What a pleasure to find this free simply game. I had to sadly delete the game I had been playing for years because they suddenly imposed some new ads that played audio that you couldn’t mute. This game has everything I was looking for; several levels of difficulty, including Expert which is very challenging for me but I just can’t go back to lower levels now. The format is perfect. Numbers are sized nice and large. There’s the pencil feature to help eliminate unneeded entries. Eraser feature and the option to toggle off or on, music and sound effects. Thank you developers. Great job. You covered all the bases.

Life comes with ups and downs and causes turmoil. There is no one on this earth without a worry of something or the other. Sudoku provides that peace from everything else. It gives challenges that are usually within reach. As one ages the brain activity looses its clarity. Sudoku provides the kind of brain activity that helps straighten out complexities and thereby giving clarity and confidence. One must never give up.

The puzzles seem to be more challenging than I’m accustomed to for the levels I’m playing.I also like to be able to select the cell for my “hint” although I would like an explanation so I can learn.

Ads ruin my concentration. I’ve had to delete several others because of junk that came with them. Your first one was good so far with a simple review. A smart phone is to help me be smarter. Not to help others steal my money. Thanks for keeping it simple!
