Sudoku minigames are accessible from the minigame page. Sudokus bonus are earned when revealing a given castle part so it is normal to not beeing able to access all Sudoku's board until the end of the game.
Entering a sudoku minigame will cost a bit of gold but you will be rewarded by much more if you complete the Sudoku board :-)
Don't worry, if you go back to the minigame page without having completed the Sudoku, the gold is 'refund'.
The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called "boxes", "blocks", "regions", or "sub-squares") contains all of the digits from 1 to 9.
Below, a "sub-grid" is enclosed in red.
Hover a void square with the mouse pointer. A number of possible values is displayed in white. Choose a number by clicking on it with the left mouse button. Here we choose "7".
