Click on the screen to begin your journey as a tiny worm. Move your worm around the arena by swiping in the direction you want to go. Devour smaller creatures to increase in size and strength. Dodge larger enemies that can consume you. Use your increased size to defeat previously larger enemies. Endure as long as possible to earn a high score. Keep an eye on hazards that can halt your game prematurely. Move forward by eating enough to transform into a more powerful creature.
