Bastet is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.

Bastet is a tetris clone that stand for Bastard Tetris. It based on Petris, a public domain Tetris clone by Peter Seidler, and developed by Federico Poloni, with a complete rewrite at version 0.43. As of 2015-01-07, the latest version of the game is 0.43.1. It is licensed under GPLv3+. Version 0.37 was the first public release of the game. It is written in C++.[2]


Unlike tetris, this game sends the player the piece that he/she does not need the most rather than a random piece. Thus, it dramatically increases the difficulty of the game.


It was covered by slashdot, a popular computer and technology site.[3]
