I’ve updated my review based on the quick, positive response of the developer. Thank youAs a senior, playing from an iPhone I can basically solve each game. What I can’t do is win because as I try to enter the final number I fat finger or otherwise enter the adjacent, or wrong number. Please provide an option to disable this. Remove the color tell and I’ll gladly accept the challenge to find my error. Working against time seems a better choice than 3 typing input mistakes Thank you

Easier app than the last one. Getting the hang of it quickly

I have played Sudoku a lot and thought I was good at it, but the crazy level proved me wrong. Didn’t know they were techniques to solving, which hints show you how. Sometimes though even the hint would simply say it is too difficult and just says what a number for a random cell should be. I love the game, but the ads where the Appstore opens back to back three times in a row for a job search app or opens a browser tab for killmalware are annoying. There are also regular in-game ads which do not have a mute button, so one moment you are enjoying a quiet game and the next you are hit with a raucous ad.

Given how many users give this feedback, this app should offer a way to pay for ad free play. Those who are fine sitting through ads to play - great. However those of us here for sudoku that are interested in ad free play should have an option to upgrade or buy a pack for x time period to play ad free. Other apps offer this option. The ads are the killer to this otherwise fun Sudoku program.
