Hints & Tips

Hit yourself on a Ninja Rope
Just use the Ninja Rope to cling yourself onto the ceiling. Then, use a Super or Aqua Sheep and make sure you aim it at the worm that is hanging from a Ninja Rope.

Easier win
When your in battlegrounds surrounded by a wall, look at the ceiling for ledges that one worm may be able to fit on. Then Ninja Rope up to that area and use a powerful weapon, like the Nuclear Test, and use it with that Worm. That Worm will survive, and you will win, although all other Worms will be killed.

To win a match, locate a good place to hide underground. Then use the Blow Torch to get underground. Remain there and keep skipping your turn. Then watch your enemies blow themselves up.

Stupid enemies
If your enemies are in a spot near each other with no way to reach your team, they will start to kill each other or themselves by using the weirdest ways. If one enemy is too far away from any worm on the field, they will just skip their turn.
