Neon Sudoku

How to play Neon Sudoku

Tap a square or use Arrow keys, then choose a number below or type it. Three mistakes end the puzzle; press H for a hint.

Tips for a better run

Start with rows, columns or boxes that have few blanks. A digit can appear only once in each row, column and 3×3 box. Use the hint button when you are stuck, and watch the three-mistake limit.
