The Icosian Game

How to Play:

The Icosian Game is a mathematical puzzle invented by William Rowan Hamilton in 1857.

Objective: Find a path that visits each vertex exactly once and returns to the starting point (a Hamiltonian cycle).

  1. Click on any vertex to start your path
  2. Continue clicking on connected vertices to extend your path
  3. Try to visit all 20 vertices without revisiting any
  4. If you complete the cycle by returning to your starting point after visiting all vertices, you win!
