This is the home page for Falling blocks, a Free/Open Source Tetris clone. This is a very simple program that I wrote many years ago in Delphi and now ported to Lazarus. Its 'killing feature' is that you can draw your own pieces (a.k.a. tetriminos).
You can download the latest stable version of Falling blocks here.
You can read a little bit about the history of this program here.
The latest development version (which might not be suitable for production) is also available via the CVS server.
For instructions on installation and use of Falling blocks, refer to the User Manual.
If you need help or have comments/suggestions, you can contact the author.
