SNES Game: Super Sudoku

This is a homebrew Sudoku game cartridge for SNES, programmed for fun as part of the March 2019 RetroChallenge (project log here). One of the very few, if not the only game to support the NTT Data Keypad, besides the original JRA PAT online horse race betting system. (more info on this here)

Features:

• 4 Difficulty levels, 100 unique puzzles each. (Total of 400 puzzles!)
• Simple Hint engine. Detects sole cell candidate, unique row candidate and unique column canditate.
• Invalid entry detection.
• Auto-solver (please use it after giving up)
• Supports the NTT Data Keypad for direct number entry!
• Also supports standard SNES controllers: Use L/R to cycle through valid values for a given cell

Also available in catridge format for PAL and NTSC systems! https://www.raphnet-tech.com/products/super_sudoku/index.php
