Things to note when setting up client id for the tic tac toe sample game - mattzhao92/MinMaxCloudGame GitHub Wiki

I struggled a bit in the past hour trying to generate a client-id for the sample tic-tac-toe game.
The main thing is that I didn’t enter the correct “Authorized Javascript Origin”. So here is how it should look like:

Authorized Redirect URIs leave this empty
Authorized JavaScript Origins http://localhost:8888

if you want to host the game locally.
