Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
Amandakmg365: I don't understand the question either then.
If you are just looking to remove 1 piece that you don't like the placement of, then just click on that 1 piece.
If you don't like ANY of the layout of ALL of the pices, then like Mr. Shumway said - choose the "clear this position" option below the board to clear the board where you can then start over.
