don't think that just because you only have three sides of a cube to worry about that things are going to be any easier to solve, however!

Minesweeper is the kind of game everyone's played at least once in their life. Or 57 times simply because, hey, it's there. When you combine zombies and the very familiar logic puzzle you get Zombie Minesweeper, a game from Frogtoss Games that is exactly what it sounds like: minesweeper with zombies chasing after you. Your job is to carefully move across the minefield, planting flags to mark dangerous tiles while you aim for the detonator at the end. Reach it and it won't be your brains splattered across the place.

Eighty-Eight is a puzzle game from Premiere Liaison that smashes together numbers and logic. The simple set-up places you on an 8x8 grid of squares with a few blocks resting comfortably at the bottom. New blocks appear, ready to be dropped, and with a little bit of forethought (ok, boatloads of forethought) you can create some elegant chain reactions and keep the screen as empty as possible. Or, you know, panic and start crying because THE NUMBERS ARE EVERYWHERE.

Art restoration is a tricky business. Make one false move, and you turn a beautiful fresco into a bowl of mashed potatoes. You can try your hand and bringing pictures back to life with Puzzle Restorer by Gavina Games. Mix and smear the paint around the grid, and try to match the target image. Your paints and brushstrokes are limited, so make every move count!

Puzzle game plus farming plus mega-mustachioed man equals Sprinkfield, a logic-based game from Webstar Works that's as simple as watering the lawn. Well, not that simple, but it starts out with that basic direction and adds a little extra complexity from there. It's also a mighty handsome looking game, which is always a nice plus!

The clock is ticking, the fuse is burning, and the stakes are high... You're the only bomb technician in town who can defuse the logic puzzles in ShellBlast Forever, a mobile version of the Minesweeper-esque downloadable game by Vertigo Gaming. As you slide the SDUs around the grid, can you tell which tiles are deadly triggers from the numerical clues provided?

More mobile Conceptis puzzles, hooray! The team that practically invented the online presence of pen and paper logic puzzles has released an iOS conversion of one of its browser-based offerings. This time it's Conceptis Nurikabe, a touch screen friendly incarnation of Nurikabe Light. It has a very similar interface to the browser games, offering an easy way to work on hundreds of puzzles on the go without having to sharpen a single pencil.

Color Alchemy is a sparsely-styled mobile puzzle game from Element Modulus that challenges your ability to mix, split and alter beams of color. By dragging paths and adding special tiles to manipulate colors, you'll create some complex scenes that look like a truck carrying rainbows crashed into a Skittles factory. Just, you know, not as tragic. And with loads of levels and some painfully mind-bending puzzles, you've definitely got your work cut out for you.

And what made you think your super secret spy assignment was over? Put on your spy hat (a baseball cap turned backwards, your home team's logo marked out, of course), polish off that decoder ring, and sit down with your mobile device to enjoy IQ Mission Epilogue, an expansion to the original IQ Mission puzzle and brain teaser game that adds three new cities, each featuring the same extraordinarily high level of artwork and music that makes the experience just irresistible.

The best mobile games are the ones that make us feel smart, are easy to play in short bursts of time, and look better than a Renaissance painting. IQ Mission from Yummy Factory is one such game, taking the very recognizable set-up of a brain training game and turning it into a spy-based series of missions around the world. On a quest for pieces of a map, you'll travel from Rapa Nui to London to Monte Carlo, solving a series of themed logic games with difficulty levels ranging from "no duh" to "...HELP!!!".

Like alchemy games like Doodle God? Well, how about trying out the authorized remake of Christian Steinruecken's The Alchemy Game? For your beloved Android device, NIAsoft brings you Alchemy Classic. From a lowly four elements, combine your way to hundreds of them as your world becomes more complex and the game gets harder! If there were ever a game to make you feel stupid for forgetting the chemical formula of methane, this certainly is it. So if you're not afraid of a little chemistry, give this free game a try!

