Russ Cox walks through solving Advent of Code 2021 Day 21 (the Dirac dice game) using Rob Pike's Ivy calculator. The puzzle involves tracking players moving on a board with deterministic dice rolls, then expanding to quantum branching where dice split into all possible outcomes. Viewers will learn how to approach this counting problem using Ivy's array and arithmetic capabilities.
