MWWG uses a roll of three six-sided dice for all task resolutions, including combat. The base chance of a character succeeding at an action is determined by the character's score in a relevant attribute (usually Strength or Dexterity), adjusted by situational modifiers (including skills) determined by the gamemaster. The player of that character then rolls three six-sided dice -- If the sum of the dice is less than or equal to the adjusted number, the character succeeds at the action. Most die roles in "Macho Women with Guns" use six-sided dice, but four-sided and three-sided dice may be needed for some rolls.
