We've just released the final version of our browser-based game - Filmillion (http://www.filmillion.com). We are often told it's pretty fun to play. Also, it is (and it will be) absolutely free.
It's a machine that asks you questions about movies. You think about a movie and answer the questions, supplying more and more movie facts. Depending on your answers, the machine tries to guess the movie. The more you play, the smarter the machine gets.
Also, you can teach the machine better guess your favorite movies (including rare ones).
We hope you like the game
Filmillion Movie Team.
