That popup of number is bad. Better move that popup as fixed numbers at bottom of puzzle and let users click on numbers from this fixed list. Many such Soduku games are doing it. Just check other soduku games.
And congrats, I saw your game being in Top new free list in India. Are you buying installs using some ads?
Thanks, I will do that and give a choice to the user to choose between the popup and fixed numbers at the bottom (after couple days). Before starting I asked from some Sudoku fans and they suggested popup, but seems the other is also nice.
Thanks, I didn’t know that. No, I am not buying installs
