Your spider family has just completed an impressive web, but a neighboring family of arachnids is honing in on your territory.
It's time to claim the web as your own.
Place your nine spiders-- one at a time -- on the web. Your eight-legged competition will do the same. Get three in a row, and steal a spider from the other team. (Watch out -- the other spider family can do the same to you).
Once all spiders are placed, move them along the web one space at a time. Again, the competing spiders will move as well.
For every unique three-in-a-row you create, you'll capture a spider from the other spider family.
Can you reduce their army to just two spiders before they do the same to you?
