[2] By 1848 it was well known enough for Spindler to mention it in his Vergißmeinnicht ("Forget-me-Not"), in which a young man gambles his time away in pubs playing various games including Jucker ([er] juckert).

[3] In Erckmann-Chatrian's 1864 novel L'ami Fritz, set in Alsace, there are frequent references in French to playing the game of youker as far back as the 1830s.

[5] The game also appears in an 1874 book of poetry in the dialect of the Hunsrück region of Germany in 1874[6] and in an article in a Palatinate newspaper that same year as played socially by ordinary folk alongside Tarock.

[8] Rausch (1908) states that Juckerspiel was widespread in Alsace and e Marsch mache means to take all the tricks and that the Bauer is the highest card.

[10][11] Jucker has been suggested as the ancestor of the popular American game, Euchre, on the basis of chronology, linguistics and mode of play.

19th century American sources show that eucre was being played as early as 1810[12] and that by 1829, as uker, it was played with Bowers as early as 1829 in the American Mid-West, and that Euchre was invented in America during the 1820s from the mixing of Écarté with ideas from German card games by German immigrants.

[15] His conclusion is that Euchre derives from the Alsatian game of Jucker which, in turn, is descended from Triomphe or French Ruff, probably via Bête.

Like Jucker, players receive 5 cards each and there is a bonus for a slam, known as a Durch (short for German Durchmarsch, means "marching through", taking all tricks).

The partner's cards are set aside and the player wanting to "make a march" ("einen Durchmarsch machen") leads off.
