• http://2048.calebn.com/game.htm?ai=rand&arg=

The modified game adds:

• an "AI Play" button or Shift-X to toggle automated play
• X to make a single automated move
• a log window of moves and messages from the AI

The automated player is implemented as a web service at ai.py on the game host that's passed info about the game's current state and returns a text response with the first line oneof up,left,right,down and the second line as an optional message.

Probe the web service here: http://2048.calebn.com/ai/ai.py?ai=left&score=228&board=32,16,8,2,16,4,0,0,2,0,0,0,2,2,0,0&prior=lullll&drop=3,1,2

Arguments to the ai service include

• ai= which algorithm to use (specified on the url to the game)
• arg= optional args for the algo (also specified on the url to the game)
• gid= id of game, autogenerated by the client
• score= current score
• board= current board, by row in format "4,2,0,0, 4,0,0,0, 0,0,0,0, 0,0,0,0"
• prior= recent prior moves as string (e.g. "udlr" where 'u' was the most recent move)
• drop= cell dropped by game after last move as [row, col, value] (e.g. "1,0,4")
