 For tournaments, a large playing area is subdivided and marked off (typically using nails and string) into rectangular "marked terrains" (also known as "lanes" ("cadres") or "pistes") so that multiple games may be carried on simultaneously.For tournament play, a marked terrain is a rectangle at least wide and long.In the United States, proponents of pétanque such as author Byron Putman often urge the use of non-dedicated public terrains—public walking paths, playground areas, dirt/gravel parking lots, and baseball infields – as terrains.
