I found an interesting solution for the problem of not having tic-tac-toe in Slack with the use of Slack Buttons.

The app is Serverless and almost stateless running on AWS Lambda which costs me about $0.30AUD/month to support over 600 hard working Slack teams.

Someone told me that Slack internship candidates are asked to make tic-tac-toe. 😂

I made this over a weekend a while back out of curiosity and boredom.

It was a quick and hacky first attempt at Serverless which I quickly deployed onto AWS and forget about until today when I got a flurry of complaints about it was not working. Turns out there are about 1200 hardworking teams out there that rely on this productivity app. 😂
