Math Horizons Contents—April 2015

Games are extra fun for math lovers. We can play them, we can study them, and we can make them. In this issue of Math Horizons Pamela Pierce and Robert Wooster use Markov chains to decide when to attack in Risk. Burkard Polster analyzes the card game Spot It! and uses mathematics create variations of this game. Darren Glass writes about the math in an NPR quiz program. ZenZen (a KenKen game using modular arithmetic) and Spirograph also make an appearance. Read about these games and more in this issue of Math Horizons. —Dave Richeson
