Cribbage, hole by hole.
Six cards, two to the crib, a starter, and a walk up a board of 121 holes. This site follows the American Cribbage Congress tournament chart for how a hand is counted, and it sets the invention story beside the older game it grew from.

Cribbage is a card game in which the object is to form counting combinations that traditionally are scored by moving pegs on a special cribbage board.1 The object of the American Cribbage Congress tournament game is to be the first player to score 121 points.2
In the two-player game the dealer, after a mandatory cut by the pone (the non-dealer), deals one card alternately to each player, beginning with the pone, until each has six cards.2 Each player discards two cards to form the crib, which belongs to the dealer.2
