Cymru oedd y wlad gyntaf yn y byd i ddeddfu ar chwarae. O dan Fesur Plant a Theuluoedd (Cymru) 2010, mae dyletswydd ar awdurdodau lleol i asesu cyfleoedd chwarae i blant a sicrhau bod digon ohonynt yn eu hardaloedd.
Wales was the first country in the world to legislate for play. Under The Children and Families (Wales) Measure 2010, local authorities have a duty to assess for and secure sufficient play opportunities for children in their areas.
