Pachisi (also spelt Parcheesi, Pachisi, Parchisi, Parchesi; also known as Twenty-Five) is the National Game of India. The name comes from the Indian word "pacis" which means twenty five, the highest score that could be thrown with the cowry shells. Pachisi is, in fact, the younger sister of Chaupar (or Chausar or Chaupad, also known as Pat in Sanskrit), a more venerable, complex and skilful game that is still played in India.
