2048 Bot

Bot that plays the popular 2048 game for you.

The strategy is as follows: we calculate a score for every direction except up; this is the score that you would get moving left/right/down added to the highest scoring direction from your new position. We exclude the upwards direction in order to force all the high value blocks to remain on the bottom row. We then compare these scores and move in the direction which has the highest score. In the case where moving down has the same score as left/right, we move down to ensure that high value blocks remain on the bottom row. In the case of a tie going left and right, we simply choose a direction at random. In the case where the only move is up, we make sure to move down the very next turn.

It has beat the game before, though not consistantly.
