Three Sisters is a strategic roll-and-write game about backyard farming designed by Matt Riddle and Ben Pinchback with beautiful art from Beth Sobel. Three Sisters is named after an indigenous agricultural technique still widely used today in which three different crops — in this case, pumpkins, corn, and beans — are planted close together. Corn provides a lattice for beans to climb, the beans bring nitrogen from the air into the soil, and the squash provides a natural mulch ground cover to reduce weeds and keep pests away.
