I'm trying to remember an old Tetris game we had on the PC way back. I remember when you loaded the game, it gave you a page number, line number, and word number for you to look up in the manual and enter to start (to prevent piracy). It might have been DOS, I can't be sure though. But the backgrounds all seemed very Russian. One of the backgrounds was the church from Russia (http://cdn.churchm.ag/wp-content/uploads/2011/07/churches-russia-e1310923643750.jpg). Another I believe was a circus picture. And the music was awesome. Any ideas on what Tetris game this might have been?
