Please help!programming an OpenGL game application with c

Hello everybody.
I am in the difficult (but also pleasant :) ) position to start coding a game application like Tetris or Pacman or Arcanoids or anything simple like these, in C language, using OpenGL libraries.

I am a starter of Using OpenGL and a moderate programmer in C language.

Is there any possibility to find ready a game like the previous or something like that ?
I have spent hours searching on internet and only i can find games in c++ using OpenGL, other games in c for DOS but nothing like what i am looking for.

How can i start writing a game like these? I mean that i have already gone through some tutorials like Nehe about OpenGL and some others but still i have some difficulties how to start writing the game.I have never tried before and i dont know how to start.I found some books about game programming but they are about c++.
I want also to let u know that i have no idea of the algorithm that these games and surely i have to start readiing first this. Can you suggest me any tutorials, pdfs, whatever, to start reading?

Any other suggestios are welcome.

Thanks....
c u :)

Just keep searching.

Why not read some tutorials, like Nehe's?

I have already gone through NeHe's tutorials at some point.Can somebody help me about the algorithm of the tetris game and the architecture of it? I mean how to start coding? Any guidelines about that?
Thanks in advance

Tetris blocks can be represented with a string.

Code:

---

string t =
" X  "
"XXX "
"    "
"    " ;

string z =
"XX  "
" XX "
"    "
"    " ;

string s =
" XX "
"XX  "
"    "
"    " ;
