Sudoku Java project - Part 1

INTRODUCTION

Sudoku is the Japanese abbreviation of a phrase meaning the digits must remain single, also known as Number Place, where Su means number, doku which translates as single or bachelor. Sudoku is not a mathematical or arithmetical puzzle. It works just as well if the numbers are substituted with letters or some other symbols, but numbers work best. The aim of the puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9x9 grid made up of 3x3 sub squares or sub grids, starting with various digits given in some cells; each row, column, and set squares region must contain each of the numbers 1 to 9 exactly once. Throughout this document we refer to the whole puzzle as the grid/game board, a 3x3 sub grid as a block and the individual grids that contains the number as a cell.

The first Sudoku puzzle was created in 1979. In New York City the Sudoku puzzle appear first, which was published by the specialist puzzle publisher Dell Magazines in their magazine Dell Pencil Puzzles and word Games. First it was printed under the name "number place". Howard Garns, a retired architect and freelance puzzle constructor designed this first puzzle. This mathematical construction is inspired by the Latin square, invention of Leonhard Euler. Later the puzzle was introduced in Japan by Nikoli during 1984 as "Suji wa dokushin ni kagiru", which can be translated as "the numbers must be single" or "the numbers must occur only once", later it abbreviated as Sudoku The Sudoku puzzle can use symbols or colors instead of numerals. Sudoku is still a trademark owned by Nikoli. The the game's popularity really took off in 2005; it can now be found in many newspapers and magazines around the world. 

Rules: Solving a Sudoku puzzle can be rather tricky, but the rules of the game are quite simple. Solving a Sudoku puzzle does not require knowledge of mathematics; simple logic suffices. The objective of Sudoku is to enter a digit from 1 through 9 in each cell, in such a way that: 

❖ Each horizontal row contains each digit exactly once 

❖ Each vertical column contains each digit exactly once 

❖ Each sub grid or region contains each digit exactly once

OBJECTIVES

Undergraduate research project work is very demanding of students, of tutors and of resources and many students and the transition from traditional practical work difficult. In particular, they have unrealistic expectations of what can be achieved. In order to prepare students for their project work, some second year courses include mini-projects. This paper reports on a case study of one such mini-project: it was effective in preparing students for their project work but most students were unaware of this and as a result, many felt demoralized by their experience. A number of factors which might improve the effectiveness of mini-projects and reduce the students negative feelings were identified including making the aims and objectives unambiguous, achievable and explicit recognizing the nature and difficulty of the demands which are being made of students and providing sufficient time, support and guidance for students. In this report, we present Arrange Quick Styles Drawing the detailed development and implementation of simple Sudoku game. The Sudoku game consists of graphical user interface, solver and puzzle generator; implemented using java and java swings. The solver and generator is implemented using efficient algorithm. The solver finds the solution to the puzzles generated by the generator as well as to the puzzles entered by the user Generator creates various number of different Sudoku puzzles. This project gives an insight into the different aspects of java programming. The objective of the proposed Project is to increase the Thinking Capability. The Game having all the records which you perform in playing you can Select Easy, hard level according to your choice. You can make your own Sudoku and at any Step you can go back to One Step as well as you can see the Solution of it. It is manually a very difficult job to perform and its need a lot of recalling, reminding and mathematical calculation. The game of "Sudoku" helps to increase mental thinking, vision etc.
