Author Notes
Someone may notice that the solver cannot solve some difficult puzzles.
This is due to the fact that Adobe Flash is not designed specifically for programming, and thus it has very slow execution time.
Originally, I wrote the solver algorithm in C# and ran it in Microsoft Visual Studio.
It worked very well and solved all solvable puzzles in no time.
When I used the same algorithm and translated it into a flash, it took at least ten times longer to solve a puzzle.
To fix the problem, I deliberately cut down some of the codes into simpler version, resulting in an inferior solver.
I think the solver is still very good and can solve most of the puzzles.

I had a hard time to create the generator. Most of the articles I found in the Internet was talking about how to solve a puzzle.

There were very few articles talking about how to create a puzzle.
So, I didn’t have a clue how to do it. Anyway, I made it from scratch.
The generator has two main problems. 
First, it cannot consistently reach a desired difficulty, since it contains a lot of random elements. 
Sometimes, you will get a normal difficulty in hard difficulty.

The second problem is that it cannot create a very difficult puzzle, even though it can solve the puzzle easily.

The puzzles rarely have a hard difficulty and the hard one is not super hard.
I have to admit there are a lot of rooms to improve for the generator.
