Never played two-up before? Anzac Day is coming up, so it’s time to learn. (The Australian War Memorial website has a great little encyclopedia article about the game, as well.)

Yesterday’s Column 8 ran an interesting story from the First World War, about a player who threw 17 “heads” in a row - 34 coins coming up heads - and asks whether that could ever be bettered.

Easy math: the odds are one in 4^17, or about one in 17 billion.

Interesting, though: your odds of dying from a lightning strike on any given day are about one in 1.5 billion - so you’re ten times more likely to die from a lightning strike on Anzac Day than repeat this feat.
