This is a Friday seek and spell that uses regular expressions. If you do not know what a regular expression is, you can learn here. If you want to solve this puzzle, but don’t want to learn about regex, you can use this cheat sheet. (If it’s still unclear, you can ask anything in the comments)
EDIT: Note that the first entry is broken into two lines. That is just so the image can fit nicely into the post, but has no effect on the puzzle.
If you like regex, check out regex golf.
(If you are wondering what happened to Thursday, I had a seek and spell using only ‘X’ and ‘O’, but I found it tedious/guess-and-checky. I tried to fix it but it kept breaking. I should actually test my puzzles before starting the themes, you say? Nonsense! That would require thinking ahead!)
