As the title says there is the Humble Bundle for Android. In case you don't know the Humble Bundle which is also known as the Humble Indie Bundle is an indie game bundles where you pay what you want for it and the money you use would give your a bundle of games that is DRM free and for the major platforms being PC Mac and Linux. The money that you pay being anything you like to give is for charity, the Child's Play Charity, Electronic Frontier Foundation or both.
You the user can pick how the money is given out so you can evenly split it between the two charities and nothing to anyone else or split it evenly to everyone those being the developers of the games your getting and humble bundle(if you give anything to them it would be used to pay for the servers that would host your DRM free download), also you will have more then one way to get your games from either using torrents they give you or direct downloads
This bundle is special because it comes with games what not only work on your PC, Mac or Linux but also for your Android phone, this is the first time humble bundle have done this. It should be noted that you don't need to have an Android phone to get the games because after you make a donation you will be able to get downloads of the same games for PC, Mac and Linux with Android.
I would suggest paying above the average because Humble Bundle tends to add extras games after like the first week or in some cases had a whole previous Humble bundles turning the 4 games you get right now into something close to 10 but I don't know if it will happen this time.
Final note too you will get all the games soundtracks also as apart of the Humble Bundle, this isn't just one or two tracks but the whole soundtrack for each game that is in the bundle right now, I am not sure if they are going to add more soundtracks for extra games they mad or may not add to the Humble Bundle. This is the least you can do for two great charities, your getting awesome games for super cheap and I mean cheap. I know I will be donating as soon as I can.
