The entire game uses six-sided dice. You roll against a Target Number, typically 10 but it can be raised or lowered by your game master. You simply roll, add, and compare.
The rules should already exclude this but in case it comes up: You never will roll more than ten dice. Any die you would roll over ten just adds a +5 to your roll total.
Oh, and your dice do explode. If your not familiar with this term it means that whenever you roll a natural six on any die you roll that die again and add the new number to the previous one. If the new roll is a six, roll again and add it up.
Here are some probability charts. The odds of hitting a TN with number of d6 are first.
