One third of the proceeds from each sale (after Apple takes their cut) will be donated to Child's Play, a charity that helps sick kids in children's hospitals all over the world.

The challenging planetary puzzlers, Eliss (Steph Thirion) and Osmos (Hemisphere Games), and Darrel Johnson's parkour-platformer, Canabalt, join Tiger Style's Spider: The Secret of Bryce Manor, Mikeengreg's surreal Solipskier, and Area/Code's Tetris-Sudoku hybrid, Drop7.

You can visit the IndieSale website for a little more info about the sale its included games, or just fire up iTunes and grab any of the listed games for less than a buck.
