Hello Otlan. Well, it's a little complicated to explain but basically you have to solve problems to move ahead the board. And how do you solve the problems? Well, each problem requires something (for example, 3 negotiation, 1 science, 1 combat). Those things are in dice. You have to throw the dice to see if you pass the challenge. But how many dice? And what kind of dice? (dice have different colors, with different probabilities for each result). Well, that depends of several things. For instance, what incarnation of the Doctor are you using. Or what companion is available. And what equipment. Those are all cards that you can have or not. That makes things different from one "hand" to another, which is fun.
