I just launched SudoBlock about a week ago. Check it out on itch.io: https://ndbroadbent.itch.io/su...
It's available for iOS, Android, Windows, and web. You can play online at: https://sudoblock.com
I often hear from people who think Sudoku is too hard, or they don't know how to play. This game makes Sudoku puzzles more accessible and fun, because you can match shapes as well as numbers. But if you want a challenge, then check out the Hard and Expert levels.
It's still a little rough around the edges, and there's a lot of things I want to improve. I've been getting some good feedback though, and would love to hear your thoughts.
