Had another look before I saw your comment, down to 3 blocks left now (12 lines). Thought my previous one was a bit messy, much better now, not sure if it can be optimised any further. Will check your link next. :)

EDIT: Nice. I was doing it slightly different to yours, https://blockly-games.appspot.com/maze?level=10#foif9x , two if statements instead would have fixed that, and the pattern becomes perfectly clear. Cheers. :)

But that's code bingo - fewer lines, but less efficient for the mouse.
