Radial
Sudoku

I wanted a Sudoku app I could use with one hand. I wasn’t trying to solve some deep parenting problem. I just wanted Sudoku app that was easy/fun to use.

Other apps I tried required multi step interaction to change modes. That felt unnecessary. So I asked: what does a single-hand interaction look like?

A radial menu. Press and hold, then pick the number from the wheel. Move to the outer rim and it becomes a note instead of filling the cell.

I built most of it with Cursor agents — a little hand-holding, nothing dramatic. The radial menu was the part that actually needed me in to code. Once the raidal select felt right, the rest came together quickly.

I made it for myself because I wanted one-handed Sudoku. With agent coding, personal tools like this are easy enough that the answer is just: why not?
