iPhone Giveaway of the Day - Hamiltonian

The design of Hamiltonian is inspired by Hamiltonian graph.

Each level is a Hamiltonian graph, and you need to find a Hamiltonian circuit to pass the level.
However, finding the Hamiltonian circuit is a P versus NP problem - one of the Millennium Prize Problems.

The rule is very simple:
Find a walk in the graph that visits every vertex exactly once without repeating the edges and returns to the starting vertex.

Levels are easy to difficult in design. The front level is designed very simple, and the subsequent level will slowly increase the difficulty.
Each player will eventually be stuck on a level. You'll become smarter when you pass the stuck level.
