German Solo, known locally just as Solo and historically as German Ombre, is a German 8-card plain-trick game for 4 individual players using a 32-card, German- or French-suited Skat pack. It is essentially a simplification of Quadrille, itself a 4-player adaptation of Ombre. As in Quadrille, players bid for the privilege of declaring trumps and deciding whether to play alone or with a partner. Along with Ombre, Tarock and Schafkopf, German Solo influenced the development of Skat.
