In celebration of Advent 2010, iPhone games Rayman 2 and The Screetch are free to download for today only.

Gameloft's Advent Calendar game for today, Rayman 2: The Great Escape is a direct port of the multi-platform 3D adventure game.

Using the virtual analogue controls, you guide Rayman through a world of pirate hideouts and magical powers in search of the four masks of Polokus.

Free in collaboration with Appvent Calendar, The Screetch is a challenging match-three title with a twist. A black goo slowly covers the playing area, and you have to create explosions to collect enough goo to complete each level.

Visit Pocket Gamer every day during Advent for the latest free games in the run up to Christmas.
