In Happy Snakes you have to make your snake grow as big as possible by eating the glowing pips as well as your opponent's snakes.
Your task is simple. Collect shining food throughout the playing area. Increase your body and become frightened. Defend your head and be careful not to hit another snake in the body. Do the loops and avoid others. Each time you destroy another snake, a lot of food will stay after it. If you need to run quickly, use the left mouse button. But be careful because your body is shortened.
