1. What the Doodle Lite

Rating: 4.5
Price: FREE
Downloads: 50,000-250,000

This app won the Android Developer Challenge 2 in 2009 and it’s quickly becoming a favorite among Android owners.

What the Doodle is a real-time, multiplayer, Pictionary-like game with a range of game modes, social features and more. You take turns drawing images for keywords or guessing what words the other user’s drawing might represent. The lite version is restricted to the easiest game mode. The paid version of the app is available in the Android Market for £2.99 (about $4.50 USD).

2. 2-Player Reactor

Rating: 4.5 stars
Price: FREE
Downloads: >250,000

Two-Player Reactor is a small, quick, reaction game. It measures your reflexes through a series of different modes, including word-color matching, shapes, a mouse in a maze and others. Rather than play online with true multiplayer action, the game is meant to be played with a friend as you both share the same handset.

An expanded 4-player version is also available for £1.99 (about $2.99 USD).

3. Doodle Jump

Rating: 3.5 stars
Price: $3.49
Downloads: 10,000-50,000

This popular iPhone game is also a certifiable hit on Android. The user guides “the Doodler” up a sheet of graph paper with a series of springs, jet packs and more. The game also challenges you with “baddies” to defeat along the way. For design alone, this adorable game earns high marks.

4. Abduction!

Rating: 4.5 stars
Price: FREE
Downloads: >250,000

Abduction’s premise is ridiculously charming. The herd is missing, aliens have abducted your fellow bovines and you have to follow the UFO that spirited them away.

The graphics are cute, the game play is challenging enough to be a time-killer, and the app makes good use of the vibrating and accelerometer features of your Android device.

5. Pocket Empires Online

Rating: 5
Price: FREE
Downloads: >250,000

For fans of massively multiplayer games, this casual title might be perfect. Pocket Empires allows you to “harvest, build [and] conquer,” according to its tagline.

The game features more than 10 unique structures to add to the city you’re building, more than 30 creatures to recruit or capture, and a full slate of nearly 100 enhancements for your individual stats. Its time-based system makes it easy to play in short spurts.

6. Line Rider

Rating: 3.5 stars
Price: FREE
Downloads: 10,000-50,000

Here’s a game that’s all about physics. You get to draw lines, then a little green Android robot “rides” them on a skateboard. Left-to-right lines are floors, and right-to-left lines are ceilings. You can create ramps, half-pipes, ziggurats — just about any kind of surface you can imagine.

With physics being what they are, you can also send the robot diving off a cliff or smashing into a wall.

7. Magic Gem Lite

Rating: 4 stars
Price: FREE
Downloads: 50,000-250,000

Here’s a sweet little Bejeweled clone for fans of that casual gaming evergreen. It’s the simple, familiar game we’re all used to: Multicolored gems are swapped to create lines of the same color, which disappear and are replaced my more gems. It’s mind-numbing and perfect for when you need a little time to zone out.

The $0.99 paid version has 34 “quests,” 20 “falls,” and better tasks, as well.

8. Colorix HD

Rating: 4.5 stars
Price: €1.99 (about $2.99 USD)
Downloads: 500-1,000

This Tetris-like game totally trumps Tetris in the graphics department. Colorix features 3D marbles rolling around in beautiful, HD-quality animation. Game play is quite similar, but rather than sorting shapes, you’ll be sorting groups of three colored marbles. Watch out, this game can be highly addictive and challenging.

9. City Mayor

Rating: 3 stars
Price: €1.99 (about $2.99 USD)
Downloads: 500-1,000

This SimCity clone lets you build your own town and get your world ranking. The city you build can also be displayed as your device’s wallpaper. Money is added to a player’s account every 10 minutes, so this is an excellent choice for intermittent play. Game play speeds up and features are added as your city’s population grows.

10. Guitar Hero World Tour

Rating: 3.5 stars
Price: $4.49
Downloads: 10,000-50,000

This console classic is also becoming a hit in the Android Market. The game lets you rock out on drums and guitar, and you can play live with other GHWT users. The game is bundled with 15 high-quality audio tracks. Each player gets a new song each month.

Players can also check stats and get bonus content online at the game’s companion website.
