Very enjoyable, the ads are NOT intrusive.

I get immersed in the game play. Been playing this for years and love the changing levels of difficulty that I can pick at the beginning of the game. I can interrupt a game at any time and return later right where I left off.
Love it. Recommended

The Best Sudoku game

Awesome game. Easy to place notes and let's you know when you have entered wrong number. When correct number is placed in square, it deletes that number from others within that square.

Awesome game

I'm able to choose my level of difficulty. Sometimes I feel very strong and prefer a harder level. Other times I prefer the basic level.
