I finally got it! You have to clear the reds to where they become the “wild” monster and then use them to help move the blue or green over the spots needed. Does that make sense?

I have been stuck as well. I am beginning to think there isn’t a way to pass this level. The red monsters take over and the black ones are relentless!

Stuck on 1055 for 2

Stuck too! Been 2 weeks
