25 years of Sudoku led me to build a game for competing, learning and playing together — looking for honest feedback
Hi everyone,
I’m an independent developer and have been playing Sudoku for around 25 years.
I started developing this game for a very personal reason.
I wanted to be able to compete with my son on the same Sudoku puzzles, but I also wanted to teach my 76-year-old mum in India how to play Sudoku remotely — where we could talk while solving a puzzle and she could see the grid being solved in front of her. That made me wonder whether Sudoku could be more than a solo puzzle: One more reason was for some of us it took years to learn advanced techniques or have someone whom we could speak to so why not now use the tools around us to teach younger, older any generation to
Learn. Play. Compete. Together.
I’ve built an early playable version around that idea.
🎮 Play the game
https://v0-sudoku-rss-app.vercel.app
It currently includes:
3×3, 4×4, 6×6 and classic 9×9 grids
Multiple difficulty levels
Daily Challenge
Killer Sudoku
Tournaments
Friends and global rankings
Create Your Own Grid
A tutorial/learning path for beginners and advanced
🧪 What I’m looking for
I’d really appreciate 30–60 minutes of genuine playtesting.
Please don’t feel that you need to be an expert Sudoku player. In fact, I’d particularly like feedback from both experienced players and people who are relatively new to Sudoku.
Suggested playtest
Please:
Open the game without reading any instructions beforehand.
Spend a few minutes exploring the home screen.
Try at least one 9×9 puzzle.
Try one of the smaller grids.
Try a different difficulty.
Explore the Tournament/Friends features.
Look at the Create Your Own Grid option.
Try the tutorial if you’re new to Sudoku.
Continue playing whatever interests you.
After playing, please complete this short feedback form:

What I’d particularly like to know
Was the game immediately understandable?
Did the different grid sizes make sense?
Did you enjoy actually solving the puzzles?
What felt confusing or frustrating?
Would you want to compete with friends/family?
Does the idea of solving Sudoku remotely with another person appeal to you?
What would make you come back tomorrow?
What is the ONE thing you would change?
What is the ONE thing I should absolutely keep?
Please be honest — criticism is much more useful to me than compliments.
This is an early version, so I’m deliberately looking for things that don’t work.
Thank you to anyone willing to spend the time testing it. 🙏
I’m also very happy to answer questions about how/why I built it.
