Great game! One minor feature I would love to see... I love this app! The events are awesome and the interface is super intuitive. Also, the smart hints that don’t just give you a number and actually show you the strategy are incredible!!! One minor nitpick has to do with the tap-and-hold a number feature that allows you to quickly enter it into multiple cells. I love that when in the default entry mode, you can select a cell with a number already in it and see all of those numbered notes in bold on the other cells. Currently, when you tap-and-hold a digit, the cells containing that digit show a grey background (which is awesome!), I just wish the notes were also bolded. I find myself deselecting the held digit, tapping a cell to see the notes bolded, making a mental note of where I need to enter the new notes, and quickly going back to the held digit to enter them all (and mistakes get made Great sudoku app, best I’ve tried I spend so much time in this app, I find sudoku very soothing and the interface is smooth and great. (I’ve paid for it, because ads are not soothing and devs deserve money. And I appreciate something that doesn’t have microtransactions.) I absolutely love the “killer” sudoku in the new event, and I hope they’re introduced as a regular option to play, because I’ve just finished the event and I already miss them! My only real issue is that the 1 is so narrow and so close to the edge of the screen that it’s incredibly difficult for me to successfully hold it down to select it—a huge amount of the time I end up too far to the left and then when I try to correct I end up brushing 2 and it changes the number in whatever square I last entered and I rack up mistakes for no reason because I’m fighting with the interface. It would be nice to be able to rotate my phone sideways and have the numbers up the side of the puzzle instead. Love it! The game functions well. It features settings to change whether the game is timed, whether you want limits on how many you get incorrect, along with lots of other options. It’s very simplistic without flashy colors, and has three different color options for different times of the day (white, yellow, black) similar to functions on an internet browser, so your eyes don’t strain from white light etc. It doesn’t take up much of my battery usage, and works on airplane mode/without data, so it’s nice for a flight or a road trip. The single downside to this app is the ads before and/or after each puzzle is completed, and if you have a limit on how many you can get correct it plays an ad before you can continue, but again the limit can be turned off in the settings. Overall, this app is fantastic and I definitely recommend downloading it if you are a fan of sudoku.
