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

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

Rules

Players can use any language and any technology.
The player can submit as many servers as he or she wants.
The player must submit the URL to a server via the PR request to the tttm repository - players.yml.
The player server needs to follow the Player Server Protocol described in this document.
The player server needs to respond in 2 seconds. Otherwise, the opposing server wins the game.
All players and their servers are listed in players.yml.

⚠️ As the platform and systems are still in heavy development scoring and rankings is still subject to change.
The tttm is a open-source game engine that actually executes all the matches.

The 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.
size - The size of tic-tac-toe grid.
- By default, the size is set to 3, representing the grid of size 3x3.
- Possible sizes are 3, 5 and 7.
- On grids with size 5 or 7 - four symbols are needed for a win.
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.
