SUDOKU’S UNBOUND #3 PUZZLE FOR KINDLE AVAILABLE WITH TOUCH/WRITE TECHNOLOGY
That’s write! right! This is the first puzzle, available exclusively on Kindle Touch, that allows entry of numbers on an e-Ink device by writing with your finger.As you can see in the second image above:
‘ You can write small or large numbers, whichever you find easier.
If you write small numbers (about the size of a puzzle cell), the number will go into the cell that you write in. If you write large numbers, the number will go into the cell that you start writing in. ‘
