To create a puzzle, tap the "Start" button on the screen. There are three ways to create it: "automatic questioning", "input questioning" and "pattern questioning".
1) "Auto-question" automatically creates a puzzle by tapping the "Start" button directly, and numbers (hint numbers) are displayed in some of the 9x9 squares. After creating, it will be in answer mode. If it takes a long time to create a puzzle, tap the "Stop" button (same as the "Start" button) and start over.
2) For "input questions", before tapping the "start" button, tap any square of 9x9 squares once (the background color of the tapped square changes from white to blue). This will allow you to enter a number (hint number) in that square using the number buttons at the bottom of the screen. Repeat this operation to create a puzzle on the board. Use the "B" button to clear the entered digits. To correct a number, either overwrite it with another number, or use the "<" (undo) or ">" (redo) button. After finishing the question, if you tap the "Start" button, it will automatically verify whether there is an answer or not, and then it will be in answer mode.
3) For "Pattern question", before tapping the "Start" button, tap twice on the square where the first hint number is to be placed (at this time, the background color of that square changes from white to orange), Specifies where to put the hint digits. Tap twice consecutively is only the first time, and from the next time, it will be specified with one tap. To cancel the designation, tap the orange square (at this time, the background color of the square returns to white). After specifying all squares, tap the "Start" button. This will automatically create a puzzle that matches the pattern of the specified squares. However, if the number of designated squares is 17 or less, it will be created only as a non-unique solution puzzle. When you finish creating, it will be in answer mode.
To answer the puzzle, tap the appropriate square (at this time, the background color of the square changes from white to blue), and then enter the answer number with the number buttons. In addition, when you do not know the answer square, tap the "candidate square" button to change the background color of the answerable square to blue and display it. When the background color of a blank square is blue, tapping the "Hint" button will display the numbers that can be entered in that square (if there are multiple numbers, all the numbers. If there is an optimal candidate, an arrow will indicate it) at the top of the screen. will be displayed in the comment field.
