Can you turn all 49 squares black in only 49 moves? To change the colour of a square simply click on it, but be careful - when you do, the squares above, below and to the left and right of that square will also change. After every move, the snake will advance one square further; when it has visited all 49 squares, the game is over! But dont worry if you cant solve the puzzle - at the end of each game of 49, you will be shown how far you were from winning. Just remember - the lower the score the better!
