Comments on Sudoku for Android

★★★★★ Alexey Ryzhkov · Oct 24, 2024

Nice software. I missed color highlights of numbers I have input. In top difficulties it's impossible to see and roll back a bit to solve the puzzle another way. ANSWER TO REPLY: SOLVED - no item in the menu you have pointed. But the issue I met is solved. I have changed the FONT and only one biggest font has no blue highlight! Do you change the style based on font? It's totally unclear :) Good to separate it. Hope it helps someone. Cheers.

Sudoku - This is an easy-to-use game. And I have been using the App. For nearly two years (2301/22-19/11/23) and it's working fine, and fun to play. Hope you enjoy too. Well done developers! Thanks.

★★★★☆ Steven Edney · Oct 26, 2023

Other sudoku games highlight completed lines, squares. More difficult than other games

★★★★★ David Abramsky · Sep 16, 2026

Been playing this Sudoku version for years and really enjoying it.

★★☆☆☆ Cory Chandler · Feb 1, 2026

The game itself is great HOWEVER, there are to many adds that pop up, and you have to get through before you can play. IF I wanted to install another game I would go there and do so. I don't need you to try and force it down my throat!!

★☆☆☆☆ Michael New · Feb 11, 2025

Thank you for adding more hard puzzles! I have an issue, which I can't report in-app, in that some full screen ads won't go away, ever. I have a screenshot if you want it. EDIT: Thanks for your response. I'd suggest an in-app option to report these issues. And more..... This is almost unplayable. I have to stop and restart the app several times! Your suggestion doesn't work there's no x, and the FF goes to that app store. You should not allow ads that behave this way.

★☆☆☆☆ Martin Evans · Aug 18, 2023

Update - I'm downgrading my rating on AI Factory Sudoku. Now ads show up before the start of each new puzzle and last for about a half a minute. That length of time is annoying, but it's not the reason for me downgrading my rating. It's a free app, so they have to have ads to generate revenue. I understand that. The reason for my downgrade is that occasionally an ad now pops up and interrupts my game while I am in the middle of it.

★☆☆☆☆ Cori MacNaughton · May 17, 2023

I've loved this app for years, but I'm strongly considering uninstalling it, because the ads have become INTRUSIVE AND FREQUENT. It used to be that there might be an ad at the end of every other game, but now there are annoying full screen ads, that Can't BE CLOSED, often 2 or 3 times between EACH game. The developer responded to say the ads were designed to be shippable after 5 seconds, but they ARE NOT. After ANOTHER response, saying ads are shippable, they're either lying or incompetent.
