German game by Michael Schacht and published by Queen Games (Germany 2001) and Asmodée (France 2002). 3-6 players, but best with 4. Takes about 20 minutes to play.
Different coloured cards are auctioned, so you might collect as many as possible in each colour. You are not allowed to bet the values of already collected cards and the payed price is shared among the other players, except that the excess is going to a common pool until the next turn.
