You start with a small snake and you need to collect green boxes in order to make him grow in size but if you become too big you might find it harder to avoid the obstacles, therefore you should also consider collecting the red boxes in order to shrink the snake down in size. You can also collect special yellow boxes which might speed up the game for a short while or increase/ decrease the amount the green/red boxes make you grow or shrink. Test your skills trying to complete various challenges in challenge mode and try to unlock various different skins by reaching specific milestones. How high can you score?
