This page describes the different features available to you to solve Foxy Sudoku puzzles. If you are looking to know the rules of sudoku, it's here.
Throughout this page, when we tell you to click on a cell or button, touching it if you are playing on your smartphone for example will have the same effect.
The input mode determines the way of playing. You can change it in the settings ( or F1).
Three input modes are available :
To enter a digit in a cell, first select the cell, then the digit.
To enter a digit in a cell, first select the number, then the cell.
Mixed mode is a hybrid mode that allows you to alternate between Cell-first and Digit-first modes.
Select a cell to activate Cell-first mode. The active cell is then highlighted. Click on the active cell to turn off Cell-first mode.
Lock a digit to activate Digit-first mode. The locked digit is then highlighted. To lock a number, long press it on touchscreen, or select it by holding the Ctrl key on computer. If a number is already locked, a simple click is enough to lock another one. Click on the locked digit to unlock it.
If no cell is selected and no number is locked, clicking on a number highlights it in the grid.
When you click on this button (Shift on the keyboard), you activate the entry of candidates in the cells. Clicking it again turns it off.
When you click on this button (Ctrl + Z on the keyboard), you undo your last action and return to the previous state of the grid. As long as you do not perform a new action (such as entering a number or clearing the contents of a cell), you have the option of undoing undone actions (see below).
When you click on this button (Ctrl + Shift + Z on the keyboard), you restore a previously undone action (see above).
When you click on this button (Backspace or Delete on the keyboard), if a cell is selected, you delete its contents. Otherwise, you toggle the eraser.
When you click on this button, you delete the contents of each of the cells of the grid, returning it to its initial state. Note that this action does not erase the history of actions and can therefore be canceled in the event of an error with the button .
When you click on this button (F1 on the keyboard), you open the settings window.
When you click on these buttons, you enter / exit fullscreen mode.
