Backgammon
Playing and studying backgammon — the 5,000-year-old race-and-blocking game where two players bear off fifteen checkers under the roll of the dice. The real depth is in the mathematics layered over the luck: pip counting to know who's ahead in the race, estimating winning equity, and the doubling cube, which turns every position into a wager where you must decide whether the odds justify doubling the stakes or accepting a drop. Rollouts, match equity tables, and gammon-price theory reward exactly the kind of person who likes to put a number on a hunch.
