 With better cards, the forehand could either call a King, announce a "Dreyer" (play three cards from the talon against the three other players) or a "Solo", which at that time did not mean the same as today's "Solo Rufer" but a "Solo Dreier" – where the declarer played alone against the other three without using cards from the talon.The other players could also bid these contracts.Until this new source appeared, the 1829 "Neueste Allgemeine Spielbuch" ("Latest General Book of Games") was the oldest known source for Königrufen which, as it turned out, contained an edited copy of the 1827 rules under the heading "Tappen mit König oder Tarokrufen" ("Tappen with King or Tarock Call").
