Help!! I've been trying to beat this challenge for soooo long and now that worms 2 is out i've decided i want to finish worms once and for all but i still can't beat challenge 13... does anyone know a trick to beat this level so i can more on??

So Worms 1 you are speaking of? If so try: www.youtube.com/watch?v=b8pTJqCYwpM

Yes that's the correct game and challenge but i think they updated that because i've tried that...the water doesn't rise for me idk why
