Test run
Our test player is deliberately simple: it presses down whenever it can, then left, then right, and up only when stuck. On this board it reached the 512 tile after 719 moves and finished with 10,128 points. Any corner plan beats that, so take it as the first mark to pass.
How to approach it
The opening tiles start away from the walls. Pick the corner closest to both and spend the first moves bringing them there.
