I would like to suggest implementation of Sudoku puzzles on playroom. that would be great! explaination here: https://www.gamesver.com/sudoku-rules-for-beginners-all-you-need-to-know/
The puzzles could be implemented in such a way that either one person, or multiple people can solve the same puzzle. whosoever solves them first wins. there could also be a time limit kind of thing where you play like blitz against another player, or play it yourself and try to beat the time you took earlier while solving the same. there could be distinct difficulty levels, easy, medium, hard, and insane, just like reversi; each difficulty level having their own distinct puzzles arranged in the increasing level of difficulty.
I am eager to know if it's viable, and what everyone else thinks about this idea.
