7th Sea Basic Rules: Playing the Game

From Introduction:

Playing 7th Sea

When you’re playing 7th Sea, you’ll find that your Hero is put in all kinds of tough situations, moments in which real danger or disastrous consequences lie just around the corner. Your Hero takes actions in response to those threats and consequences — Risks — in the hopes of saving the day, warding off fate, or just plain staying alive!

7th Sea uses 10-sided dice (which you can find in most hobby stores) to help arbitrate the success of most actions the characters take. Whenever there is an uncertain outcome for an action, the GM tells the players to roll a handful of dice, add up the numbers, and tell her the result. This total determines the degree of success or failure.
