Ratings and reviews

9/15/17: Fun and addictive. 3/15/19: I've played a TON of the games, and each of them are different. Each game is challenging (to the degree of low, med., high, etc.), and the game is STILL addictive. Keeps the brain cells functioning, and defeats boredom. Had the 'pencil' option, and for the more challenging levels, it really comes in handy! It's got a timer option so you can play against the clock, and it's also set up so that you can see how your time ranks with others. Definite fun!

Love the game, but the ads make it unplayable. They freeze the touchscreen and often times produce an extremely rapid click sound when you try and close the ad. Other times, the ad will finish with the link to the Google Play Store and there is no way to get back to the game. One must close the game down and restart it to be able to play another puzzle. Please fix this issue. Additionally, one can spend the coins to get rid of ads for however long, and it doesn't work.

THE BEST SUDOKU application I've ever played, and I've tried a few! Notes are easy to make, and are a automatically removed when you finally choose a number. The games range from super easy to stupidly hard, and there is a wide variety of styles. It's easy to get new puzzles off the 'net,' as well as input your own. I love it!
