๐ How to play Whisper Sudoku
- The sudoku rules apply: 1 through 9 with no repeats in each row, column, and 3x3 box.
- On each green line, two consecutive squares on the line must differ by 5 or more. That is, |a โ b| โฅ 5.
- Click an empty square and choose a number. Each puzzle has a unique solution.
๐ก Tip: 5 can only sit next to a value that doesn't exist on the range's edge (it would need a 0 or a 10), so 5 almost never appears on a whisper line except at its ends.
โ๏ธ Notes mode: press the โ๏ธ button on the keypad (or the N key) to jot down candidates in the empty cells.
