Sudoku Ronin

Games can be played in two modes, Sudoku Classic which is a 9x9 grid and which has four levels of difficulty, or Sudoku Junior which is a 4x4 grid. Games are timed and the player is awarded points for their completion. The game supports multiple player names so a group of players can compete for top score on the high score table. The Classic puzzles can be printed, e-mailed, or changed to use letters rather than numbers. There is also an option which allows the player to manually enter puzzles and either play them or have the program solve them automatically.

APSudoku is an implementation of the classic puzzle game Sudoku, designed to interface with the Archipelago Randomizer program to earn free hints for ongoing randomizer games via completing Sudoku puzzles. Puzzle solving itself is single-player, though some features can interact with other players connected to the same Archipelago room, such as the "Death Link" feature, which can clear your grid when another player dies- or kill another player in whatever game they are playing when you submit an incorrect puzzle solution.
