Pretty straight forward really. I start off with a still image from a random movie, next poster will either guess the movie an wait for thumbs up to continue (if unsure) or reply with the correct answer and continue the game (If certain your correct) by putting up the next movie image keeping the game in play.
The answer will only be accepted if the answer is exactly correct, I.E if the movie in question happens to be Jaws 2, then Jaws 3 wouldn't be correct, "And I know the difference between the Sharks from each movie so don't try it!"
P.S try not to make the images too large.
Reply with the correct answer an the game successfully advances.
