Since monks are not permitted to participate in archery they indulge in another popular sports called the ''daygo'' - a stone throwing sport, which involves throwing flat circular stone like a discus. Another shot put type game known as ''pungdo'' is popular and is also played with big and heavy stones. One more typical Bhutanese game is the dart game, known locally as ''Khuru'', which is played with short targets. The darts used in the game are made of a wood block set with a nail with fins of chicken feather.
