I wrote a FREE and ad-free Sudoku online game

[dcc909]

My father-in-law wanted to play Sudoku to keep his brain sharp, but the games available to download either cost money or are full of ads. So, I used AI to help him build a web game.

It features multiple difficulty levels, leaderboards, daily challenges, technique tutorials, and more. Most importantly, it is 100% free and completely ad-free! I hope this helps everyone who loves Sudoku, and I welcome your feedback
