Cross Set is a Sudoku-like brain-teasing novel number puzzle game with beautiful musics.
The feelings you will have when playing this game will be somewhat like playing Sudoku, but it's more sensible.

New Features:
- 12 Additional beautiful background musics which received favorable reviews in previous work
- 150+ Unique puzzle sets
- Infinite random puzzle
- Quicksave while playing puzzle
- Steam cloud save
- Dark backgrounds

The rule of the game is quite simple:
- There is an NxN square grid
- The grid is constrained by sets of candidates
- The solution is to have every row and column containing every number 1 through N
But the gameplay will be unexpectedly deep, when you actually play it.
