A plain Tetris clone made in C. Also it is my CS50 final project. Few more words on my site.
The library ncurses is required. On Debian (and I guess on Ubuntu and such):
# apt-get install libncurses5-dev
then:
$ git clone https://github.com/MarcoLucidi01/tetris_clone.git
$ cd tetris_clone
tetris_clone$ make
tetris_clone$ ./tetris_clone # enjoy!
