SUDOKU Fun4Free

SUDOKU Fun4Free creates Sudoku games and offers various new ways of playing Sudoku: 1) To help in discrimination of the various digits each digit can have its own background color. The background colors can be switched on/off using the drop down list "Digits with colors". Moreover, in flower mode each digit is represented by a distinct flower without showing any digit. While the game is much more beautiful in this mode it gets harder to solve, too. 2) The possible digits for a field can be displayed on the right or bottom by checking the checkbox "Digit help". Click on the field/button of choice and watch the possible digits under the text "Possible Digits". 3) It is possible to show the solution by clicking the button "Show solution". All digits will be shown during the time span set in the edit text "Reveal time (msec)" which is set to 100 milliseconds in this free version. 4) 6 different levels of difficulty can be set, ranging from "very easy" to "impossible". The difficulty level influences the number of shown digits: The higher the level the lower the number of digits which will be shown. This results in an increase of possible digits for a hidden digit. If the checkbox named "Random hiding" is checked the hidden digits will be randomly distributed on the 9x9 grid. If unchecked the number of hidden digits in each 3x3 rectangle is the same. Random hiding is more difficult to play. 5) The state of the game can be saved to a file letting the player suspend the solution of the game and loading it again at a later date. In this free app only one filename for each difficulty level is predefined. 6) The title bar of the game shows an additional difficulty index ranging from 20 to approximately 2000. This index varies also for the same difficulty level showing the player the difficulty more exactly than before. 7) Each entered digit can be removed from the 9x9 grid if the game could not be solved using these digits. Moreover, a complete help is available. The supported languages are english and german. On a smartphone/tablet with language german the whole game including help is in german, too. Several new image modes are offered: An animal mode shows distinct animals substituting the digits. A plush toy mode shows 9 distinct soft toys representing the 9 digits. These modes are especially made for children who will have much fun when playing them. Additional languages will be supported soon.
