In American card games books, two games called All Fives sometimes appear - a card game and a domino game. This page about the card game; there is a separate page for the game with dominoes.
The card game All Fives is a variation of All Fours for two or three players, in which additional points are scored for taking certain trump cards in tricks: A=4; K=3; Q=2; J=1; 10=10; 5=5.
Having introduced these extra points, some players have dropped the original points for high, low jack and game. For details, here is an archive copy Dave Barker's former page Rules for All Fives.
