The objective of the game is to discover the secret movie of the day. To do this, you must guess movies that you think might be similar to the secret movie. You can guess as many times as you want.
A machine learning algorithm trained on user-assigned tags to movies evaluates the similarity between the movie you guessed and the secret movie and shows you what they have in common. You can also ask for 3 hints.
