the fifth column, and the word “bear” is hidden bottom to top in the last column.
in all of the examples so far, letters were only used in one word. to make the game a little more difficult, some words can share letters. for example, the letter “c” is used twice: once for the word “cub” in the first column, reading up, and the word “cat” mentioned before.
the highest difficulty is where words can run diagonally, from the lower left to the upper right, or from the upper right to the lower left, or from the lower right to the upper left, or from the upper left to the lower right.
