Two-up is a game that involves tossing two coins onto a flat surface, like a table or the ground, and guessing how they will land. One person, called the "spinner," tosses the coins into the air, and everyone else places their bets on whether the coins will land "heads" or "tails" facing up.
If both coins land with the same side facing up (both heads or both tails), this is called "two-up" and the person who guessed correctly wins. If the coins land with different sides facing up, the person who guessed incorrectly loses their bet.
Two-up is an Australian gambling game that originated in the 18th century and is commonly played on ANZAC Day (April 25) to commemorate the soldiers who fought in World War I. It's a popular game that brings people together to have fun, take chances, and win prizes.
