Kiu kiu Kiu kiu Kiu kiu or qiu qiu is a form of dominoes popular in Indonesia related to pai gow. It may also be referred to as '99 domino poker'. It is played using a set of (28) double-six dominoes, which in Indonesia typically take the form of small cards, which are discarded after a few games as they show signs of wear. Players are typically required to pay a fixed ante into a pot, and are then dealt three domino cards. After evaluating their cards each player in turn may either bet (if there is no previous bettor), call (if
Schläfli double six double six configurations. The set of 15 lines complementary to a double six, together with the 15 tangent planes through triples of these lines, has the incidence pattern of another configuration, the Cremona–Richmond configuration. The intersection graph of the twelve lines of the double six configuration is a twelve-vertex crown graph, a bipartite graph in which each vertex is adjacent to five out of the six vertices of the opposite color. The Levi graph of the double six may be obtained by replacing each edge of the crown graph by a two-edge path. The intersection graph of the entire set
