Icosien is a challenging online math puzzle game based upon The Icosian game, also called the Hamiltonian game (the problem of finding a Hamiltonian cycle along the edges of an dodecahedron, i.e., a path such that every vertex is visited a single time, no edge is visited twice, and the ending point is the same as the starting point).
Icosien is a lovely online version and of course the object stays the same. Click on a nail as start point and then wrap the string around the nails to match the outline. Map all lines only one time and don’t overlap lines. Happy Puzzling!
