The historical importance of Ombre in the field of playing cards is the fact that it was the first card game in which a trump suit was established by bidding rather than by the random process of turning the first card of the stock. This game developed from Triunfo, though it was from L'Hombre that the idea of bidding was adopted into other card games such as Skat, and Tarot, which owes Hombre a good portion of its betting system as well.
