About Tumble: Gravity Block Puzzle
Tumble is an 8×8 block puzzle with gravity: clear a line and the blocks above fall, which can set off chains. On iPhone Duo, the developer says, open and held wide, or half-folded like a book, the board takes one side of the fold and your score and pieces the other; stood like a laptop or held tall, everything you touch moves to the bottom half and the score grows on the top. Closed, it fills the cover. There are no pictures of it on the Duo yet.
