Let me just start off by saying, this, in my opinion, kind of gets ride of the fun to some extent. It tells you EXACTLY how to do it and gets rid of the purpose of trying to figure things out. Cross five (or called gomoku online) is a very fun game in general. I only write this guide because I feel like playing against polly/Isaac is a VERY DIFFICULT version of the game. If you do not have fun playing against Polly/Isaac normally and just want to beat him, this is for you.
Every turn I mark by number which place you need you put your piece and Polly/Isaac’s response. It’s a simple as that. They never changes their placement.
Blue = Your moves
Red = Polly/Isaac’s moves
Yellow = finishing move
