Discussion of Problem 1947. Meander

" along one of the sides of the playing board" should be removed since it gives the impression that you can only move tiles next to the edges of the board. For more clarity it could say that you can move them parallel to one side of the board, or that you can shift up to four tiles as permitted by the empty square.
