About Hi Sudoku

Hey there, I'm Russell, and I made Hi Sudoku. I love Sudoku, but nothing out there felt just right. Too many ads, ugly layouts, or just plain bad puzzles. So, as a coder, I thought, why not make my own?

Here’s the deal with Hi Sudoku:

  • No mess, no fuss puzzles. They make sense and make you think, not just random guessing. My special recipe for puzzles feels like a human made them, not a machine.
  • Our app is sleek and gets you solving right away. No clutter, no distractions. Plus, some cool shortcuts keep things speedy and fun.
  • It's got all the help you need, but only if you want it. Unlimited undos, auto-notings, and hints that don't just tell you HOW, but WHY too.

That's Hi Sudoku for you. Less talking, more puzzling. Go on, give it a go and have fun!
