A demo is live now on https://sudoku.niklasberger.com
What I changed:
- Multiple puzzles
- Responsive design for mobile
- Cell highlighting for current row, column and other cells with the same number
- Number keypad for mobile or folks who don’t want to use the keyboard
- Fetching puzzle from backend (so you can’t cheat with F12)
- When entering a number, only the specific cell is checked against the solution with the backend
- When all cells are filled out, the entire puzzle is sent to the backend to check
- Mistake counter
- When all 9 cells of a number are correctly filled out, the number in the keypad is changed to a checkmark
Next:
- Make difficulty selector work
- Notes mode
- Maybe a nice logo or something
