How to play two-up

It's the one day of the year where Australians are allowed to play the simple, and sometimes lucrative, game two-up.

Australians will head into pubs and RSLs around the country following the ANZAC memorial services to play the game classed by most states and territories as unregulated gambling.

Two-up is celebrated as an ANZAC tradition, with troops in World War I famously playing the rollicking game.

Two-up is a simple game. Two (or sometimes three) marked coins are thrown in the air from a paddle by the 'spinner'.

The hollering crowd place bets for or against the spinner, based on how the coins will land. The options are two heads, two tails or one head and one tail.

Despite being a simple game, the spinner has to be coordinated. The coins must get at least three metres of air, not touch the roof and they have to fall inside the ring.

For those excited to shout 'come in spinner,' this is the moment.

If the coins show two heads, the spinner wins. Two tails loses the spinner their bet and the right to spin. One of each means the spinner throws again.

If the coins falls outside of the player's circle they're tossed again. If not, the spinner keeps tossing the coins until two of the same side appear.

The minimum age to play is 18, and a good game of two-up can be found at most pubs and RSL clubs.
