The site www.ocelular.net offers several high quality mobile games to download for free. There, the games are divided into two types of categories: for screen resolution and also by type of game. Each game is presented with one or multiple photos into an animation. There is also a text explaining the game''s history and context in which it is being released.
All games are selected from the site and no bad game is loaded, going against what happens to most sites of this kind that clog the user with any game in sight just to be games aplenty.
The site also has an explanation about how to know what is the resolution screen of your phone so you can download the games correct. It is a good site and I advise everyone to visit.
