Place the given words into the grid, according to the following rules: Each word starts in a grey cell. The next letter must be placed in the horizontally or vertically adjacent cell indicated by the direction of the arrow. Any further letter must be placed horizontally or vertically adjacent to the preceding letter. Words may overlap each other, but no word may use one field more than once. Multiple words can start in the same grey cell if and only if there are multiple arrows emanating from that cell. A letter in a grey cell must be the starting letter for at least one word. Cells may remain empty. Each letter must be used by at least one word.
