Introduction

Puzzle Game in Java is a popular problem among developers for the practice of Java which can be developed through java swing or java awt. Java Swing and AWT are graphics designing components of Java.

Puzzle Game in Java

The functionality of this game is there will be a window in which some numbers will be given, numbers in some rows will be arranged in some specific pattern, and numbers in any row will be assigned randomly. So the user has to recognize the pattern according to the numbers arranged in the arranged rows and has to arrange the numbers of the unarranged row in the same pattern as above. If the number arranged by the user is correct according to the pattern of the game, a  popup will be generated showing the message “You won!!!”.

Example

Let’s understand this problem more clearly using an example described below:

Puzzle Game in Java

Suppose we have given a number table in which one cell is empty. Now our task is to recognize the pattern in which numbers are stored in the properly arranged row of the table. In this given table, we see that when we move from left to right in the first and second row from the top, there is an increment of two. Now, as we recognize the pattern, then we will arrange the numbers of the last row in the same pattern. So when we add 14+2, it will be 16, so the next number after 14 will be 16, so we will put 16 in the next cell of 14.

Now the systematically arranged table will be:

Code 

Now we will implement the same logic as explained above to develop a Puzzle Game in Java with the help of Java Swing and Java awt.
