Sudoku Koubou ships with a handful of styles that change the appearance of sudoku puzzles. New styles are always under development. A style is a collection of images that form a "skin" for the various parts and states of the game, and a long list of geometric values to help Sudoku Koubou place this images correctly.

These styles are build into the SudokuMedia.dll file. If you would like to see more styles, there are two ways currently: Ask us, or open the code and DIY. The former is easier, while the latter may get results more quickly!

Entry numbers in Sudoku Koubou use colors to indicate various states of the board. There are 2 states:

• Starting values, which are given before the puzzle is begun
• Entered values, which are placed by the player while solving

You can also control the colors of the mark numbers. These smaller numbers used a fixed font to avoid bleeding over the boundaries of the cell. To help anyone who prefers certain colors of others, you may change the "unset" and "set" colors of the mark numbers.
