Three offline block puzzles for iPhone and iPad: Classic, Mosaic and Gravity.
Classic: move and rotate falling blocks, then drop them to complete horizontal lines.
Mosaic: drag a block onto the square grid, or select it and tap a cell. Full rows and columns clear together. Use all four blocks to get a fresh set.
Gravity: complete horizontal rows to switch gravity between down and up. Move left or right, rotate, then drop. The direction indicator shows which way blocks are falling.
