Every so often a casual game comes along that’s entirely simple, entirely original, and entirely addictive. Area/code’s
Drop7, which challenges players to line up numbered balls in a grid seven squares wide and seven squares high, definitely falls in that category. Like Tetris or Bejeweled, it’s easy to learn, difficult to master, and even harder to put down.
Like any great puzzle, Drop7 is a game of both skill and luck. Eliminate one ball, and it may spark a chain reaction, clearly the board in dramatic bursts and multiplying your score. Each new row of balls that appears however comes up gray and number-less, and has to be cracked open by eliminating others around it. With Normal, Hardcore, and Sequence modes — the last of which challenges you to try over and over with the same combinations — this simple game never gets boring.
Drop7 is compatible with any iPhone or iPod touch running the iPhone 2.1 software update.
