Tile Slide Puzzle in Visual Basic .Net

This is a slide puzzle game done totally in Visual Basic .Net. The idea of the game is to load any image file and then cut the image into square tiles in accordance with the selected dimensions (Available options: 3 x 3, 4 x 4 and 5 x 5). The user then shuffles the tiles, after doing so the last tile of the picture is erased to give space to a blank tile so that the tiles can be moved and rearranged to the initial arrangement. If the user arranges the tiles correctly he/she will be “CONGRATULATED” and the last tile will be replaced back. The user can use either Keyboard arrow keys or the mouse to move the tiles after shuffling process is done. Actually I already submitted a similar program written totally in C# . Net, a friend of mine asked me if I could do the same program in Visual Basic .Net, so I did and here it is. I hope you will enjoy the game !! :)
