I have been on the game marketing wagon for the past few weeks and I just noticed that Google is is offering Publishers a chance to have Adsence in the game Apps they develop for Web based Flash Only games.
  There are a few requirements your games must meet in order to be eligible:
Current Requirements

1. Game plays: Minimum 500,000 per day
2. Game types: Web-based Flash only
3. Integration: Must be technically capable of SDK integration
4. Traffic source: Must be 80% US & UK Traffic
5. Content: Family safe and targeted at users age 13 and up
6. Distribution: Must be able to report embed destination and have control over where games are distributed

  

• If you have web based Flash games that have a minimum of 500,00 per day then i'm not sure you really need Adsence depending on how much Google will pay you for Game Keywords. You can serve up your own ads with a little JavaScript and HTML and let other advertisers buy up the ad space that is available set at your own price.
  
• Flash Games are of course the best games out there to play when it comes to visuals and Gameplay. I can understand why Google would want to serve up Image rich media ads to best serve their customers.
  
• SDK integration is for the Android Platform. Google Play offers Flash Game Apps, Tools, E-Books and so much more so I suggest learning how to use the SDK  from the Android Developers site and start building your Android Apps
  
• If you are a U.S. and U.K. developer I would not worry to much about this, they need mostly English sites so Advertisers can effectively market in their targeted Geographic Location.
  
• Teenagers and adults love to play Games, most of the teens today and adults as well have smart-phones capable of downloading the Game Apps from Google Play, this is why they want you to target your games for that demographic.
  
• Google wants to know where the games are embedded for Analytics and to make sure the ads are on approved sites that are safe for their clients. Google wants to make sure you have control over your games, so you can update, Distibute and market them properly and effectively giving their advertisers a good reason why they should advertise on the Google Game advertising platform.
  

If you are already a Adsence publisher then great, in your control panel on the left hand side under more products(Pic below) you will see a link for Games, click on it and it will bring you to the Adsence for games sign up form.

I'm a Adsence publisher as you can see I have text link Ads on the top and image rich media ads on the left hand side below the navigation. I have incorporated the Google Adsence into my Android Tic Tac Toe Game by adding some simple JavaScript and HTML code from Google without signing up for the Adsence for games program. It works and display fine with relevant adds showing up based on properly placed keywords by the Ad. The game is on the Google Play site and is also updated and hosted on this site as well.

Following my example above is a alternative to make some extra revenue while you game App increases in popularity by downloads and game-play. Give the Android SDK a try and see what you think, its all about App marketing these days and it makes sense to Adsence.

I added a new game blog here on JavaScripts and More. I will be providing the source codes for javaScript, CSS, HTML and Flash codes. I also will be building games Apps for the Android, iPhone, Apple, and Windows Mobile platforms as well so you can download them from the game Blog. Visit blog by clicking on image link below or use the side navigation menus.

You can add these Free JavaScript Games to your website. Just copy and paste the code!
