This is an expansion to Coloretto Amazonas and allows 2 players to play cards in a negative way. There is a set of 4 desk cards marked with a minus symbol which are laid adjacent to a set of normal cards. The two players lay their cards on either side according to the extra rules (similar to playing cards on your side in Lost Cities). There are also some -2 tokens and a set of negative bonuses -3 to -6, presumably for the first player to make a negative set. Published in a limited edition of 2000 copies by Michael Schacht's own label Spiele aus Timbuktu, this expansion is a single sheet you must cut up to use. Expands: Coloretto Amazonas
