Introduction
The object of the game is to fill in all the missing values following certain rules. Once completed, the values are checked and if no rules were violated a score is given based on the time taken to complete the puzzle.
The working of Suduco-R
Suduco-R is unique in the following way. It works by generating values for each of the nine blocks randomly while also evaluating if they conform to the rules. This is why the generation of each puzzle take a small amount of time. The advantage is, however that every puzzle is unique or more precisely that you have a chance of 1 in 6670903752021072936960 to get the same puzzle twice (Felgenhauer and Jarvis, 2005). Furthermore the computer then randomly selects which of the numbers in each block should be shown (depending on the level settings).
Rules of Sudocu-R
The rules for Sudocu-R is the same as for any other suduko game but here is a brief overview.
Blocks
The puzzle is made up of nine big blocks (black), each containing nine small blocks (blue). When completed each big block should contain all the numbers from 1 to 9.
There are nine blocks in each row and column. Every row and every column in the puzzle should contain all the numbers from 1 to 9.
Consequences
The consequences of these rules are that no big block, row or column should have two of the same numbers. With these constraints there is usually only one solution for every puzzle.
In some rare cases more than one solution for a given puzzle can arise. This happens when two missing values in a row is the same as two missing values in another row and the open blocks are in the same column. The figure below is such a case as 2 and 7 are missing in each row. It will not matter in which order they are inserted just as long as there is one of each in the two rows. Either solution will be viable and will be evaluated as such.
A similar situation can arise within columns. Even more rarely a situation with more than two solutions may arise.
Best Times
In Sudocu-R there is also a timer during the game. After play the time taken to solve a given puzzle is recorded. The best times is recorded with the player’s name. You can view the best for each level.
Sudocu-R also has the option for any grid created to be printed. Just select the print option to have a hard copy of the puzzle to work on.
I hope that the game itself is just as enjoyable as the creation of the application.
