I am a big fan of what I would call "word games" that are often found in English newspapers like crosswords, cryptograms, scrambled word games, etc.
Usually games like these somehow involve overlapping letters of perpendicular words, rearranging letters to form a word, or something similar.
I wanted to know if there are similar common games in Japanese, not necessarily found in a newspaper. I found Shiritori which is kind of similar where the last (relevant) mora of a word is used to start the next word, and so on.
Does there exist a poem that uses direction to change its meaning? The comments/answers in this post may point to these not being common.
