Edit: Since a recent update, the screen goes to sleep while playing so disappointed and not playing as much as I have in the past and have reduced the number of stars. Please fix. Thank you to the team at HappyDevs! This is the best sudoku available from google play, others that I've tried have adverts popping up all the time and some also have complicated interfaces. This is a pleasure to play. I like the dark screen, easier on the eye than a light screen. Many thanks!

I'm so sad that I made the mistake of updating this app, it no longer works on my phone after being my favorite time killing app for years. I've done everything the pop-up recommended, uninstalled it multiple times and even restarted my phone twice. nothing worked. time to go looking for a new sudoku app, I can only hope to find one half as good as this one used to be

Theo, I'm terribly sorry about your experience! Your device is marked as "supported" so I don't really know what the issue might be. Could you provide some details on what isn't working exactly? You can write to [email protected]

One of the only games I've played in a while, that is actually the game you expect when you download it. Have had this game for a long time and thankfully, it still doesn't spam you with ads.
