Like games Here&39's your chance to save a few bucks on six indie champs--and support a worthy cause in the process.

'Tis the season to score iPhone, iPod, and iPad games on the cheap. First, Electronic Arts cut some 70 games to 99 cents each, a promotion that's likely to run through the holidays.

Next, Gameloft and Namco got in on the 99-cent act, as CNET's Joe Aimonetti reported earlier today.

Now, even indie developers are extending some 99-cent love, as evidenced by the Indie iPhone Holiday Sale. But in this case, there's more to it than just a price drop: the six participating developers plan to donate a third of the proceeds to charity.

The games on sale include Canabalt, Drop7, Eliss, Osmos, Solipskier, and Spider: The Secret of Bryce Manor. Not exactly well-known titles, admittedly, but each one has a user rating of at least four stars in the App Store. (Osmos is an App Store Hall-of-Famer, and both Drop7 and Spider appeared on several "top-10" lists.)

Prior to the sale, which runs until Dec. 31, each game sold for $2-4 apiece.

The developers will donate a third of the net proceeds (i.e. what's left after Apple takes its share) to Child's Play, which collects toys, games, books, and cash for kids in children's hospitals around the world.

So in addition to scooping up some great games on the cheap, you can give a little extra cheer to sick kids.

While you're at it, why not check out the Windows Holiday Bundle, which also supports a very worthwhile cause (Charity:Water). It's not iPhone-related, but it does give you $220 worth of goodies for just 19 bucks.
