It doesn’t take a genius to figure out that puzzle games are one of the most popular genres at the App Store. A quick glance at iTunes will reveal 102 pages (and growing) of such games. While this maybe the case, it’s a safe bet to say that the majority of new puzzle releases are either complete knock offs of previous efforts or are simply uninspired. Drop7, on the other hand, isn’t one of these games. Area/Code’s relatively obscure drop ’em and match ’em puzzler is without a doubt an original “Tetris meets Sudoku” game that shouldn’t be missed by fans of the genre.
