This game was born by a wish of my wife, an ultimate Tetris fan, to play a "nice" Tetris on the PC. Many clones of Tetris in the net were all not good enough (not nice :-), boring or simply unplayable ...). Buying such a (comparatively trivial) game was not an option. So I developed a new clone of this great game.

The game includes a lot of code not developed by me. All these "stolen" codes came from the codeguru's pages, and I think it's alright to use it. I will not mention all the developers, whose code is inside the game (I fear I will forget somebody). If you're interested, you might look into the sources to retrieve this information. Some parts of the "stolen" code were modified, so please refer to the related original article in the codeguru's pages rather than extracting it from the game's source!
Screen

To have a little bit of fun, your screen settings should support at least 256 colors. Hi- or true color would be much nicer.
Sound & Music
CGTetris makes a difference between sound and music. Sounds are implemented by using wavetable files (*.wav), while music is implemented by using MIDI files (*.mid) (You can see these files only in the sourcecode distribution. In the game distribution they are built into the game.)
You need a soundcard to hear both, sounds and music.
Furthermore you need an installation of DirectX (at least version 3). Sounds are played via DirectSound. The advantages of DirectSound over the win32 API function PlaySound(), are its lower latency and the ability to mix sounds on the fly.
CGTetris does not install DirectX, because it is alrea
