Quote from : Homo Ludens: A Study of the Play-Element in Culture Book

For us the chief point of interest is the place where the game is played. Generatly it is a simple circle, dyutamandalam, drawn on the ground. The circle as such, however, has a magic significance. It is drawn with great care, all sorts of precautions being taken against cheating. The players are not allowed to leave the ring until they have discharged their obligations. But, sometimes a special hall is provisionally erected for the game, and this hall is holy ground. The Mahabharata devotes a whole chapter to the erection of the dicing hall - sabha - where the Pandavas are to meet their prtners. Games, of chance, therefore, have their serious side. They are included in ritual.
