# 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 "http://www.gnu.org".
