As part of the Fourth of July celebrations, Sega is offering the iPhone/iPod Touch version of the classic puzzle game Columns for free today.

Players return to ancient Phoenicia and behold the jeweled Columns as they strategically align falling gems across, down or diagonally – racing against the clock or taking on the computer for hours of challenging gameplay. Easy to pick up, difficult to master and fiendishly addicting, Columns features Timed, Challenge and Endless modes, as well as three levels of difficulty.
