what's with the latest update? All the back buttons have disappeared. Access the menu & can't back out, finish a game & can't back out. It's almost as if the developer is trying to force the user to use a specific function. I do appreciate that I can still choose a pack game vs a daily challenge. When that choice disappears so will I I suppose.

Hi, thanks for your feedback! We recently made the app full-screen to comply with Google Play’s API requirements. If you’re using button-based navigation, please swipe up from the bottom to bring up the buttons and go back. Otherwise, you can also use the back arrow at the top left corner of the screen. For more help, write on scienext@live.com

This is by far the best sudoku game there is. It gives you the option to show u ur mistakes or not unlike other games. There is no ads. Exepet for the bottom. And there is 4,445 different puzzles of all difficulty levels combined. They add 1 more puzzle per day. So it keeps growing. My only problem with this game is that it's very easy to miss click ruining the pencil markings. You just have to pay attention. Amazing game.

Hands down one of the best Sudoku games out there. I didn't give ⭐⭐⭐⭐⭐, for the following reasons. 1. When you go to pencil in a number, the cells of the number you're working on are no longer highlighted. 2. Once you've completed all levels, you can't clear the whole game and start over. Once I finished all levels, I wanted to play it again. I tried deleting and reinstall it. Didn't work.
