One of the betting games most closely associated with the Aussie pub was the coin game two-up, which was extremely popular during the 19th and earlier 20th century. It is most often associated with the celebration of Anzac Day on 25 April each year. In the years after World War I, it became traditional that, after the early morning commemorative service and march, ex-servicemen would gather at local pubs to drink, reminisce and play two-up. Although still technically illegal, Anzac Day two-up games are now openly played in streets and laneways outside pubs and it has become a national institution that is now generally ignored by police.
