Frequently Asked Questions


Why is the game called U61?

In fact, when I first started this project, I had called it "Tetr61s". This was because the game was at first supposed to be quite close to Tetris(c) and there's a letter in Russian which is pronounced "i" (like in "tetris") and when you write it down it looks like you have written 61.

Since the Tetris Company (http://www.tetris.com) claims to have a look-and-feel copyright on Tetris(c), and sues independant game programmers who program Tetris(c) like games, I could not call the game Tetr61s, nor make a plain Tetris(c) clone. So I decided to start a new project, more general, and change the name. So "U" is because my nickname is "U-Foot" and "61" is because it is the successor of "Tetr61s".


Can I copy the game?

Yes, since the game is Free Software (free as in speech), protected by the GPL (GNU General Public License). You should have received a copy of the GPL with the game. For more informations on the GPL, check www.gnu.org.


Why did you use ClanLib instead of SDL?

SDL starts being a quite mature library, it's widespread, present in most Linux distributions, and used by professionnals such as Loki. Therefore, one might wonder why I chose ClanLib instead, knowing that it's much harder to install and also less common library than SDL.

I chose ClanLib because is a high-level programming library, and provides much more than SDL. Its main drawback is that it's still under developpement and therefore API changes occur a bit too often for me. But its big advantage is that it provides tons of usefull functions, and has a very clean design. I also like the idea that ClanLib is developped by independant programmers, just like me.


Why did you code yet another Tetris(c) clone?
