This is the best design of a Sudoku app I’ve encountered. No excessive and annoying frills to turn off or get around. The notes are easy to use. And the clearing of notes when a choice is made let’s you focus on the game and less on the mechanics. Two things would be great enhancements: make a PC version and a load your own puzzle from another source.

Sudoku is a fun yet challenging game that keeps your mind working and can help you to keep your brain working as it is meant to. Most people are unaware that Sudoku was created by a Nebraska newspaper writer which failed to begin with and was started again in Japan where it went over like gangbusters with the people there. Eventually it was started in the U.S. with the title of Number Place. Over the years it has gained popularity all over the world and remains with the name Sudoku. I started with the easy Sudoku puzzles and soon found myself doing the hard puzzles including the challenger level puzzles. I still Love to do them and don’t have any plans to stop. I hope whoever reads this enjoys them and if you have never tried playing them it would be a great time to start! Have a great day everyone and enjoy your lives as I continue to enjoy mine. Goodbye everyone! 😊

I have come to enjoy the additional challenges of the different versions of Sudoku presented in this app. I really enjoy the Samurai version on my iPad. After a recent update, I was unable to load the Samurai version, so I reached out to Boy Howdy. The response was pretty much immediate and they kept in touch until the issue was resolved. Great games, awesome service.

Love this! No timer (change in settings) or score, so it’s not some competition; it’s about solving the puzzle, period. NO Ads between games (yes!) & the only add is a SMALL banner across the bottom. Four different versions; games are numbered and must be passed to go onto next puzzle.

Please let developer know if you’re interested in Ad-free. Original review: Please create Ad free version, I’m sure a lot of us are willing to pay for that. The Ad gets in the way of playing and ruins game play experience. Please reply back with response. Updated: Developer replied back. Basically the developer indicated the ad doesn’t interfere with game play. I’m sure I’m not the only one when playing the game, the palm of my hand touches the ad box at the bottom and the ad pops up. This happens frequently...very annoying. If the developer can’t provide an ad free version (which I’m sure many of us will be glad to pay), at least provide us an option where the ad would show on top of the screen instead of the bottom of the screen. Thanks!
