It says in the rules that all four 8 cards will give you a bonus. How? I've never worked out if they all have to be visable at the same time, or got extra points for getting them.
i didn't realise that.
it might be a complete waste of time (like the bonus on space quest which was hard to get and useless once you had got it.)
given that the game is easy anyway it might be worth trying to get it to see if anything good happens.
