The Heroku Python template was used as starter code to build this slash command.
This is the server-side code to run the slash command, /ttt on slack channels.
There can only be one game at a time in a channel.
Options:
/ttt @opponent: start a new 3x3 tic-tac-toe game with opponent
/ttt @opponent size N: start a new NxN tic-tac-toe game with opponent
/ttt whoseturn: which user must play next
/ttt i,j: Make a move at the cell in the i'th row and the j'th col
/ttt giveup: Give up and let the other user win
/ttt help: sends help to you just like this
SECRET: You can also type in a single number to make a move on a cell to be quick. For example, for a 3x3 board, you can refer to cells the way you would on your phone's keypad, i.e.
|---|---|---|
| 1 | 2 | 3 |
|---+---+---|
| 4 | 5 | 6 |
|---+---+---|
| 7 | 8 | 9 |
|---|---|---|
Your move would look like /ttt 5 if you want to make a move in the center cell
