There are a lot of Android apps for kids, but here are some of the favorites for kids under 10.

1. Madera & Figaro Save the Day HD
Adorable interactive story with loads for kids to do.  Age 4.
Madera & Figaro Save the Day HD is an adorable interactive story about a monkey-and-frog superhero team on a mission to prevent a festival from being canceled. The intrepid duo must fix a stage, clear a road, bake a cake, and complete other related tasks. The activities are all preschool appropriate and each scene contains multiple interactive hotspots that will trigger animations and sounds when tapped. For Android phones, this app is known as "Save the Day."

2. Chicktionary
Egg-tertaining game builds young vocabularies. Age 7.
This word game is fun edutainment but the constant clucking might ruffle some parents' feathers. There are many levels and play can be timed or untimed so the game can be shared between kids. Our review is based on the iPhone app; the Android app may have some differences in functionality.

3. Fruit Ninja
Simple, fun chopping-flying fruit game. Age 7.
Fruit Ninja has a lot more to do with fruit than it does ninjas. Your finger is ostensibly your sword, but you never see any depictions of an actual weapon in the game. Mangos, bananas, apples, and such get sliced, but nothing else. The only thing that sprays here is fruit juice. The bombs are the only violent image in the game, and their explosions are very abstract (more like a flash of white). Of more concern might be the game's connection to the OpenFeint network, which allows kids who join to "friend" other members and exchange messages with them. Choose not to opt in to OpenFeint if your kids are under the teen age category.

4. Uno
Fun multiplayer game on same device, watch online play. Age 7.
This classic card game has an online multiplayer option that encourages kids to "make new friends" over the Internet. There are some safeguards in place to protect players, but parents should monitor kids' online interactions. For young kids, as long as you steer clear of the online multiplayer, this is a fun way to pass and play the game with family members or friends on the same device. The iPad-only HD version of the app includes a "one-device multiplayer" mode, which allows up to four people to gather around one iPad to play.

5. Backbreaker Football
Simple but entertaining football game for kids. Age 8.
this realistic football game is great for kids because it's so easy to play. Your player pops up unhurt no matter how gnarly the tackle. Parents should know that this game can connect to Facebook, so they might not want their kids to exercise that option.

6. Blow Up
Angry Birds-like toppling with more control over strategy. Age 8.
Blow Up is a puzzle game where the goal is to blow up a structure using an allocation of bombs so that the building materials land below a dashed line. The lower the materials fall below the line, the better your score. The bombs, which come in three varieties, can be set with a time delay to form a chain reaction. As the game progresses, the structures become better engineered and have obstacles on either side. There is a strange, gangly panda on each level and bonus points are awarded for knocking down a building in such a way that the panda hits a target. Points are lost for blowing up the panda who, rather like a rag doll, explodes into pieces.

7. Doodle Jump
Simple, engaging game is best for tweens and up. Age 8.
This cute tilting game is fine for most kids. However, preschoolers and younger kids might not have the required hand-eye coordination to play. Our review is based on the iPhone app; the Android app may have some differences in functionality.

8. Spaghetti and Marshmallows
Fun physics building game with a playful theme. Age 8.
Spaghetti and Marshmallows is a physics-based building game in which players use marshmallows and sticks of raw spaghetti to construct towers high enough to reach a target. This app was reviewed on a Motorola Milestone handset.

9. Star Chart
A great way to explore the skies -- just point your phone. Age 8.
Through GPS technology, this virtual Star Chart identifies for you exactly what you can find in the sky on any given day or night. All you have to do is point your Android device to an area of the sky and watch the app calibrate. For example, is that really the Big Dipper that you're looking at? Point the phone up to that area of the sky and see if the app confirms your guess. Point it down and you'll find out what people on the other side of the globe are seeing at the same moment. A revolutionary way to stargaze and learn about our galaxy.

10. Build-a-lot
Real estate made entertaining and suspenseful. Age 9.
Build-a-lot is a strategy game based on buying and selling real estate. Players will be given different challenges (earn a certain amount of money, build a certain number of Tudor homes, upgrade houses to a certain level, construct a library, etc.) that they'll have to accomplish within a time limit. Often, in order to get the money needed to buy supplies, hire workers, and so on, players will need to purchase cheap houses, fix them up, and resell them for a profit (i.e., flipping). Our review is based on the iPhone app; the Android app may have some differences in functionality.
