DESCRIPTION Find the solution for your Sudoku at a split of a second! Our Sudoku solver offers not only a full solution for several levels of difficulty but also a step-by-step construction to reach the ultimate solution. Why this solver? - guarantees fast solutions - it stays a tricky puzzle game due to “hints” - fast entries through intelligent options - intuitive design USING THIS SOLVER Start the App and an empty board will show up. Through the intuitive user interface is it possible to enter your own numbers – fill in numbers in some cells and the other free cells will only show numbers that can be considered for your special Sudoku. By having chosen a wrong number, you do not need to erase all entries. Just mark the wrong number and choose a right one or erase the wrong entry. After your selection of numbers, your own created Sudoku will be shown. A step-by-step solution follows. By clicking the button “hint”, an arbitrary cell with a number will be indicated. This number brings you one step closer to your solution. From now on it won´t be possible to enter more numbers. By touching another free cell, the right number will appear. Now you can compare your number. In this way you will also come closer to your own solution. The button “solution” will give you the whole solution for your Sudoku. Variations of solutions are possible. We, the team of TIME4INNOVATION, hope that we can help to solve very tricky puzzle games and we would be glad to get a feedback!
