Finally tried the Brailloku Sudoku Puzzle creator and made a puzzle totry on my Chameleon, it can't do the full line in 20 cells but it is understandable thanks to thel ines markingthe squares. I imagine a Monarch or Dot Pad ould do an amazing job with these. But either way it willbe goodenough once ifinish the Braille Sudoku puzzle boks Ihave in paper braille. Now that ihave a good Sudoku Braille set too it is awesome.
