It's an easy game to pick up and play, no matter what mood you're in or how long your "coffee break" happens to be!

Convenient items in adventuring, yes, but it won't save you when the Dark Knight starts getting really serious about stopping you. A knight's mettle will never be more tested and neither shall your timing skills as pits, enemies, and environmental dangers stand in your way.

Though it's a scary (if distant) thought in real life, being stranded on an island where you have to fight for survival isn't high on anyone's to-do list. Place it in a casual game, though, and we're tripping over ourselves to start the download. Sahmon Games' simulation series The Island: Castaway has been perplexing players for a few years now with its superb blend of quest-based item hunting and character managing, spawning The Island: Castaway 2 not long after the original was released.

Be prepared for the addiction to begin all over again!

Hexage, creator of Evac and Everlands, pits your human military prowess against endless alien swarm in this mobile tower defense game, Radiant Defense. Defense of your spiral reactor (which looks oddly like a stove burner) is the number one priority since it keeps out those pesky invaders from, you know, destroying all humans. Radiant Defense definitely keeps elements that you would always expect from the tower defense genre, but you remove the predetermined path and get the ability to create the path they will follow to their doom (hopefully). Lasers will fly, aliens will die, and the entire time your fingers will be nimbly working to hold off a rather comically bad invasion story unfold.

Think you have it rough cutting the lawn every week? Try navigating mud pits, crazy fences, locked gates, hidden keys, one-way doors, and dozens more obstacles, all out to make your simple chore a lot more complex.

One of the early hits on the iTunes App Store and a strong leader in Android game sales, the Doodle Jump games quickly turned into the definition of a successful mobile game.

The needs of the many outweigh the needs of the few, right? Or, perhaps more accurately, the needs of the upper classes outweigh the needs of the plebs. No matter how you dice the words, the point is it's ok to sacrifice a few little guys so the bigger, more important ones can survive. The mobile port of the browser game Dibbles: For the Greater Good illustrates just that, providing a charming and intelligent Lemmings-like game that just might make you rethink this whole "needs of the many" business.

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!

If you mixed Robot Unicorn Attack with a great big helping of Jetpack Joyride and threw it all into the ocean, this incredibly colorful arcade game would jump up and smack you with a rainbow.

Just dive right into their vast ocean home so you can begin a journey that ends only when you put the app down.

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!

The early morning car ride, the smelly waiting room, and scary needles are the worst part of a trip to the doctor. Let's face it; robots have it easy when it comes to medical care!

You think electroshock therapy wouldn't be the best method of healing, but those viruses need to be purged somehow, right?

Sometimes the best things in life are simple. Nintaii is one of those things. Similar to the mobile game Brain Cube and the browser game Bloxorz, you control a block on a maze-like stage and must guide it to the exit hole by tipping it end over end.

The title says it all: Canabalt HD is Canabalt in HD! The epically popular one button running game that originally appeared in browsers back in 2009 has made its way to the mobile scene before. There's even C64anabalt for the Commodore 64!

It's still just as easy to leap out a window and smack into another building!

Sandlot's much-loved strategic trading simulation comes to your mobile devices in this port of one of the first Tradewinds titles. Start off as the lowly captain of an itty-bitty ship as you sail around the sea, performing tasks and earning favours from governors in between buying low and selling high, and even tracking down a notorious candy-gram pirate or two. Cheeky, silly, and easy to pick up, it's not as complex as other titles but is a great way to get introduced to the series or the genre gently.

Have block, will tip it over in every direction trying to slide it through the exit pit!

The goal is to move to the exit chute so the block slides neatly through, but getting yourself in the right position at the right time takes planning, luck, and probably a lot more planning.

In the growing world of 19th century North America, supplies such as oil, lumber, and farm animals were in high demand. But with the unexplored frontier standing between civilization and the burgeoning new towns, transporting everything was more than a hassle, it was almost impossible. In the bridge building physics puzzle game LINK, you have limited resources but must somehow cross impassable gaps so heavy trains can make their way to the new world. Up for a challenge?

Well, do ya? Because if you don't, you might as well just give up now, this game is too much for you. In fact, give up writing and talking altogether. Why bother, right? Kinda hard not to accept a challenge as brazen as the one brought forth in the title of So You Think You Know Words. Fortunately, the mobile word game doesn't skimp in the content department, allowing you to spend hours on end proving that you do, indeed, know words.

Wordsplosion is a hip, stylish word game that's very similar to the classic board game Mastermind as well as the more recent Wordspector.

The mobile version of the 2011 browser game works quite well on touch screen devices, and it still provides serious challenge while looking just as cute as a button!

Hidden object games are all over the place for the Mac/Windows downloadable scene. Take a look at the mobile market, though, and you'll find the pickings a bit more slim. Narrow that search to just the good hidden object games, and the selection is even smaller. Pirate Mysteries: A Tale of Monkeys, Masks and Hidden Objects is one of the successful hidden object games on mobile devices. It manages to keep its intrigue along with a healthy amount of content while shrinking everything down to fit on smaller hardware.

Can't decide if you should play a game of solitaire or a word game? How about "both" so you can stop arguing with yourself and just play? Similar to Word Solitaire in basic concept, Deck of Words delivers exactly what it promises in the title: a deck of lettered cards that must be used to make words. Stack everything just right to spell the most valuable words you can conjure, or else you'll find yourself at the end of the pile with very little to show for your work!

Your mission is simple: eat anything smaller than you so you can get bigger! In some levels you will have to eat a certain number of fish to progress, while in others you must simply survive for a certain amount of time.

Eating food is fun. Making food is fun. Growing food is work, but it's fun. Buying food can even be fun. But what part of obtaining noms is the least entertaining? Bagging your groceries. (We would have also accepted "paying for food".) With Bag It!, a game we originally mentioned when it was released for iOS, stuffing packaged foods into a paper bag finally has some reward to it. You still have to be careful, though, because crushed eggs in a mobile game are even more disappointing than in real life!

If you've played a spot the difference game, either in your browser or on a mobile device, chances are you've seen one or more releases from Difference Games, a studio dedicated to visually stunning, easy to play spot the difference games.

A simple but fun little point-and-click adventure players of all ages will enjoy, and packed with just the right amount of puzzles for a short break of mystery.

Flaws, the interactive work of fiction from author Jon Ingold, is a difficult game to categorize as well as a different game to review. For starters, it isn't really a game in the traditional sense, more like a choose your own adventure produced for modern, Kindle-enabled devices. Then there's the nature of the story, where discussing even a few of the details can spoil whole bits of the experience. Suffice it to say, Flaws is an intriguing interactive fiction "game" about finding treasure and fame, the Andromeda galaxy, a mysterious diadem, and a possible assassination.
