Playing the game, it seems like Team Github doesn't actually know the rules of the game, and are just playing optimally as if for normal tic-tac-toe. They continually force Team Twitter into the middle area (by continually playing in the middle square of each area), allowing the most dominant meta area to be given up. Looking at the numbers of people that are choosing each square, it doesn't seem like it has anything to do with the number of people on each team. Literally every single person on Team Github chose the same squares in the most crucial mistakes.

I was the only person picking for Team Twitter (team size: 5) for a while, so I was able to pick strategically while Github was often split among 2-3 choices (team size: 20).

Team Twitter was going really well around the 8 person mark vs the 20 or so on GitHub.

This was a blast. Great presentation. Who had the idea to pit GitHub vs Twitter?

It was ultimately my idea to pit these two teams together in this format but I initially got the humans vs. humans suggestion from a coworker. I initially had it as a single human team versus a computer AI but I think this makes for a more exciting matchup!
