Gameloft, one of the largest iPhone/iPad game publishers and developers, announced on its blog and Twitter page that it will be giving away ten of its iPhone/iPad games free, one every day for ten days starting Monday, May 10th thru May 21st excluding weekends. Gameloft's "iPhone Happy Hour" promotion is to celebrate Gameloft's 10th anniversary.

There is a catch, however, as the daily free game will only be available for two hours each day and users will have to follow Gameloft's Twitter page (http://twitter.com/gameloft) to find out exactly which two hours per day it will happen. Gameloft also will not reveal which games will be available on which days until it is released.

Gameloft's iPhone games include Assassin's Creed, UNO, The Oregon Trail, Let's Golf, Asphalt, Brother in Arms, Heroes of Sparta and Real Soccer. For more details, check out Gameloft's blog at http://j.mp/c3Xuyj.
