Players try to guess whether a certain thing (Range is e.g. from Pizza to Gene technology) is "In" or "Out" at the moment. One player chooses one topic/thing etc. from a given card and reads it out. Depending on the square the player stands on the others have to guess either whether the thing is "In" or "Out" generally or the players opinion about the given thing. If you guess correctly you move on - otherwise you have to go backwards.
