The site games.crystaloffice.com states the following, "Throughout the game, Tetris pieces fall from the top to the bottom of the playing area." I noticed that the webpage also stated " When the Tetris pieces form a solid row of blocks across the playing area, that row vanishes." They also stated " Based on the original idea TETRIS by Alexey Pajitnov. Available for Windows and OS X. Absolutely FREE! Tetris for Mac OS X. You can manipulate a piece only when it is falling. Falling blocks may be swapped, moved horizontally, or dropped to the bottom of the playing area." The meta header had game as the first keyword. This keyword was followed by gaming, arcade, and free games which isn't as important as game. The other words the site used was columns. tetcolor is also included but might not be understood by search crawlers.
