Love the game...

I love the game, but there is one thing that I would love for the app developers to consider. Since iOS 14 came out, I am able to use my Apple Pencil to draw the numbers in the boxes; however, the app doesn’t recognize the number I am drawing in the box.

I have been trying to find a Sudoku app that lets me write in the numbers and have yet to find one. I would be soooo happy if they added this feature.

Either way, I give this app 5 stars. I’ve played Sudoku for a long time and I have no complaints about this app. If you love sudoku, I highly recommend you download this app. You will not be disappointed!!!

Maybe not for a purist

This takes everything out of Sodoku that I dislike and makes it more fun. In real Sodoku an early mistake can generate many other mistakes, which with this version is not possible. The highlighting number selected is good as well. They could consider trying to figure out a way for the bottom row of numbers being a little further apart, perhaps odd numbers lower and even numbers higher on the phones.

Can barely play sudoku

I loved this app. Everyday would play it and didnt really mind the ads. But now it’s unbearable. In the time I would get three or four quick games in, I now spend trying to close the app store, wait for even longer ads, and now the app itself wants me to earn points and stars, keeps showing me popups for things I dont want nor care about. I just want to play sudoku. I have collected 64 pencils and 28 hints, without watching the ads for extras. I dont use those features. The time involved just “collecting” useless features is so stupid. So now for every three to four games I used to play, I can barely get one game in.

Have deleted this app and will now go purchase a sudoku app and give my money to your competitors.
