Sudoku is a true classic that every user is familiar with from newspapers or magazines. The game displays a grid made up of 9 x 9 squares. The goal is to supplement the already existing digits in such a way that each row, column and 3 x 3 box displays the numbers from 1 through 9 only once.
The game includes three backgrounds, letting the user choose a Sudoku sheet according to his taste. Playing the game on the screen is pretty simple: an empty field is being marked with the finger. Following that, a number may be selected from a number line and inserted into the field.
Well done: the game features five levels of difficulty. The app lends a helping hand when playing the easiest level. Should the player pick a number that does not belong into the selected field, the app displays the existing conflict with other numbers in an animated fashion – and deletes the incorrectly placed digit.
