Sudoku· Classic Puzzle Games 4+

Just a quick note to let you know how much I enjoy your site to play sudoku on! First it is designed perfectly with just the right size layout and easy to read large numbers, no ads every 2 minutes to frustrate you and loose your concentration! Choices are great as some days I feel like just easy puzzles and other days I like to challenge myself with hard or expert puzzles. I am a 77 yr old retired nurse and I find it keeps my brain active and alert and that is so important so thank you so much for your hard work in providing this site !

My preference is paper/pencil puzzles. I downloaded this to have something easier to keep me busy while waiting for my mother at medical appointments. I immediately turned the sound off so not to be disruptive to others, but when starting a new game the offensive music comes on with the ad that must be viewed for at least a few seconds. I play these games to relax, not to be competitive with other unseen people. There are two many stressors to keep this game from being fun. I don’t need a clock to race against, and would prefer that it could be toggled off. Plus, when a new game is launched, the clock starts and I lose seconds watching the ad before I can skip it. I don’t care how many mistakes I make, keep track if you must, but I would like the option to clear the board and start over like I do with paper/pencil. Inadvertent mistakes are too easy to do with an errant tap on the keyboard. I pay attention to whether it was a finger tap mistake, or a logic error. Too many logic errors I’d clear the puzzle and start over. Plus, when kicked out of a game, the offensive music starts again disrupting those around me. I don’t mind the ads, they are necessary when enjoying a free app, but sound off should mean sound off all the time. Let me enjoy myself playing the game without the sudoku police monitoring how I play.

I don’t like that when I’m using the pencil (making notes) that it won’t let me put the wrong number in. Usually I notice my mistake immediately but sometimes I’m just wrong but if the app doesn’t even let you make a mistake it’s basically playing for you. Also when I need to remove a tiny number from the box because I’ve now used that number somewhere else and it’s no longer an option for this new box I have to erase all of my notes and redo them. I should just be able to tap on the number to remove it. Also, I accidentally put a number in a box instead of making a note with the pencil. Since it was correct (it told me, I didn’t know yet that it was correct) it would let me erase it! Again! Cheating!
