From the introduction:
Each character is made up of Dimensions (a catchphrase encapsulating an important facet of the character). Each Dimension has 1 to 3 points; total of 7.
In a conflict, define the conflict's type and stakes. Choose a Dimension that fits the conflict. Each participant rolls Fudge dice and adds them to the appropriate Dimension (if no Dimension is appropriate, add zero). The highest result wins; ties are won by the player's character.
A conflict's winner achieves his or her stakes, while the loser takes a negative ongoing condition (like hurt). Win by 3 or more and take a positive condition (like scary).
