There's a special trick when dealing with yellow and red snakes:
The white dots shows possible player's moves and the red dots indicates the snake's reaction. It tends to maintain it's current direction. Once you master it, handling several snakes becomes far easier, very predictable. (Doesn't work with green snakes).
