Rules states that play area cannot extend more than 4 snacks in each orthogonal direction. But I didn't understand if this means: 1) the play area must be contained in a 4x4 grid OR 2) each row/column cannot be longer than 4 snacks. It's an issue: e.g. it is possibile to have the play area, at any turn's end, arranged like XXXX XXXX O (O is the salt container)? there are two rows of 4 snacks but the play area is actually 3x5.
