TTTM: The machine-to-machine challenge of tic-tac-toe 🕹️

tttm is a game of tic-tac-toe played between APIs that players implement themselves.

Rules

Players can use whatever language and whatever technology.
The player must submit the URL to a server via the PR request on this repository. All player servers are listed in players.yml.
The player can submit as many servers as he or she wants.
The server needs to follow the Player Server Protocol described in this document.
The game server will randomly pick player servers and execute gameplay.
Games will be played every hour. Each server will play 100 games every hour.
The server needs to respond in 3 seconds. Otherwise, the opposing server wins.
TBD: Scoring

Players need to implement an HTTP server that needs to have one endpoint.

The game server will pass the following URL query parameters to the player server.

gid - UUID that represents the given game ID.
- It can be used on player servers to stick together individual games.
size - A number - size - of tic-tac-toe grid. By default, set to 3
playing - A symbol that the player server needs to play. Possible values are X or O
moves - A string that represents the previous moves.
- Moves are separated by - and positions by _
- Example: X_1_1-O_0_0 means that the X symbol was at location 1,1 (centre of grid) and O at 0,0 (top-left corner of the grid)

The content of the successful response (HTTP status 200) needs to be a string that should have the following structure:

Move:X_2_2

The player server replied by placing the symbol X in position 2,2 in the grid—in this case, the very bottom right.

If, for some reason, the server is unable to reply or parse, please use the following payload structure:

Error:Sorry. Can't do it bro.

tttm-randy is a sample player server implemented in Python 3 with Flask and uses "random strategy" where it will "play" any field that is empty on the given grid.

Why not? We want to see who can build the universe's fastest and most "intelligent" APIs for the lolz.
