Query: Sudoku with little imagination

The product is very poorly designed. It can not use the native resolution and uses very low resolution and grabs all the screen. The aesthetic is very poor and they need to use darker lines to separate each groups of 3 X 3 squares. The color of pre-determined numbers and your entry should be completely different from each other. This product is obsolete. Don't buy it.
