Volt is a set of rules and practices designed to quickly and accurately determine the realistic outcome of a character's action, taking both skill and circumstance into account. The abilities of a character are summed up on the character sheet, and chance is represented by two twenty-sided dice (d20). No other dice or tables are used in-game.
The idea is to read through the entire text in the order it's been written, just like any ordinary book, not following any page references. The references are there to serve as a guide to the reader who, once familiar with the text, might use the text more as a reference work.
