Tetris - In-game title
In this variation, each of the falling blocks are made up of four separate hash marks arranged in the configuration of the Tetris pieces they represent. Upon hitting a surfice, the hash marks change into O's to indicate they are no longer moveable.
The gameplay resembles that of the original game, except for the width of the width of the playing field. Here, players must earn points by composing horizontal lines consisting of twelve blocks instead of the traditional ten. The game continues indefinitely as in most other variants, but this version does not keep track of individual lines or advance levels, and the speed of the shapes' descent remains constant throughout.
