Invented in 1857 by the Irish mathematician Sir William Rowan Hamilton, the game is played on the edges of a dodecahedron.
Your Goal: Find a Hamiltonian Cycle. You must trace a path that visits every single one of the 20 vertices exactly once, and then returns to the starting point.
How to play:
- Tap any vertex to start.
- Tap adjacent (connected) vertices to extend your path.
- Valid next moves are highlighted in green.
- Tap the current end vertex to undo a step.
- 3D Mode: Drag anywhere to rotate the shape!
