Coloring Game

ENJOY THE COLORFUL WORLD & TAKE A RIDE INTO THE WORLD OF TOPOLOGY !!! There are N x N grids (cells) in this game. You can choose the board size or mode from the game's options menu. Board can be of 4x4, 5x5, 6x6, 7x7 or 8x8 size. Your task is to color all the grids (cells) in such a way that no colored grid (cell) is adjacent to the same colored grid (cell). Here adjacency means either side (edge) or vertex (node) are common. Thus 4 corner grid (cell) have 3 adjacent grids (cells). Any other grid (cell) on the boundary side has 5 adjacent grids (cells). Rest of the grid (cell) has 8 adjacent grids (cells). There are 5 colors (Red,Green,Blue,Yellow and Magenta) and you can choose one at a time. Selected color will be highlited in white boundary. If you can color the board properly with 4 colors (or 5 colors if you can't do it with 4 colors) you win the game otherwise you loose the game. Try to achieve various coloring combinations by exploring the game with your visualizing power and enjoy. Each time you play the game, you face new challenge as there are virtually infinite number of board configurations (randomly generated board). This game is a simple application of a beautiful mathematical theorem. Undo button restores the previous grid color. Clear button clears the game board. There are 2 modes (Normal and Random) of the game. By default game is started in normal mode. In normal mode all the grids (cells) are blank. In random mode some grids (cells) are randomly colored in proper way and one color is randomly seleted from the color pallette. If you switch from one mode to other, game is restarted. This game will enhance the thinking capability and visual skills of children as well as adults. This game is completely free and it has no ADS or IN-APP purchase. Limitations: In small screen color pallette images may be distorted or skewed. If there is any other bug please let me know through email
