Two-up will be played across the country in pubs and RSL clubs. 

It is usually illegal to play the coin game, but an exception is made on three days every year and Anzac Day is one of them.

Under the Gambling (Two-up) Act 1998, the game can be legally played on the following three days only:

The rules of the game are quite simple. 

A nominated “spinner” throws two coins (preferably pennies) in the air, above head height, from a wooden paddle known as a “kip”. 

One coin is placed heads up, the other tails up.

Players then gamble on whether both coins will land heads up or tails up. 

When thrown, the coins must stay within a designated space that is off limits to punters. 

A ringer oversees the game and ensures players are paid accordingly.

Play continues until both coins land as either heads or tails, to which there will be one winner out of the two players.

Winner takes all.

Two-up was played in trenches and on troop ships during the Gallipoli campaign in WWI, which is why it is associated with Anzac Day.
