Show HN: Numbl – A daily number puzzle inspired by Wordle and Sudoku

henryjburg Friday, July 18, 2025

I had an idea for a game that fused my favorite time-waster games, Wordle and Sudoku, so I had a go at making my own daily number puzzle: Numbl

Basically, you need to fill the rows and columns with a unique set of digits 1-9 where each row or column has a constraint (sum, all odd, all even, range, etc.). It generates a puzzle each day, but you can try a random puzzle by pressing "New Game".

At work I'm easing more into using AI in my workflow so I used this as a testbed for incorporating it more (i.e. rapid prototyping and validation) without outsourcing core design or compromising engineering thinking.

I ended up with a finished product that I actually want to keep maintaining so I thought I'd share and invite any constructive advice or criticism the community would have!
