Open Worms Zone and join the battle of brave worms in an enormous arena! Grow your worm to be the largest and earn yourself a champion’s title. And don’t forget, a champion must stand out from the crowd. Choose a skin for your worm in the wardrobe or create your own cool design. There are several tactics for becoming a champion: "fighter", "trickster", or "builder". Which will you be? Regardless of the tactics you choose, there is one simple rule to remember: if you collide with an opponent — you lose! But if you manage to encircle the enemy you not only eliminate them but also steal all the tasty treats they’d picked up from them. There are also different bonuses in the arena that improve your worm’s stats. Use them wisely, and they will help you achieve your desired goals! Good luck, little worm!
