Games are a very good way to demonstrate principlesby Andy Davis / November 12, 2015 / Leave a comment

It’s not often that the children’s maths homework sheds fresh light on the challenges of investing but I can now point to at least one occasion when it did, thanks to a simple game that our 10-year-old brought home. It’s a puzzle that anyone can try and works best as a contest between two or more players.
If you want to give it a go—and I heartily recommend it—here’s what to do. Each player draws a three-by-three grid on a piece of paper and they then take turns to roll a dice, writing whichever number they throw into one of their nine squares. The object of the game is to fill the grid with three, three-figure numbers, the winner being the player whose three numbers total closest to 1,000.
This proved a fascinating challenge. The obvious goal is to ensure each line of numbers is as close to 333 as possible but that is much easier said than done when your fortunes depend on the roll of a dice. After initially struggling, I started to think about the strategy you need to follow to arrive at the right destination, and this is when its relevance to investing started to dawn on me.
