The game is easy on the eyes. Gameplay would be a lot quicker and easier if there were two keypads for number inputs. There is enough real estate to place a number input and a separate pad for notation numbers. It would only require the shrinking of the forward and backward keys and the elimination of the key that switches between number input and notation input. The most annoying part of a wonderful game is having to switch between these two functions.

Some positive points. Otherwise, don't care for the design. Needs much bolder color -- maybe even font -- after placing a number. (Right now, it's a thin yellow character, whilst the grid is a busy black and white.) Whenever you place a number (it's a 2-step process) in an incorrect black, aquare turns red and slides over to one of the numbers I'd recently set. Have to use Trash Can to remove. So, really, you can't play without any challenge. Uninstalled.

Carla, thank you for the feedback! I'll answer your comments if I get you right. First, the font numbers can be enlarged. To do this, click on the Tt icon in the right corner and adjust the cursor as you please. Second, if you want to play so that errors don't appear in red, you can also set it in the settings by selecting the "let's make mistakes"

Love this game, but it could be improved. I find it frustrating having to swap data entry modes all the time. It would be great if I could select the number I want then Tap A square once for a maybe, twice for certain and a third time to clear. Then I wouldn't have to keep flipping between digits, candidate and delete mode.

Thank you very much for the feedback! To double-click to remove a digit, please check the settings: settings/game/re-pressing the number/erase. Then, at the first click, a cell on the field is selected, the second - a number is selected, the third - when you click on the number again, it is removed on the field.
