Sudomine - Sudoku Mine Sweeper

A minimalist mashup of Sudoku. Logic puzzle perfection. The rules of the game are simple: each of the nine blocks has to contain all the numbers 1-9 within its squares. Each number can only appear once in a row, column or box. The difficulty lies in that each vertical nine-square column, or horizontal nine-square line across, within the larger square, must also contain the numbers 1-9, without repetition or omission. Every puzzle has just one correct solution.
