If you've been gaming as long as we have, you know that Columns is one of Sega's great puzzle games. Like most puzzle games, the object is simply to line up four same-colored gems -- horizontally, vertically or diagonally -- and watch them explode. Whether you're familiar with the game or not, we've got some good news: Sega is giving away the iPhone version of Columns for free in celebration of USA's Independence Day. The app will be free starting midnight, Friday, July 3, all the way through Monday, July 6. Sega didn't specify a timezone, so we suggest you avoid downloading it if the price reads anything other than free.
Granted, Columns Deluxe -- which includes ports of Columns and Puyo Pop -- is only $1.99 normally. It hasn't received terrific reviews either. But hey, it's hard to argue with free.
