Have you ever thought that Tetris is evil because it never sends you that straight "I" brick you need to clear four rows? Well, Tetris(R) probably is not so malevolent, but Bastet certainly is. >:->
Bastet stands for "bastard tetris", and is a simple ncurses-based Tetris(R) clone for Linux. Instead of choosing the next block randomly, this fiendish program uses a special algorithm to give you the worst possible brick. Playing Bastet can be a very frustrating experience! *

( *: bonus points for presenting it to your friends as "just another Tetris clone")

Further information is in the README file inside the package, so go grab it now.

For information, bugs, feature requests, and highscores you can send me an e-mail. Due to popular request, a short description of how the algorithm works is now on-line.


In 2010, Bastet has been discussed in the xkcd forum in the discussion of a comic with a similar theme. If you do not know xkcd yet, check it out, it's awesome.

On April 2005, Slashdot has published an article about Bastet (0.41), which makes me very proud of my creature :-)
Go read the comments, as usual they are the best part of Slashdot.




Bastet is now hosted on github; check that page for the development version. Releases:

Linux binary


If you don't think it is too frustrating to run both Windows and Bastet at the same time...

Unsorted patches and material

Thanks to everyone who mailed me about bugs in Bastet, I hope the next version will fix them all (and be much more bastard than you can even imagine)


Version 0.43 was published after a long hiatus, due to me working on other projects [including graduating ;-) ]. If I get enough feedback from my (real-life) friends, who already spent a lot of time on 0.37 and 0.41, I could go on. Some bugfixes will probably be needed soon.
