Fudge dice are six-sided dice with two "plus" sides, two "minus" sides, and two blank sides, for use with Fudge and other games. Rolling four Fudge dice returns results from -4 to +4 ("sub-Terrible" to "trans-Superb" in Fudge terms). The "GM's Pack" comes with enough dice for the GM and 4 players—20 dice!
