I've been playing a lot of board and card games recently. It is something that I, my partner, and our friends do several days each week to wind down in the evenings. I didn't grow up playing many games, so learning them as an adult has revealed some fascinating insights.
First, all games exist on a spectrum, with one pole being chance and the other skill. You can see this with blackjack (no card counting allowed) representing chance and chess representing skill. Most games fall somewhere in between, involving strategy as well as an element of randomness.
