Sudoku16

In a normal Sudoku game, the player has to fill a 9x9 grid with digits from one to nine, in such a way that no digit appears more than once in a row, column or 3x3 sub-grid.

Sudoku16 has the same rules but the grid is much larger (16x16). This of course means that the sub-grids are also larger (4x4) and this time one of 16 different values are possible for each cell.

The program is easy to use and has a simple interface, mainly because this game doesn’t require many features.

Instead of taking the classical approach of offering the user easy puzzles in the beginning and then increasing the difficulty as they complete them, this piece of software allows the users to generate the puzzles they desire. This is done by adjusting the combo number (for selecting a random puzzle) and selecting a number of givens (how many cells are already filled in the puzzle).

The application allows the user to choose an alternative way to complete the puzzle: with characters instead of numbers or with both characters and numbers. This doesn't change the solution in any way, it’s just a method of making it easier to complete the board.
