Players place control markers on various edges of an icosahedron, rotating it with each play, aiming to control facets or planes of cleavage. 3 main variations/win conditions for ICO: Beginner -- be the first to have your color on 3 sides of a triangle. (Beginner+ -- be the first to have your color on 3 sides of two different triangles directly across from each other) Intermediate -- be the first to complete a full route around the entire icosahedron. Advanced -- be the first to complete an entire pentagon: sides and middle rungs. Note that when you complete the outside of a pentagon, you remove all opponents pieces from the middle rungs of that pentagon!
