Append this to any starting game of Polyomino

&move=aaab\|bccccd

Or any other combination that creates CORRECT shapes, but in the wrong position.

I didn't try to make the move, but the “send move” button is present. Probably a check is missing.

Maybe it is checked when you submit the move.

Carroll asked me to test it and that's the result.

Unfortunately it seems working.
Obviously it's completely useless as soon as if I propose a hacked board to Carroll he still can decide if to accept or swap, so the balance of the game is preserved.

Hacked starting position game

…and it works for any move!! I just added &move=bcccdcdd and got a small L :)
I could have swapped too.

Polyomino Easter egg: if you add & move=ac\|dc, you get a Tetris game where pieces start falling, but I could not find the keys to turn pieces, I am on Chrome!!! Anyone?

Beware Richard I think Tetris is still copyrighted, so we can't call it this way.

No really, Carroll?

Joker :D