HUEBRIX, a logic-based puzzle game by Yellow Monkey, wants your brain. Not in a zombie-eating kind of way, but in a cool, challenging way. Similar to games like PathPix and Link-a-Pix (or a number of other Conceptis releases), HUEBRIX challenges you to fill out a grid of squares by dragging "color snakes" around the board. All of this happens on a timer, so you've got to be smart, you've got to be fast, and it wouldn't hurt to have a positronic brain, either.

From the east coast of the United States to the Land of the Rising Sun, this tiny wonder of an iOS app gets you solving grid-based puzzles and get a little more cultured. From its online connectivity for multiplayer and player created maps to its rich, simple level editor, the fun keeps on coming long after you finish with the 200 single player puzzles. A set area fo plug in the pieces makes the puzzles a little more challenging, but gives an air of the Picross games most people tend to enjoy.Pick it up for a long trip or just to have whenever you need to stretch that grey matter out.

Welcome to another meeting of the society for combining things with other things. ("Hear, hear!") You may have enjoyed some previous games of this type such as the ever-popular Doodle God series. Well, we have now discovered a new game of this type called Creation HD, from Egyptian developer Accorpa. In this game, you begin with four things that are not combined with other things in any way. But by combining these things, we can come up with other things to combine into still other things with an end result of 235 things!

The great alchemy phenomenon kicked off by Doodle God is still going strong, but why simply play god when you can undertake the colonization of an entire planet? My Laboratory lets you do just that, following the same basic rules as other alchemy-based games where you drag and drop elements to create new things. You start with the four most basic elements and work towards building over 200 unique creations, from the small to large, simple to not-so-simple. The plug and chug through all of the possible ingredients will give you multiple hours of unexpected logic puzzle excitement!

Looking for a logic puzzle game that is tested and designed with cognitive physiology research AND is still fun to play? The boys over at Handy Games in Germany bring you infeCCt, a nice casual undertaking that gets you covering tiles with vines. The game will bend your mind to its limits with tons of impressively designed levels, extra obstacles and tiles for an added challenge, and online scoring system to compare your problem solving skills with others.

FlipPix Art is a series of picross logic puzzles created by GabySoft for mobile markets, including Android tablets, iPad, and NOOK Color/Tablet. The games are designed for ease of use while on the go, employing a rather unusual control mechanism that, surprisingly, makes mobile picross easier and less error-prone. On top of that, each of the games in the series features a different visual theme along with a large number of puzzles, making it one of the best ways to get a picross fix while on the go.

Binding spirits to totems isn't the sort of activity you find on your daily to-do list. With the logic puzzle game Totemo, however, you'll do it dozens upon dozens of times, all with just a few taps on your screen! It's a rare puzzle game that isn't directly inspired by the match-3 genre, and it's from the team that brought us Evac and Everlands, so you know it's got more than a few things going for it.

One area where organic intelligence beats artificial intelligence every time is finding abstract relationships between two or more things. That, and explaining exactly why Desperate Housewives is still on the air (although that still baffles most human brains). Word to Word plays on our noggin's ability to associate conceptual ideas by presenting you with two lists of words. Your job is to pair them up, tapping a word on the left and matching it to a word on the right. You can't move on until everything is correctly paired up, so you have to think both inside the box and outside of it at the same time!

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!

From the creators of Doodle God, Doodle God 2, and Doodle Devil comes another element combining game for your iOS device! Doodle Farm plays on exactly the same formula that made the first games so successful, allowing you to mix and match increasingly complex elements to expand your universe of animals one group at a time. There's discovery, there's learning, there's over 135 animals, and there's an alien dressed as a farmer. Sounds like a winner to us!

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.

Doodle God, Doodle God, does whatever a Doodle God does, clicks some elements, combines them all, which makes new ones, and creates the world, HEY THERE! You should be a Doodle God! Give this relaxing puzzle game a try and unlock your full Doodle Godly potential. And yes, I enjoy saying Doodle God.
