“Come in spinner!”

Punters will be screaming it loud and clear today as RSL clubs across the country host games of two-up in commemoration of ANZAC Day.

Typically two-up is only allowed on one day a year, April 25, so today is your chance to be a part of the fun.

It’s a game even the staunchest opponents of gambling generally oblige.

But before you walk into your local club and start betting money hand over fist, here is a guide to the game and how it’s played.

At its most basic level, the game involves one person tossing up two coins and people in the crowd betting on the outcome.

The outcomes are either two heads, two tails or “odds”, which is one of each.

Generally you can only bet on either heads or tails, and continue tossing up until you get a result.

Some venues will allow bets on odds.

The spinner will make a bet with someone in the crowd and then tosses the coins in the air, making sure they travel at least three metres in the air and land inside the ring.

Money is then exchanged depending on who won the bet.

Several bets are made among people in the crowd or “school” as it’s known, and the whole game is run by the “boxer” who stands in the middle but does not bet.

It’s the boxers job to ensure all bets are paid and people are playing fairly.

They also have discretion when it comes to weak tosses, so make sure to get those coins nice and high.

The wooden paddle used to toss the coins is called the “kip”.

The coins are always pennies from before 1939.

In most clubs you will find people betting in $5, $10 and $20 sums but you may find eager punters willing to wager a $50.

But the most important thing to remember when you’re having a beer and tossing up the coins is the men and women who sacrificed their lives to make that moment possible.

Lest we forget.
