Will you consider adding an option for online sudoku battle, where two will fight against each other to achieve best time. This will eliminate all of the winging about cheating, as I can imagine there will be no pause in this mode even if incoming call takes place.
Small preview of opponents screen will make it even more competative. Obviously, as both solving same puzzle numbers will have to be replaced with say blue squares.
This will make genina app unique as noone else has this.
What do you think?
