Perudo

Perudo is the commercial version of the Andean South American bluffing dice game Dudo (also known as Cacho, Cachito or Pico), popularised in the UK and elsewhere from the 1988 University Games edition. Each player has five dice hidden under a cup. Players bid ever-higher combinations of face value + count ('four fives!'); later bids must raise. Aces (ones) are wild. Wrongly calling 'Dudo!' costs the caller a die.
